</TABLE>
 
     SEE "RISK FACTORS" BEGINNING ON PAGE S-25 OF THIS PROSPECTUS SUPPLEMENT AND
ON PAGE 2 OF THE ACCOMPANYING PROSPECTUS FOR A DESCRIPTION OF CERTAIN MATTERS
THAT YOU SHOULD CONSIDER IN CONNECTION WITH OUR OFFER, INCLUDING THE FOLLOWING:
 
     - We determined the offer consideration without any arms-length
       negotiations. Accordingly, our offer consideration may not reflect the
       fair market value of your units. As of October 31, 1997, your general
       partner (which is our affiliate) estimated the net asset value of your
       units to be $715.00 per unit and an affiliate estimated the net
       liquidation value of your units to be $737.85 per unit. It is possible
       that if the offer is not successful, we may revise or terminate the offer
       or conduct a subsequent offer at a higher or lower price.
 
     - Your general partner is an affiliate of ours and, therefore, has
       substantial conflicts of interest with respect to our offer. We are
       making this offer with a view to making a profit, and therefore, 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. Consequently, there are
       substantial conflicts of interest between you and us.
 
     - If we acquire additional units in your partnership, we will increase our
       ability to influence voting decisions of your partnership and may control
       any vote of the limited partners.
 
     - An investment in our securities involves real estate investment,
       financing, management, acquisition and development risks.
 
     - We may change our investment, acquisition and financing policies without
       a vote of our securityholders.
 
     - If you acquire our securities, the nature of your investment will change
       from holding an interest in a few properties to holding an interest in
       our large portfolio of properties. In the future, the properties owned by
       your partnership may outperform our portfolio of assets.
 
     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 SUPPLEMENT OR THE ACCOMPANYING
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 OFFER. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

                     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
     Shelter Properties IV. For each unit that you tender, you may choose to
     receive 20.20 of our 8.0% Partnership Preferred Units (also referred to as
     "Preferred OP Units"),                of our Partnership Common Units (also
     referred to as "Common OP Units"), or $505.00 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 31, 1998,
     AIMCO was the largest owner and manager of multifamily apartment properties
     in the United States, with a total portfolio of 386,430 apartment units in
     2,240 properties located in 49 states, the District of Columbia and Puerto
     Rico. As of September 30, 1998, AIMCO had total assets of $3,121.9 million,
     total debt of $1,275.4 million and stockholders' equity of $1,521.5
     million. On a pro forma basis, giving effect to our recently completed
     merger with Insignia Financial Group, Inc. and related transactions, as of
     September 30, 1998, AIMCO had total assets of $4,389.4 million, total debt
     of $1,627.8 million and stockholders' equity of $2,074.3 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 a majority ownership interest in Shelter Realty IV
     Corporation, the managing general partner of your partnership (the "general
     partner"), and the company that manages the property owned by your
     partnership.
 
Q:   WHAT IS THE HISTORY OF YOUR PARTNERSHIP?
 
A:   Your partnership was formed in August 21, 1981 and sold $40,000,000 of
     limited partnership units in 1982 for $1,000.00 per unit. Between November
     1, 1992 and July 31, 1998 your partnership made a total of $53.80 of
     distributions per unit. At the time of the initial offering it was
     contemplated in the offering memorandum that the properties to be purchased
     by the partnership would be sold within three to eight years. We do not
     know why the partnership did not sell all of its properties within such
     holding period. Your partnership currently owns three apartment properties.
 
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 PREFERRED OP UNITS?
 
A:   Preferred OP Units are a class of our Partnership Preferred Units.
     Preferred OP Units are not listed on any national securities exchange nor
     quoted on NASDAQ. There is no active trading market for Preferred OP Units
     and none is likely to develop because they are subject to restrictions on
     transfer. The holders of the Preferred OP Units must hold such units for
     one year, subject to certain exceptions. However, after a one-year holding
     period, a holder of 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 NYSE.
 
                                       S-1
<PAGE>   7
 
Q:   WHAT ARE COMMON OP UNITS?
 
A:   The Common OP Units are our Partnership Common Units. Common OP Units are
     not listed on any national securities exchange nor quoted on NASDAQ. There
     is no active trading market for Common OP Units and none is likely to
     develop because they are subject to restrictions on transfer. The holders
     of the Common OP Units must hold such units for one year, subject to
     certain exceptions. However, after a one-year holding period, a holder of
     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 NYSE under the symbol
     "AIV."
 
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.
 
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:   Your general partner (which is our affiliate) 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 NASDAQ,
     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 sales transactions in the units have been
     effectuated. Based on information recorded by the general partner of your
     partnership, we believe that sales prices for your units have ranged from
     $175.00 per unit to $500.00 per unit from November 1, 1995 through July 31,
     1998. As of October 31, 1997, your general partner estimated the net asset
     value of your units to be $715.00 per unit and an affiliate of your general
     partner estimated the net liquidation value of your units to be $737.85 per
     unit. However, we do not believe that these valuations represent the
     current fair market value of your units.
 
Q:   HOW WAS THE CASH OFFER CONSIDERATION FOR MY UNITS DETERMINED?
 
A:   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 PREFERRED OP UNITS TO BE OFFERED IN
     EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by the $25 liquidation preference
     of the Preferred OP Units.
 
Q:   HOW DID YOU DETERMINE THE NUMBER OF COMMON OP UNITS TO BE OFFERED IN
     EXCHANGE FOR MY UNITS?
 
A:   We divided the cash offer consideration by $     , which represents the
     average closing price of the AIMCO Class A Common Stock on the NYSE for the
     20 trading days prior to          , 1998.
 
                                       S-2
<PAGE>   8
 
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER
     CONSIDERATION?
 
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 (which is our affiliate). 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 Preferred OP Units, 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:   ARE THERE ANY RESTRICTIONS ON THE NUMBER OF UNITS I MAY TENDER?
 
A:   No. However, if you tender less than all of your units, you must continue
     to hold at least three units (except for units held by IRAs and Keogh
     Plans) following our acceptance of tendered units.
 
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE PREFERRED OP
     UNITS, COMMON OP UNITS OR CASH?
 
A:   You have until                  , 1999 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1999 deadline, we will deliver to you the Preferred OP Units, 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 listed on the back
     cover of this Prospectus Supplement.

                                    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. Through
wholly owned subsidiaries, AIMCO acts as the sole general partner of, and owns
approximately an 83% interest in, the AIMCO Operating Partnership. As of October
31, 1998, our portfolio of owned or managed properties included 386,430
apartment units in 2,240 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 31, 1998, we:
 
     - owned or controlled 62,955 units in 241 apartment properties;
 
     - held an equity interest in 168,746 units in 897 apartment properties; and
 
     - managed 154,729 units in 1,102 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.
 
AFFILIATION WITH YOUR GENERAL PARTNER
 
     As a result of our October 1, 1998 merger with Insignia Financial Group,
Inc., we acquired a majority ownership interest in the general partner (which is
our affiliate) of your partnership and the company that manages the property
owned by your partnership.
 
THE OFFER
 
     In exchange for each of your units, we are offering you a choice of:
 
     - 20.20 of our Preferred OP Units;
 
     -        of our Common OP Units; or
 
     - $505.00 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 accept all of the outstanding units tendered in response to our
offer. 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
  , 1999, unless we extend the deadline.
 
RISK FACTORS
 
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-25 of this Prospectus Supplement and on page 2 of the
accompanying Prospectus. The following highlights some of the risks associated
with our offer and the potential disadvantages of the offer to you and should be
considered when you review "Summary -- Background and Reasons for the
Offer -- Expected Benefits of the 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
 
                                       S-4
<PAGE>   10
 
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. It is possible that if the
offer is not successful, we may revise or terminate the offer or conduct a
subsequent offer at a higher or lower price. Such a decision will depend, among
other things, on the performance of the partnership, prevailing interest rates,
and our interest in acquiring additional limited partnership interests.
 
     OFFER CONSIDERATION MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your
partnership's properties may outperform our larger, more diversified portfolio
of assets. Although we cannot predict the future value of your partnership's
properties, 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 until your partnership is
liquidated. However, you may prefer to receive the offer consideration now
rather than wait for uncertain future net liquidation proceeds. As of October
31, 1997, your general partner (which is our affiliate) estimated the net asset
value of your units to be $715.00 per unit and an affiliate of your general
partner estimated the net liquidation value of your units to be $737.85 per
unit. However, we do not believe that these valuations represent the current
fair market value of your units.
 
     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. Based
on information recorded by your general partner (which is our affiliate), we
believe that sales prices for your units have ranged from $175.00 per unit to
$500.00 per unit from November 1, 1995 to July 31, 1998.
 
     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.
 
                                       S-5
<PAGE>   11
 
     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 Internal
Revenue Code of 1986, as amended. The particular tax consequences of the offer
to you 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 (which is our affiliate) 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 few
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.
 
     CERTAIN RISKS RELATED TO OUR SECURITIES. Investors in our partnership must
hold their units for one year, subject to certain exceptions. Thereafter holders
may transfer such partnership units under certain conditions. Holders of the
units in our partnership do not have the right to remove the general partner,
and therefore, they cannot effect a change of control of the AIMCO Operating
Partnership. On and after             ,   20  , we may reduce, within certain
limits, the rate of distributions required to be paid on the Preferred OP Units,
thus reducing the rate of return and possibly encouraging you to redeem such
units. On and after             , 20  , we may redeem each share of Series I
Preferred Stock for $25, plus any accrued but unpaid dividends, possibly forcing
you to sell such shares to AIMCO or to sell in the open market at a possible
lower price per share than would have occurred without the redemption.
 
     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.
 
                                       S-6
<PAGE>   12
 
     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 and, in fact, may be able to control any vote of the limited
partners. Also, removal of your general partner (which is our affiliate) 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 2,240 properties with
386,430 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 NEGATIVE OUTLOOK FOR AIMCO RATINGS. Recently, Moody's Investors
Service ("Moody's") revised its outlook for our ratings from stable to negative
to reflect its concerns surrounding our ability to successfully implement our
financial strategy while maintaining a prudent capital structure as a result of
more difficult general capital market conditions. Moody's noted that our 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 a class
of Preferred Stock proposed to be issued by us. Moody's indicated that its
rating action reflects our 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
our high level of encumbered properties and material investments in loans to
highly leveraged partnerships in which we own a general partnership interest. At
the same time, Moody's, Standard & Poor's and Duff & Phelps confirmed their
existing rating on our preferred stock and senior debt.
 
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of
September 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.
 
     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.
 
                                       S-8
<PAGE>   14
 
     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 of the Board and Chief Executive
Officer, 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 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.
 
     POSSIBLE REDUCTION OF AVAILABLE INFORMATION ABOUT YOUR PARTNERSHIP. If
there are less than 300 unitholders in your partnership upon consummation of the
offer, your partnership could cease filing periodic reports with the SEC, such
as yearly reports, including annual audited financial statements, and quarterly
reports containing unaudited quarterly financial statements, on Form 10-KSB and
Form 10-QSB. Such reports are publicly available and can be obtained on the
SEC's web site. The lack of such filings could affect the already limited
secondary market which currently exists for units in your partnership and may
result in others not tendering for such units. In such a case, you would
regularly have access only to the limited information your partnership's
agreement of limited partnership requires your general partner (which is our
affiliate) to provide each year, which information consists primarily of tax
information.

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 a majority ownership interest in the general partner of your
partnership and the company that manages the property owned by your partnership.
Through our subsidiaries, we currently own, in the aggregate, approximately a
40.08% interest in your partnership.
 
     One of the consequences of the merger with Insignia is to allow us to make
the exchange offer and, if successful, to increase our ownership 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 October 20, 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
(which is our affiliate):
 
        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 (which is our
     affiliate) 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 Preferred
OP Units:
 
     - Enhanced Liquidity. While holders of the Preferred OP Units must hold
       such units for one year, subject to certain exceptions, 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 NYSE.
 
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Preferred OP Units.
 
     - Preferred Quarterly Distributions. Your partnership paid distributions of
       $16.07 for the nine months ended July 31, 1998. We will pay fixed
       quarterly distributions of $0.50 per unit (equivalent to $2.00 on an
       annualized basis) on the Preferred OP Units before any distributions are
       paid to holders of Common OP Units. This is equivalent to a distribution
       of $40.40 per year on the number of Preferred OP Units you will receive
       in exchange for each of your partnership units. However, one class of
       outstanding Partnership Preferred Units has prior distribution rights and
       the Preferred OP Units rank equal to seven 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 Common OP
Units:
 
     - Enhanced Liquidity. While the holders of the Common Units OP Units must
       hold such units for one year, subject to certain exceptions, 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 NYSE.
 
     - 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. Your partnership paid distributions of $16.07
       for the nine months ended July 31, 1998. We pay quarterly distributions
       on the Common OP Units. For the quarter ended September 30, 1998, we paid
       distributions of $0.5625 on each of the Common OP Units (equivalent to
       $2.25 on an annual basis). This is equivalent to a distribution of $
       per year on the number of Common OP Units you will receive in exchange
       for each of your partnership units.
 
     - 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 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-12
<PAGE>   18
 
to the offer. The offer will not affect the operation of your partnership's
property because your general partner (which is our affiliate) 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 or
control 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 (which is our affiliate),
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 accompanying Prospectus 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 $50,000.
 
     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.
 
     No Dissenters' Rights. You are not entitled to dissenters' (appraisal)
rights in connection with the offer.
 
     Other Offers. The AIMCO Operating Partnership is also making similar
exchange offers to approximately      other limited partnerships in which it
owns a majority interest and controls the general partner, substantially all of
which were acquired in the merger on October 1, 1998 with Insignia Financial
Group, Inc. Each of such exchange offers are being made by a separate prospectus
supplement similar to this Prospectus Supplement. The effects of the exchange
offers may be different for limited partners in each partnership. In general, we
do not believe any of the risk factors (except for certain tax-related risk
factors) described herein for the offer will differ substantially from the other
offers.
 
     Previously, affiliates of Insignia Financial Group, Inc. made cash tender
offers to limited partners of certain of the partnerships which are subject to
the exchange offers and which are public partnerships. For such cash tender
offers outstanding on the date Insignia Financial Group, Inc. merged into AIMCO,
we extended such cash offers to inform the limited partners of our acquisition
of control and all such cash tender offers expired on December   , 1998. For
information regarding the prior cash tender offers made to you and the other
limited partners of your partnership, see "Background and Reasons for the
Offer -- Previous Tender Offers."

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 Preferred OP
Units or 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 value of each
property owned by your partnership using the direct capitalization method. This
method involves applying a capitalization rate to the property's annual net
operating income. We determined appropriate capitalization rates using our best
judgment, but our valuation is just an estimate. In estimating the
capitalization rate, we considered the property's physical condition, location
and above-market mortgage interest rates. In addition, we considered the recent
decline in the real estate markets, and the decline in the availability of
commercial mortgage financing and the recent bankruptcy of a major provider of
subordinated 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 a 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 Preferred OP Units we are offering for
each of your units, we divided the cash offer consideration by the $25
liquidation preference of each Preferred OP Unit to get 20.20 per unit.
 
     In order to determine the number of 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 average closing price of AIMCO's Class
A Common Stock on the NYSE for the 20 trading days prior to                ,
1998.
 
FAIRNESS OF THE OFFER
 
     Fairness to Unitholders. We have a majority ownership interest in your
general partner (which is our affiliate). 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. Your general partner did not
participate in the structuring of the offer. We and your general partner believe
that the offer is fair to you and the other limited partners of your
partnership. 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.
 
     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 (which is our affiliate) 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 (which is our affiliate) 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 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
 
                                      S-15
<PAGE>   21
 
opinion, Stanger concluded that our offer consideration is fair to you from a
financial point of view. Stanger has rendered similar fairness opinions with
regard to the other tender offers being made by the AIMCO Operating Partnership.
Stanger rendered the opinions only as to the individual fairness of the offer
consideration in each proposed exchange offer.
 
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, your general
partner (which is our affiliate) 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, Preferred
OP Units and 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.
 
     As of November 30, 1998, the AIMCO Operating Partnership has approximately
9,648,794 Common OP Units outstanding and no Preferred OP Units outstanding. If
you elect to receive OP Units, you will receive a relatively insignificant
number of OP Units in the AIMCO Operating Partnership. In the offer you could
elect to receive $505.00 in cash,        Common OP Units or 20.20 Preferred OP
Units. Both your units and the OP Units are subject to transfer restrictions and
it is unlikely that a real trading market will ever develop for any of such
securities. If and when you may seek to redeem OP Units for AIMCO Class A Common
Stock or Class I Preferred Stock of AIMCO, no assurances can be given that such
shares of AIMCO will be trading at a price equal to or in excess of $          .
 
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 a
majority of both the general partner of your partnership and the manager of your
partnership's property. The general partner does not receive an annual
management fee but may receive reimbursements for expenses incurred in its
capacity as general partner. The general partner of your partnership received
total fees and reimbursements of $158,000 for the nine months ended July 31,
1998. The property manager received management fees of $430,000 for the nine
months ended July 31, 1998. We have no current intention of changing the fee
structure for your general partner or for your property manager.
 
     Competition Among Properties. Your partnership's properties 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
 
                                      S-16
<PAGE>   22
 
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
 
     Shelter Properties IV was organized on August 21, 1981, under the laws of
the State of South Carolina. Its primary business is real estate ownership and
related operations. Your partnership was formed for the purpose of making
investments in various types of real properties which offer potential capital
appreciation and cash distributions to its limited partners. Your partnership's
investment portfolio currently consists of the following three residential
apartment complexes: Baymeadows Apartments, a 904-unit complex in Jacksonville,
Florida; Quail Run Apartments, a 332-unit complex in Columbia, South Carolina;
and Countrywood Village Apartments, a 384-unit complex in Raleigh, North
Carolina. The general partner of your partnership is Shelter Realty IV
Corporation, which is a majority-owned subsidiary of AIMCO. A majority-owned
subsidiary of AIMCO serves as a manager of the properties owned by your
partnership. As of September 15, 1998, there were 49,995 units of limited
partnership interest issued and outstanding, which were held of record by 3,676
limited partners. Your partnership's principal executive offices are located at
1873 South Bellaire Street, 17th Floor, Denver, Colorado 80222, and its
telephone number at that address is (303) 757-8101. For additional information
about your partnership, please refer to the annual and quarterly reports
prepared by your partnership which accompany this Prospectus Supplement.
 
     Your partnership sold $40,000,000 of limited partnership units in 1982 for
$1,000.00 per unit. Between November 1, 1992 and July 31, 1998 your partnership
made a total of $53.80 of distributions per unit. At the time of the initial
offering it was contemplated in the prospectus that the properties to be
purchased by the partnership would be sold within three to eight years. We do
not know why the partnership did not sell all of its properties within such
holding period. Your partnership currently owns three apartment properties.
 
     Property Management. Since December 1990, your partnership's property has
been managed by 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 an
affiliate of your general partner and us.
 
     Investment Objectives and Policies; Sale or Financing of Investments. The
principal investment objectives of your partnership are to preserve invested
capital, to maximize the potential for appreciation in property values and to
provide for partially tax sheltered cash distributions. Under your partnership
agreement, your partnership is permitted to raise new capital and reinvest cash
in new properties. Your partnership will terminate on December 31, 2022, unless
earlier dissolved. Your general partner has no present intention to liquidate,
sell, finance or refinance your partnership 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.

SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     We expect that approximately $15,300,000 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)  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.

funds from operations:

                        THE AIMCO OPERATING PARTNERSHIP
 
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of AIMCO. AIMCO is a real estate investment
trust that owns and manages multifamily apartment properties throughout the
United States. As of October 31, 1998, AIMCO, through its wholly owned
subsidiaries, AIMCO-GP, Inc., the sole general partner of the AIMCO Operating
Partnership (the "AIMCO GP"), and AIMCO-LP, Inc., a limited partner in the AIMCO
Operating Partnership (the "Special Limited Partner"), held approximately an 83%
interest in the AIMCO Operating Partnership. Based on apartment unit data
compiled as of January 1, 1998 by the National Multi Housing Council, we believe
that, as of October 31, 1998, AIMCO was the largest owner and manager of
multifamily apartment properties in the United States, with a total portfolio of
386,430 apartment units in 2,240 properties located in 49 states, the District
of Columbia and Puerto Rico. As of October 31, 1998, AIMCO:
 
     - owned or controlled 62,955 units in 241 apartment properties;
 
     - held an equity interest in 168,746 units in 897 apartment properties; and
 
     - managed 154,729 units in 1,102 apartment properties for third party
       owners and affiliates.
 
     AIMCO's Class A Common Stock is listed and traded on the NYSE under the
symbol "AIV." On December 4, 1998, the last reported sale price of AIMCO Class A
Common Stock on the NYSE was $35 3/8. 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 Common OP Units for the same periods.

                                  RISK FACTORS
 
     The following sets forth certain risks and possible disadvantages of the
offer and should be read and considered when reviewing the potential benefits of
the offer set forth in "Background and Reasons for the Offer -- Expected
Benefits of the Offer." In addition, you should review the other risks of
investing in us beginning on page 2 of our accompanying Prospectus.
 
                                      S-24
<PAGE>   30
 
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. Based on information recorded by the general partner of your partnership,
we believe that sales prices for your units have ranged from $175.00 per unit to
$500.00 per unit from November 1, 1995 to July 31, 1998. As of October 31, 1997,
your general partner estimated the net asset value of your units to be $715.00
per unit. However, we do not believe that these valuations represent the current
fair market value of 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. It is possible that if the offer
is not successful, we may revise or terminate the offer or conduct a subsequent
offer at a higher or lower price. Such a decision will depend, among other
things, on the performance of the partnership, prevailing interest rates, and
our interest in acquiring additional limited partnership interests.
 
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership's
properties may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership's properties,
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. As of October 31, 1997, an affiliate of your general
partner (which is our affiliate) estimated the net liquidation value of your
units to be $737.85 per unit. However, we do not believe that this valuation
represents the current fair market value of your units. 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 properties 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
 
                                      S-25
<PAGE>   31
 
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 Internal
Revenue Code of 1986, as amended. 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 whether you 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 few 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. Under the AIMCO Operating Partnership Agreement, the
general partner has the ability, without the concurrence of the limited
partners, to acquire and dispose of properties and to borrow funds. Further,
while it is the intent to distribute net income from operations, sales and
refinancing of your partnership, the general partner may not make such
distributions. The AIMCO Operating Partnership generally makes the same
distribution on the Common OP Units as AIMCO pays dividends on its Class A
Common Stock. Further, AIMCO must distribute a significant percentage of its
consolidated revenues each year in order to retain its status as a REIT. Your
partnership is permitted not to make distributions under certain circumstances
such as reinvesting in your partnership. Proceeds of future asset sales or
refinancings by the AIMCO Operating Partnership generally will be reinvested
rather than distributed.
 
                                      S-26
<PAGE>   32
 
     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.
 
     CERTAIN RISKS RELATED TO OUR SECURITIES. Investors in our partnership must
hold their units for one year, subject to certain exceptions. Thereafter holders
may transfer such partnership units under certain conditions, including the
general partner's right of first refusal. Holders of the units in our
partnership do not have the right to remove the general partner, and therefore,
they cannot effect a change of control of the AIMCO Operating Partnership. On
and after             , 20  , we may reduce, within certain limits, the rate of
distributions required to be paid on the Preferred OP Units, thus reducing the
rate of return and possibly encouraging you to redeem such units. On and after
            , 20  , we may redeem each share of Series I Preferred Stock for
$25, plus any accrued but unpaid dividends, possibly forcing you to sell such
shares to AIMCO or to sell in the open market at a possible lower price per
share than would have occurred without the redemption.
 
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.
 
     POSSIBLE REDUCTION OF AVAILABLE INFORMATION ABOUT YOUR PARTNERSHIP. If
there are less than 300 unitholders in your partnership upon consummation of the
offer, your partnership could cease filing periodic reports with the SEC, such
as yearly reports, including annual audited financial statements, and quarterly
reports containing unaudited quarterly financial statements, on Form 10-KSB and
Form 10-QSB. Such reports are publicly available and can be obtained on the
SEC's web site. The lack of such filings could affect the already limited
secondary market which currently exists for units in your partnership and may
result in others not tendering for such units. In such a case, you would
regularly have access only to the limited information your partnership's
agreement of limited partnership requires your general partner (which is our
affiliate) to provide each year, which information consists primarily of tax
information.
 
     DIFFERENT DISTRIBUTIONS. Anticipated annualized distributions with respect
to the Preferred OP Units are $2.00 and current annualized distributions with
respect to the Common OP Units are $2.25. This is equivalent to distributions of
$40.40 per year on the number of Preferred OP Units, or distributions of
$       per year on the number of Common OP Units, that you would receive in
exchange for each of your partnership's units. Distributions with respect to
your units for the nine months ended July 31, 1998 were $16.07 per unit. See
"Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
 
                                      S-27
<PAGE>   33
 
     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 and may control such voting decisions. 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 a majority of 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 (which is our affiliate)
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 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. In determining the amount
of units to tender for, we took into account the number of units transferred in
the past twelve months so as to allow for other transfers without crossing the
50% threshold. It is possible that beginning twelve months after the closing of
this offer, or possibly earlier, we may make another offer for your units and
such offer may or may not be at a higher price.
 
GENERAL
 
     MOODY'S NEGATIVE OUTLOOK FOR AIMCO RATINGS. Recently, Moody's revised its
outlook for our ratings from stable to negative to reflect its concerns
surrounding our ability to successfully implement our financial strategy while
maintaining a prudent capital structure as a result of more difficult general
capital market conditions. Moody's noted that our 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 a class of preferred stock
proposed to be issued by us. Moody's indicated that its rating action reflects
our 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 our high level of encumbered
properties and material investments in loans to highly leveraged partnerships in
which we own a general partnership interest. At the same time, Moody's, Standard
& Poor's and Duff & Phelps confirmed their existing ratings on our 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 approximately 51% of the outstanding common shares of beneficial
interest of Insignia Properties Trust ("IPT"). The general partner of your
partnership is a wholly owned subsidiary of IPT. Through the Insignia Merger,
AIMCO also acquired a majority ownership interest in the entity that manages the
properties owned by your partnership. Through subsidiaries, AIMCO currently
owns, in the aggregate, approximately a 40.08% interest in your partnership.
 
     IPT and AIMCO have entered into an agreement and plan of merger, dated as
of October 1, 1998 (the "IPT Merger Agreement"), pursuant to which IPT is to be
merged into AIMCO or a subsidiary of AIMCO (the "IPT Merger"). The IPT Merger
Agreement provides that, upon consummation of the IPT Merger, IPT shareholders
will receive $13.25 per share in cash or $13.28 per share in shares of AIMCO's
Class A Common Stock, at AIMCO's option. The transactions contemplated by the
IPT Merger Agreement are subject to certain conditions. The IPT Merger requires
the approval of the holders of a majority of the outstanding IPT Shares. AIMCO
has agreed to vote all of the IPT Shares owned by it in favor of the IPT Merger
and the related merger agreement and granted an irrevocable proxy to certain
affiliates of IPT to vote such shares. Accordingly, IPT shareholder approval is
assured.
 
     One of the consequences of our acquiring Insignia is that it allowed us to
make the exchange offers to acquire limited partnership interests of some of the
limited partnerships formerly controlled or managed by Insignia (the "Insignia
Partnerships"). If we are successful, we will increase our ownership in 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. As of December   , 1998, the AIMCO Operating
Partnership has made offers to           of the Insignia Partnerships, including
your partnership.
 
  Previous Tender Offers
 
     Prior to the Insignia Merger, a number of tender offers had been made to
acquire units of your partnership. On July 21, 1998, Cooper River Properties,
L.L.C., then an affiliate of Insignia and now our affiliate, commenced a tender
offer pursuant to which it acquired 3,685 units (representing approximately 7.4%
of the number outstanding) at a cash purchase price of $500 per unit.
 
     We are aware that tender offers may have been made by unaffiliated third
parties to acquire units in your partnership in exchange for cash. We are
unaware of the amounts offered, terms, tendering parties or number of units
involved in these tender offers.
 
  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 October 20, 1998 for Stanger to provide such 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
(which is our affiliate).
 
  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
would generally result in significant amounts of taxable income to you and your
partners. In the opinion of your general partner (which is our affiliate), 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 could 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 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.
 
  Alternative Structures Considered.
 
     We chose to make this offer as a tender/exchange offer because other forms
of reorganization such as a merger would have meant that holders of a majority
of the units in your partnership would bind all limited partners. With a
tender/exchange offer, each limited partner makes his own decision which does
not bind the other partners. Further, we have not offered to purchase all of the
units in your partnership which would occur in other types of reorganizations or
combinations.
 
                                      S-30
<PAGE>   36
 
  Sale of Assets
 
     Your partnership could sell the properties it owns and not liquidate. The
general partner of your partnership considers sale of your partnership's
properties from time to time. However, any such sale would likely be a taxable
transaction.
 
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. While holders of the Preferred OP Units must hold
       such units for one year, subject to certain exceptions, 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 NYSE.
 
     - 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 $0.50 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 Preferred OP Units rank equal to seven 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. While the holders of the Common OP Units must hold
       such units for one year, subject to certain exceptions, 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 NYSE.
 
     - 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 September 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 all of the outstanding 49,995 units of your
partnership, which we do not directly or indirectly own, for consideration per
unit of (i) 20.20 Preferred OP Units, (ii)        Common OP Units, or (iii)
$505.00 in cash. If you tender units pursuant to our offer, you may choose to
receive any of such forms of consideration for your units or any combination of
such forms of consideration.
 
     The purchase price per unit will automatically be reduced by the aggregate
amount of distributions per unit, if any, made by your partnership to you on or
after             , 1998 and prior to the date on which we acquire your units
pursuant to our offer.
 
     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                  , 1999,
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.
 
     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             , 1999.
 
     This offer is being mailed to the persons shown by your partnership's
records to have been limited partners or, in the case of units owned of record
by IRAs and qualified plans, beneficial owners of units, as of             ,
1999.
 
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 which are validly tendered and not withdrawn prior to the expiration
of the offer as promptly as practicable following 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             ,
1999, 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 IPT or Insignia
Properties, L.P. ("IPLP"). 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.
However, if you tender less than all of your units, you must continue to hold at
least three units (except for units held by IRAs and Keogh Plans) following our
acceptance of tendered 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.
 
  Power of Attorney
 
     By executing a Letter of Transmittal, you also irrevocably constitute and
appoint the AIMCO Operating Partnership and its managers and designees as your
attorneys-in-fact, each with full power of substitution, to the full extent of
your rights with respect to the units tendered by you and accepted for payment
by the AIMCO Operating Partnership. Such appointment will be effective when, and
only to the extent that, the AIMCO Operating Partnership accepts the tendered
units for payment. You agree not to exercise any rights pertaining to the
tendered units without the prior consent of the AIMCO Operating Partnership.
Upon such acceptance for payment, all prior powers of attorney granted by you
with respect to such units will, without further action, be revoked, and no
subsequent powers of attorney may be granted (and if granted will not be
effective). Pursuant to such appointment as attorneys-in-fact, the AIMCO
Operating Partnership and its managers and designees each will have the power,
among other things, (i) to transfer ownership of such units on the partnership
books maintained by your general partner (which is our affiliate) (and execute
and deliver any accompanying evidences of transfer and authenticity any of them
may deem necessary or appropriate in connection therewith), (ii) upon receipt by
the Information Agent of the offer consideration, to become a substituted
limited partner, to receive any and all distributions made by your partnership
on or after the date on which the AIMCO Operating Partnership acquires such
units, and to receive all benefits and otherwise exercise all rights of
beneficial ownership of such units in accordance with the terms of our offer,
(iii) to execute and deliver to the general partner of your partnership a change
of address form instructing the general partner to send any and all future
distributions to which the AIMCO Operating Partnership is entitled pursuant to
the terms of the offer in respect of tendered units to the address specified in
such form, and (iv) to endorse any check payable to you or upon your order
representing a distribution to which the AIMCO Operating Partnership is entitled
pursuant to the terms of our offer, in each case, in your name and on your
behalf.

  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."

     The amount of any transfer taxes (whether imposed on the registered holder
of units or any person other than the person signing the Letter of Transmittal)
payable on account of the transfer to such person will be deducted from the
purchase price unless satisfactory evidence of the such taxes or exemption
therefrom is submitted.
 
  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, and
unless units have been accepted for payment as described in "-- Acceptance For
Payment and Payment For Units," tenders of units pursuant to this offer may be
made on or after          , 1999.
 
     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 if any of the conditions to the
offer are not satisfied or if any event occurs that might reasonably be expected
to result in a failure to satisfy such conditions, (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
 
                                      S-36
<PAGE>   42
 
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 7:00 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, Eastern time.
 
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 a majority of the general partner of your partnership
and thereby controls the management of your partnership. In addition, AIMCO owns
a majority of 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
 
                                      S-37
<PAGE>   43
 
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 such as a merger, reorganization or liquidation. We have no present
intention to cause your partnership to sell any of its properties or to prepay
current mortgages 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 or control 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. In addition, we are not extending
appraisal rights in connection with the offer. You have the opportunity to make
your own decision on whether to tender your units in the offer.
 
     No provisions have been made with regard to the offer to allow you or other
limited partners to inspect the books and records of your partnership or to
obtain counsel or appraisal services at our expense or at the expense of your
partnership. However, as described under "Comparison of Your Partnership and the
AIMCO Operating Partnership -- Review of Investor Lists," you have the right
under your partnership's agreement of limited partnership to obtain a list of
the limited partners.
 
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:

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

     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; or

     adverse change in the financial, real
 
                                      S-38

     material adverse change in the commercial mortgage financing markets, (v) a

     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 (any changes to the offer
     resulting from the conditions set forth in this paragraph will most likely
     involve a change in the amount or terms of the consideration offered or the
     termination of the offer); 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, or by
     any other person, before any governmental authority, court or regulatory or
     administrative agency, authority or tribunal, which (i) challenges or seeks
     to challenge the acquisition by the AIMCO Operating Partnership of the
     units, restrains, prohibits or delays the making or consummation of the
     offer, prohibits the performance of any of the contracts or other
     arrangements entered into by the AIMCO Operating Partnership (or any
     affiliates of the AIMCO Operating Partnership) seeks to obtain any material
     amount of damages as a result of the transactions contemplated by the
     offer, (ii) seeks to make the purchase of, or payment for, some or all of
     the units pursuant to the offer illegal or results in a delay in the

     affiliates to conduct your partnership's business or own such assets, (iv)
     seeks to impose material limitations on the ability of the AIMCO Operating
     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
     to vote the units purchased by it on all matters properly presented to
     unitholders or (v) might result, in the sole judgment of the AIMCO
     Operating Partnership, in a diminution in the value of your partnership or
     a limitation of the benefits expected to be derived by the AIMCO Operating
     Partnership as a result of the transactions contemplated by the offer or
     the value of units to the AIMCO Operating Partnership; or
 
        (d) there shall be any action taken, or any statute, rule, regulation,

     (iv) declared or paid any dividend or distribution on any units or issued,
     authorized, recommended or proposed the issuance of any other distribution
     in respect of the units, whether payable in cash, securities or other
     property, (v) authorized, recommended, proposed or announced an agreement,
     or intention to
 
                                      S-39

     enter into an agreement, with respect to any merger, consolidation,
     liquidation or business combination, any acquisition or disposition of a

     consistent with past practice, (viii) authorized, recommended or proposed,
     or entered into, any transaction which, in the sole judgment of the AIMCO
     Operating Partnership, has or could have an adverse affect on the value of
     your partnership or the units, (ix) proposed, adopted or authorized any
     amendment of its organizational documents, (x) agreed in writing or
     otherwise to take any of the foregoing actions, or (xi) been notified 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 (any changes to
     the offer resulting from the conditions set forth in this paragraph will
     most likely involve a change in the amount or terms of the consideration
     offered or the termination of the offer); 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
     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; or
 
        (g) with respect to the cash portion of the offer consideration only,
     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 or may
control such voting decisions. 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 a majority of 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.
 
                                      S-40
<PAGE>   46
 
  Effect on Trading Market; Registration Under Section 12(g) of the Exchange Act
 
     If a substantial number of units are purchased pursuant to the offer, the
result will be a reduction in the number of limited partners in your
partnership. In the case of certain kinds of equity securities, a reduction in
the number of securityholders might be expected to result in a reduction in the
liquidity and volume of activity in the trading market for the security. In this
case, however, there is no established public trading market for the units and,
therefore, the AIMCO Operating Partnership does not believe a reduction in the
number of limited partners will materially further restrict your ability to find
purchasers for your units through secondary market transactions.
 
     The units are registered under Section 12(g) of the Securities Exchange Act
of 1934, which means, among other things, that your partnership is required to
file periodic reports with the SEC and to comply with the SEC's proxy rules. It
is possible that upon consummation of the offer, the units in your partnership
could cease to be registered under Section 12(g) of the Securities Exchange Act
of 1934 (the "Exchange Act") and, your partnership could cease to be required to
file periodic reports under the Exchange Act. If the units were held by fewer
than 300 persons, your partnership could apply to de-register the units under
the Exchange Act. The lack of filing periodic reports could affect the already
limited secondary market which currently exists for units in your partnership
and may result in others not tendering for such units. In such a case, you would
regularly have access only to the limited information your partnership's
agreement of limited partnership requires your general partner (which is our
affiliate) to provide each year, which information consists primarily of tax
information. The AIMCO Operating Partnership will provide to the holders of its
OP Units annual financial statements audited by independent public accountants.
 
  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. See "Your
Partnership -- History of the Partnership."
 
CERTAIN LEGAL MATTERS
 
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by your general partner (which
is our affiliate), 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, other than
the filing with the SEC of a Tender Offer Statement on Schedule 14D-1, a Going
Private Transaction Statement on Schedule 13E-3 and any amendments required
thereto. 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.
 
                                      S-41
<PAGE>   47
 
     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.
 
  Certain Litigation
 
     On March 24, 1998, certain persons claiming to own limited partner
interests in certain of the limited partnerships for which subsidiaries of IPT
act as general partner (including your partnership) filed a purported class and
derivative action in California Superior Court in the County of San Mateo
against AIMCO, Insignia, the general partners of the partnerships, certain
persons and entities who purportedly formerly controlled the general partners,
and additional entities affiliated with and individuals who are officers,
directors and/or principals of several of the defendants. The complaint contains
allegations that, among other things, (i) the defendants breached fiduciary
duties owed to the plaintiffs, or aided and abetted in those purported breaches,
by selling or agreeing to sell their "fiduciary positions" as stockholders,
officers and directors of the general partners for a profit and retaining said
profit rather than distributing it to the plaintiffs; (ii) the defendants
breached fiduciary duties, or aided and abetted in those purported breaches, by
mismanaging the partnerships and misappropriating assets of the partnerships by
(a) manipulating the operations of the partnerships to depress the trading price
of limited partnership units of the Partnerships; (b) coercing and fraudulently
inducing unitholders to sell units to certain of the defendants at depressed
prices; and (c) using the voting control obtained by purchasing units at
depressed prices to entrench certain of the defendants' positions of control
over the partnerships; and (iii) the defendants breached their fiduciary duties
to the plaintiffs by (a) selling assets of the partnerships such as mailing
lists of unitholders and (b) causing the general partners to enter into
exclusive arrangements with their affiliates to sell goods and services to the
general partners, the unitholders and tenants of properties owned by the
partnerships. The complaint also alleges that the foregoing allegations
constitute violations of various California securities, corporate and
partnership statutes, as well as conversion and common law fraud. The complaint
seeks unspecified compensatory and punitive damages, an injunction blocking the
sale of control of the general partners and a court order directing the
defendants to discharge their fiduciary duties to the plaintiffs. On June 25,
1998, the defendants filed motions seeking dismissal of the action. In lieu of
responding to the motion, plaintiffs have filed an amended complaint. On October
14, 1998, the AIMCO and Insignia defendants filed demurrers to the amended
complaint. The demurrers are scheduled to be heard on January 8, 1999.
 
     On July 30, 1998, certain entities claiming to own limited partnership
interests in a number of the limited partnerships for which subsidiaries of IPT
act as general partner (including your partnership) filed a complaint in the
Superior Court of the State of California, County of Los Angeles against
Insignia, the partnerships, the general partners (including your general
partner) and additional entities affiliated with several of the defendants.
Plaintiffs allege that they have requested from, but have been denied by each of
the partnerships, lists of their respective limited partners for the purpose of
making tender offers to purchase up to 4.9% of the units of limited partnership
interest in each of the partnerships. The complaint also alleges that certain of
the defendants made tender offers to purchase units of limited partnership
interest in many of the partnerships, with the alleged result that plaintiffs
have been deprived of the benefits they would have realized from ownership of
the additional units. The plaintiffs assert eleven causes of action, including
breach

of contract, unfair business practices, and violations of the partnership
statutes of the states in which the partnerships are organized. Plaintiffs seeks
compensatory, punitive and treble damages. Plaintiffs estimate compensatory
damages to exceed $15 million. An answer to the complaint was filed by the
defendants on September 15, 1998.
 
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 $50,000.
 
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.

                       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 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. Further, no opinion of tax counsel has been obtained with regard to
the offer. However, an opinion of counsel has been obtained with regard to
AIMCO's status as a REIT and that the OP Units will be validly issued, fully
paid and non-assessable. You may obtain a copy of such opinion by sending a
written request to the AIMCO Operating Partnership.
 
     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
 
                                      S-44
<PAGE>   50
 
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 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
 
                                      S-45
<PAGE>   51
 
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 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. You will not receive any future distributions on units that you tender on
or after the date on which such units are accepted for purchase, and
accordingly, you may not receive any distributions with respect to such accreted
income. 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 OFFEREES
 
     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 offerees who do not tender all of their units (a "Remaining Offeree") in
proportion to their respective interests in the Old Partnership in liquidation
of the Old Partnership.
 
     A Remaining Offeree will not recognize any gain or loss upon the
Hypothetical Distribution or upon the Hypothetical Contribution and the capital
accounts of the Remaining Offerees in the Old Partnership will carry over intact
into the New Partnership. Any Termination may change (and possibly shorten) a
Remaining Offeree'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 Offerees 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 Offerees 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 offeree 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 offerees. In the case of a Remaining Offeree 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 Offeree'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 value of each
property owned by your partnership using the direct capitalization method. This
method involves applying a capitalization rate to the property's annual net
operating income. We determined appropriate capitalization rates, but our
valuation is just an estimate. In estimating the capitalization rates, we
considered the property's physical condition, location and above-market mortgage
interest rates. In addition, we considered the recent decline in the real estate
markets, and the decline in the availability of commercial mortgage financing
and the recent bankruptcy of a major provider of subordinated 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 a 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 estimated the value of the property owned by your partnership
       using the direct capitalization method. We selected capitalization rates
       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 each 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 divided each
       property's fiscal 1997 net operating income by its capitalization rate to
       derive an estimated gross property value as described in the following
       table:

     - Second, we calculated the value of the equity of your partnership by
       adding to the aggregate gross property value of all properties owned by
       your partnership, 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 $25,265,202.

<PAGE>   54
 
     - 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 AIMCO Operating Partnership has a majority ownership interest in the
general partner of your partnership. Therefore, the general partner of your
partnership makes no recommendation whether you should tender or refrain from
tendering your units since it did not participate in the structuring of the
offer and has substantial conflicts of interest with regard to the offer.
However, for all of the reasons discussed herein, we and your general partner
believe that the offer is fair to you and the other holders of units in your
partnership. We also reasonably believe that the similar offers to the limited
partners of the other partnerships are fair to such limited partners. 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, your
general partner (which is our affiliate) 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 properties 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 are substantially the financial
     equivalent to your interest in your partnership, adjusted to reflect the
     expenses of the offer. See "Valuation of Units."
 
        6. The opinion of Stanger, an independent third party, 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 generally 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 by electing to accept Preferred OP Units or
     Common OP Units.
 
        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 $505.00, based on a total estimated
     value of your partnership's properties of $51,991,000. Your general partner
     (which is our affiliate) has no present intention to liquidate your
 
                                      S-50
<PAGE>   56
 
     partnership or to sell or refinance your partnership's properties. See
     "Background and Reasons for the Offer".
 
        12. Anticipated annualized distributions with respect to the Preferred
     OP Units are $2.00 and current annualized distributions with respect to the
     Common OP Units are $2.25. This is equivalent to distributions of $40.40
     per year on the number of Preferred OP Units, or distributions of $
     per year on the number of Common OP Units, that you would receive in
     exchange for each of your partnership's units. Distributions with respect
     to your units for the nine months ended September 30, 1998 were $16.07. See
     "Comparison of Ownership of Your Units and AIMCO OP Units --
     Distributions."
 
        13. The offer consideration in light of any previous tender offers and
     the results of such offers. See "Background and Reasons for the
     Offer -- Background of the Offer -- Previous Tender Offers" and "Your
     Partnership -- Beneficial Ownership of Interests in Your Partnership."
 
     In evaluating these factors, your general partner (which is our affiliate)
and the AIMCO Operating Partnership did not quantify or otherwise attach
particular weight to any of them.
 
     Your general partner (which is our affiliate) has not retained an
unaffiliated representative to act on behalf of the limited partners in
negotiating the terms of the offer since each individual limited partner can
make his own decision as to whether or not to tender and what consideration to
take. Unlike a merger or other form of partnership reorganization, a majority or
more of the holders of limited partnership interests in your partnership cannot
bind you. If an unaffiliated representative had been obtained, it is possible
that such representative could have negotiated a higher price for your units
than was unilaterally offered by the AIMCO Operating Partnership. We have
retained Stanger to conduct an analysis of our offer and to render an opinion as
to the fairness to you of the offer consideration from a financial point of
view.
 
FAIRNESS TO UNITHOLDERS WHO TENDER THEIR UNITS
 
     Your general partner (which is our affiliate) 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 and, although there are
other ways to value real estate, is a reasonably fair method to determine the
consideration offered. A liquidation in the future might generate a higher or
lower 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
 
     Your general partner (which is our affiliate) 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, your general partner
(which is our affiliate) 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 your general partner (which is our affiliate). 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 your general partner (which is our affiliate) 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
 
     Secondary market sales activity for the units, including privately
negotiated sales, has been limited and sporadic. According to information
obtained from your general partner (which is our affiliate) from November 1,
1995 to July 31, 1998 an aggregate of 1,419 units (representing approximately
2.8% of the total outstanding units) was transferred (excluding units
transferred by Insignia to IPLP in February 1998 and in tender offers) in sale
transactions. Set forth in the table below are the high and low sales prices of
units for the quarterly periods from November 1, 1995 to July 31, 1998, as
reported by your general partner and by The Partnership Spectrum, which is an
independent, third-party source. The gross sales prices reported by The
Partnership Spectrum do not necessarily reflect the net sales proceeds received
by sellers of units, which typically are reduced by commissions and other
secondary market transaction costs to amounts less than the reported prices;
thus the AIMCO Operating Partnership does not know whether the information
compiled by The Partnership Spectrum is accurate or complete. The transfer
paperwork submitted to the general partner often does not include the requested
price information or contains conflicting information as to the actual sales
price. Accordingly, you should not rely upon this information as being
completely accurate.

(a)  Although the general partner requests and records information on the prices
     at which units are sold, it does not regularly receive or maintain
     information regarding the bid or asked quotations of secondary market
     makers, if any. The general partner processes transfers of units only 12
     times per year -- on the first day of each month. The prices in the table
     are based solely on information provided to the general partner by sellers
     and buyers of units transferred in sale transactions (i.e., excluding
     transactions believed to result from the death of a limited partner,
     rollover to an IRA account, establishment of a trust, trustee to trustee
     transfers, termination of a benefit plan, distributions from a qualified or
     non-qualified plan, uniform gifts, abandonment of units or similar non-sale
     transactions).
 
(b)  The gross sales prices reported by The Partnership Spectrum do not
     necessarily reflect the net sales proceeds received by sellers of units,
     which typically are reduced by commissions and other secondary market
     transaction costs to amounts less than the reported prices. The AIMCO
     Operating Partnership does not know whether the information compiled by The
     Partnership Spectrum is accurate or complete.
 
(c)  Information not yet published.
 
     The AIMCO Operating Partnership believes that, although secondary market
sales information probably is not a reliable measure of value because of the
limited and inefficient nature of the market for units, this information may be
relevant to a limited partner's decision as to whether to tender his or her
units pursuant to the offer. At present, privately negotiated sales and sales
through intermediaries (e.g., through the trading system operated by American
Partnership Board, Inc., which publishes sell offers by holders of units) are
the only means available to a limited partner to liquidate an investment in
units (other than the offer) because the units are not listed or traded on any
exchange or quoted on NASDAQ.
 
  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. Your general
partner (which is our affiliate) 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
liquidation analysis also assumed that your partnership's property was sold to
an independent third-party buyer
 
                                      S-53
<PAGE>   59
 
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.
 
     In estimating the net liquidation proceeds, your general partner (which is
our affiliate) considered, among other things, the following valuations:
 
     Appraisals. Each of your partnership's properties was appraised in 1997 by
an independent third party appraiser, Koeppel Tener Real Estate Services, Inc.
(the "Appraiser"), in connection with a requirement in your partnership's
agreement of limited partnership and not in connection with the offer. According
to the appraisal reports, the scope of the appraisals included an inspection of
each property and an analysis of the surrounding market. The Appraiser relied
principally on the income capitalization approach to valuation and secondarily
on the sales comparison approach, and represented that its report was prepared
in accordance with the Code of Professional Ethics and Standards of Professional
Appraisal Practice of the Appraisal Institute and the Uniform Standards of
Professional Appraisal Practice, and in compliance with the Appraisal Standards
set forth in the Financial Institutions Reform, Recovery and Enforcement Act of
1989 (known as "FIRREA"). The estimated market value of the fee simple estate of
each of the properties specified in those reports was $32,000,000 for Baymeadows
Apartments; $12,700,000 for Quail Run Apartments; and $14,300,000 for
Countrywood Village Apartments. Such appraisals do not reflect the mortgages
encumbering the properties or any costs of sales of the properties. A copy of
the summaries of the appraisals has been filed as an exhibit to the Tender Offer
Statement on Schedule 14D-1 filed with the SEC by Cooper River Properties,
L.L.C. (which is now our affiliate). We also believe that based on the
conditions of the properties, the appraisals substantially overstate their
value. For instance, we have received a report from an independent third party
that there is a total of approximately $4,400,000 of deferred maintenance costs
at all three properties. Such maintenance costs consist primarily of repairs
outside the buildings and new roofing. Therefore, we believe that the appraisals
are less meaningful in determining the offer consideration than the analysis
described above under "Valuation of Units." Such appraisals are not intended to
be updated.
 
     General Partner's Annual Estimates of Net Asset Value. Your general partner
(which is our affiliate) prepared an estimate of your partnership's net asset
value per unit in connection with an offer to purchase up to 4.9% of the
outstanding units commenced by an unaffiliated party in September 1998. That
estimate of your partnership's net asset value per unit as of October 31, 1997
was $715.00. This estimated net asset value is based on a hypothetical sale of
the partnership's properties and the distribution to the limited partners and
the general partner of the gross proceeds of such sales, net of related
indebtedness, together with the cash, proceeds from temporary investments, and
all other assets that are believed to have liquidation value, after provision in
full for all of the other known liabilities of your partnership. This net asset
value does not take into account (i) timing considerations, (ii) costs
associated with winding up the partnership, (iii) the distribution paid by your
partnership of $16.07 per unit for the nine months ended July 31, 1998, or (iv)
the anticipated distribution expected to be paid by your partnership in December
1998 of approximately $48 per unit. Therefore, the AIMCO Operating Partnership
believes that this estimate of net asset value per unit does not necessarily
represent either the fair market value of a unit or the amount a limited partner
reasonably could expect to receive if the partnership's properties were sold and
the partnership was liquidated. For this reason, the AIMCO Operating Partnership
considered this net asset value estimate to be less meaningful in determining
the offer consideration than the analysis described above under "Valuation of
Units."

ALLOCATION OF CONSIDERATION
 
     We have allocated the estimated liquidation proceeds in accordance with the
liquidation provisions of your partnership agreement of limited partnership.
Accordingly, 100% 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 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 "-- 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.
 
EXPERIENCE OF STANGER
 
     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 NYSE 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

     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. Stanger was selected because of its experience and reputation in
connection with real estate partnerships, real estate assets and mergers and
acquisitions.
 
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 annual reports on Form 10-KSB filed with the SEC for the years
ending December 31, 1996 and 1997, and the quarterly report on Form 10-QSB for
the period ending July 31, 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 real estate assets (the
"property") provided by
 
                                      S-55
<PAGE>   61
 
management, including location, number of units and unit mix or square footage,
age, and amenities; (iv) reviewed summary historical operating statements for
your partnership's property for 1996 and 1997 and through July 31, 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 similar properties in the
general market area of your partnership's property and other information
relating to acquisition criteria for similar 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; (x) reviewed available secondary
market trading information for the units; and (xi) 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 the property, 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 site inspections 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 October and November 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 or
square footage; 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 nine month period ending July
31, 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. Stanger has rendered similar fairness opinions with regard to certain
other exchange offers being made by the AIMCO Operating Partnership. Stanger
rendered the opinions only as to the individual fairness of the offer
consideration in each proposed exchange offer.
 
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 your general partner (which is our affiliate), 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,
 
                                      S-57

and adjustments to the offer consideration for distributions made by your
partnership subsequent to the date of the offer.
 
     Stanger is not expressing any opinions as to the fairness of any terms of
the offer other than the offer consideration for the units. 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.
 
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 $17,000 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.

                       DESCRIPTION OF PREFERRED OP UNITS
 
GENERAL
 
     The Preferred OP Units are the Class I 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 Class I High Performance 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, the Class J 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 $0.50 per Preferred OP
Unit (equivalent to 8.0% per annum of the $25 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. A reduction in the
distribution rate will reduce your rate of return on the Preferred OP Units and
possibly encourage you to redeem such Units. 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
 
                                      S-73
<PAGE>   79
 
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 $25 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 allocation of income or gain. 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
 
                                      S-74
<PAGE>   80
 
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 NYSE 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, the Class J 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 8.0% per annum of the $25 liquidation preference (equivalent to
$2.00 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
 
                                      S-76
<PAGE>   82
 
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.

                             CONFLICTS OF INTEREST
 
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
 
     The general partner of your partnership became a majority-owned 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 have a majority ownership interest in both the general partner of your
partnership and the manager of your partnership's property. The general partner
does not receive an annual management fee but may receive reimbursements for
expenses incurred in its capacity as general partner. The general partner of
your partnership received total fees and reimbursements of $196,000 in 1996,
$223,000 in 1997 and $158,000 for the nine months ended July 31, 1998. The
property manager received management fees of $540,000 in 1996, $558,000 in 1997
and $430,000 for the nine months ended July 31, 1998. The AIMCO Operating
Partnership has no current intention of changing the fee structure for the
general partner or 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 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
 
     Shelter Properties IV was organized on August 21, 1981, under the laws of
the State of South Carolina. Its primary business is real estate ownership and
related operations. Your partnership was formed for the purpose of making
investments in various types of real properties which offer potential capital
appreciation and cash distributions to its limited partners. Your partnership's
investment portfolio currently consists of the following three residential
apartment complexes: Baymeadows Apartments, a 904-unit complex in Jacksonville,
Florida; Quail Run Apartments, a 332-unit complex in Columbia, South Carolina;
and Countrywood Village Apartments, a 384-unit complex in Raleigh, North
Carolina. The general partner of your partnership is Shelter Realty IV
Corporation, which is a majority-owned subsidiary of AIMCO. A majority-owned
subsidiary of AIMCO serves as manager of the properties owned by your
partnership. As of September 15, 1998, there were 49,995 units of limited
partnership interest issued and outstanding, which were held of record by 3,676
limited partners. Your partnership's principal executive offices are located at
1873 South Bellaire Street, 17th Floor, Denver, Colorado 80222, and its
telephone number at that address is (303) 757-8101. For additional information
about your partnership, please refer to the annual and quarterly reports
prepared by your partnership which accompany this Prospectus Supplement.
 
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."
 
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.

reports described above.
 
HISTORY OF THE PARTNERSHIP
 
     Your partnership sold $40,000,000 of limited partnership units in 1982 for
$1,000.00 per unit. Between November 1, 1992 and July 31, 1998 your partnership
made a total of $53.80 of distributions per unit.
 
     Your partnership raised proceeds to purchase certain properties and it has
expended the funds so raised many years ago. Your partnership currently owns the
properties described herein, each of which is subject to a substantial mortgage.
Your general partner (which is our affiliate) has not experienced any material
adverse financial developments from January 1, 1997 through the present.
 
     According to the prospectus dated June 8, 1982, by which units in your
partnership were originally offered, the general partner of your partnership
(which at the time was not affiliated with AIMCO) indicated that prior
partnerships sponsored by affiliates of the general partner had, on average,
begun selling their properties during the third year after the investments were
made and had sold all of their properties after eight years of ownership. The
prospectus further stated, however, that the general partner was unable to
predict how long the partnership would remain invested in the properties and
that the partnership acquired such properties for investment rather than resale.
In any event, according to the prospectus, the general partner anticipated that
a disposition of the properties would depend on, among other things, the current
real estate and money markets, economic climate and income tax consequences to
the limited partners. We do not know why your partnership did not sell all of
its properties within such holding period. Under your partnership's agreement of
limited partnership, the term of the partnership will continue until December
31, 2022, unless sooner terminated as provided in the agreement or by law.
Limited partners could, as an alternative to tendering their units, take a
variety of possible actions, including voting to liquidate the partnership or
amending the agreement of limited partnership to authorize limited partners to
cause the partnership to merge with another entity or engage in a "roll-up" or
similar transaction.
 
     Consummation of the offer will not affect your partnership's agreement of
limited partnership, the financial condition or results of operations of your
partnership, the business and properties owned, the distributions and
compensation payable to your general partner (which is our affiliate) or its
affiliates or any other matter relating to your partnership, except it would
result in the AIMCO Operating Partnership substantially increasing its ownership
of units of your partnership. It is possible that after the consummation of the
offer, the AIMCO Operating Partnership could, as a practical matter, control any
vote of the limited partners. Further, we will be able to receive any future
distributions from your partnership for any units we purchase.
 
GENERAL POLICY REGARDING SALES AND REFINANCINGS OF PARTNERSHIP PROPERTIES
 
     In general, your general partner (which is our affiliate) regularly
evaluates the partnership's properties by considering various factors, such as
the partnership's financial position and real estate and capital markets
conditions. The general partner monitors each property's specific locale and
sub-market conditions evaluating current trends, competition, new construction
and economic changes. The general partner oversees each asset's operating
performance and continuously evaluates the physical improvement requirements. In
addition, the financing structure for each property, tax implications and the
investment climate are all considered. Any of these factors, and possibly
others, could potentially contribute to any decision by the general partner to
sell, refinance, upgrade with capital improvements or hold a particular
partnership property. Based on the above considerations, the general partner has
determined that it is not in the best interests of limited partners to sell or
refinance any property at the present time. For a description of mortgages, see
the reports described under "Your Partnership -- Additional Information
Concerning Your Partnership," which are incorporated by reference and are
considered part of this Prospectus Supplement.

PROPERTY MANAGEMENT
 
     Your partnership's property is managed by an entity which is a
majority-owned subsidiary 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.
 
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
 
     Under applicable law, your general partner (which is our affiliate) is
accountable to your partnership as a fiduciary. Under your partnership's
agreement of limited partnership, the general partner is not liable to your
partnership or the limited partners for any act or failure to act if such act or
failure to act was performed in a manner determined by him or it in good faith
to be within the scope of his or its authority and to be in the best interest of
your partnership, and if he or it was not guilty of negligence, misconduct or a
breach of fiduciary obligations in such act or failure to act. 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
majority-owned by AIMCO. See "Conflicts of Interest".
 
     Under your partnership's agreement of limited partnership, your partnership
will indemnify the general partner and any of its affiliates or your
partnership's employees, against any claim or liability by or to any person
other than your partnership, for any act or failure to act if such act or
failure to act was performed in a manner determined by him or it in good faith
to be within the scope of his or its authority and to be in the best interest of
your partnership, and if he or it was not guilty of negligence, misconduct or a
breach of fiduciary obligations in such act or failure to act, provided however,
that your partnership will not furnish any indemnification as to liabilities
arising under federal securities laws. The indemnification includes payment of
reasonable attorney's fees or other expenses incurred in settling any claim or
liability or incurred in any finally adjudicated judicial proceedings, and
expenses incurred by the removal of any liens affecting any property of the
person to be indemnified. Indemnification will be made from assets of your
partnership and no limited partner will be personally liable to any person to be
indemnified.
 
     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.

             SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
 
     The AIMCO Operating Partnership expects that approximately $15,300,000 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. The AIMCO
Operating Partnership will pay all of the costs of the offer and not your
partnership.
 
     Below is an itemized statement of the estimated expenses incurred and to be
incurred in the offer by the AIMCO Operating Partnership:

     If funds are borrowed to consummate the offer, we intend to use our amended
and restated credit agreement with Bank of America National Trust and Savings
Association ("Bank of America") and BankBoston, N.A. The credit agreement
provides a revolving credit facility of up to $100 million, including a swing
line of up to $30 million. The AIMCO Operating Partnership is the borrower under
the credit facility, and all obligations thereunder are guaranteed by AIMCO and
certain of its subsidiaries. The annual interest
 
                                      S-86
<PAGE>   92
 
rate under the credit facility is based on either LIBOR or a base rate which is
the higher of Bank of America's reference rate or 0.5% over the federal funds
rate, plus, in either case, an applicable margin. The AIMCO Operating
Partnership elects which interest rate will be applicable to particular
borrowings under the credit facility. The margin ranges between 1.25% and 2.0%
in the case of LIBOR-based loans and between negative 0.25% and positive 0.5% in
the case of base rate loans, depending upon a ratio of the AIMCO Operating
Partnership's consolidated unsecured indebtedness to the value of certain
unencumbered assets. The credit facility matures on September 30, 1999 unless
extended, at the discretion of the lenders. The credit facility provides for the
conversion of the revolving facility into a three year term loan. The
availability of funds to the AIMCO Operating Partnership under the credit
facility is subject to certain borrowing base restrictions and other customary
restrictions, including compliance with financial and other covenants
thereunder. The financial covenants require the AIMCO Operating Partnership to
maintain a ratio of debt to gross asset value of no more than 0.55 to 1.0, an
interest coverage ratio of 2.25 to 1.0 and a fixed charge coverage ratio of at
least 1.6 to 1.0 through December 31, 1998, 1.7 to 1.0 from January 1, 1999
through June 30, 1999, and 1.8 to 1.0 thereafter. In addition, the credit
facility limits the AIMCO Operating Partnership from distributing more than 80%
of its Funds From Operations (as defined) to holders of OP Units, imposes
minimum net worth requirements and provides other financial covenants related to
certain unencumbered assets.
 
     Following the IPT merger, we may obtain funds pursuant to a credit
agreement entered into by Insignia Properties, L.P. ("IPLP"), the operating
partnership for IPT, with Lehman Commercial Paper, Inc., as syndication agent,
First Union National Bank, as administrative agent and the lenders from time to
time parties thereto. Pursuant to the credit agreement, which is guaranteed by
IPT, the lenders have made available to IPLP a revolving credit facility of up
to $50,000,000 at any one time outstanding which matures in a single installment
on December 30, 2000. Loans may be borrowed by IPLP at a rate based upon the
adjusted LIBOR Rate (as defined in the credit agreement) or the Base Rate (as
defined in the credit agreement). IPT is obligated to pay a commitment fee at a
rate of 0.25% per annum on the undrawn portion of the line of credit. The credit
agreement includes customary covenants and restrictions on IPLP's ability to,
among other things, incur debt or contingent obligations, grant liens, sell
assets, make distributions or make investments. In addition, the credit
agreement contains certain financial covenants. The AIMCO Operating Partnership
intends to repay any funds borrowed out of working capital in the ordinary
course of business.

AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  Shelter Properties IV
 
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
Shelter Properties IV (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

     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

located throughout the United States, including major New York Stock Exchange

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
     October 31, 1995, 1996 and 1997, and annual reports on Form 10-KSB filed
     with the Securities and Exchange Commission for the years ended October 31,
     1996 and 1997, and quarterly report on Form 10-QSB for the period ending
     July 31, 1998, which the Partnership's management has indicated to be the
     most current available financial statements;
 
          3. Reviewed descriptive information concerning the real property owned
     by the Partnership (the "Property"), including location, number of units
     and unit mix, age, amenities and land acreage;

<PAGE>   94
 
          4. Reviewed summary historical operating statements for the Property,
     for the years ended October 31, 1996 and 1997, and the nine months ending
     July 31, 1998;
 
          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

          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 Properties or the sale or
transfer of a material amount of the Partnership's other assets; any
                                       A-2
<PAGE>   95
 
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,

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>   103
 
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;
 
                                      II-4
<PAGE>   106
 
             (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 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.
