INTRODUCTION

           The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements in certain circumstances. Certain
information included in this Report and other Partnership filings (collectively
"SEC Filings") under the Securities Act of 1933, as amended, and the Securities
Exchange Act of 1934, as amended (as well as information communicated orally or
in writing between the dates of such SEC Filings) contains or may contain
information that is forward looking, including statements regarding the effect
of government regulations. Actual results may differ materially from those
described in the forward looking statements and will be affected by a variety of
factors including national and local economic conditions, the general level of
interest rates, terms of governmental regulations that affect the Partnership
and interpretations of those regulations, the competitive environment in which
the properties owned by the Local Limited Partnerships operate, the availability
of working capital and dispositions of properties owned by the Partnership.

Item 1.    Business

           National Housing Partnership Realty Fund IV, a Maryland Limited
Partnership (the Partnership), was formed under the Maryland Revised Uniform
Limited Partnership Act as of January 8, 1986. On January 15, 1986, the
Partnership commenced offering 35,000 limited partnership interests, at a price
of $1,000 per interest, through a public offering registered with the Securities
and Exchange Commission (the Offering). The Offering was managed by Dean Witter
Reynolds, Inc. and was terminated on October 14, 1986, with subscriptions for
15,414 limited partnership interests.

           On June 3, 1997, Apartment Investment and Management Company, a
Maryland corporation ("AIMCO" and, together with its subsidiaries and other
controlled entities, the "AIMCO Group"), acquired all of the issued and
outstanding capital stock of NHP Partners, Inc., a Delaware corporation ("NHP
Partners"), and the AIMCO Group acquired all of the outstanding interests in NHP
Partners Two Limited Partnership, a Delaware limited partnership ("NHP Partners
Two"). The acquisitions were made pursuant to a Real Estate Acquisition
Agreement, dated as of May 22, 1997 (the "Agreement"), by and among AIMCO, AIMCO
Properties, L.P., a Delaware limited partnership (the "Operating Partnership"),
Demeter Holdings Corporation, a Massachusetts corporation ("Demeter"), Phemus
Corporation, a Massachusetts corporation ("Phemus"), Capricorn Investors, L.P.,
a Delaware limited partnership ("Capricorn"), J. Roderick Heller, III and NHP
Partners Two LLC, a Delaware limited liability company ("NHP Partners Two LLC").
NHP Partners owns all of the outstanding capital stock of the National
Corporation for Housing Partnerships, a District of Columbia corporation
("NCHP"), which is the general partner of The National Housing Partnership, a
District of Columbia limited partnership ("NHP"). Together, NCHP and NHP
Partners Two own all of the outstanding partnership interests in NHP. NHP is the
general partner of National Housing Partnership Realty Fund IV (a Maryland
Limited Partnership) (the "Registrant" or "Partnership"). As a result of these
transactions, the AIMCO Group has acquired control of the general partner of the
Registrant and, therefore, may be deemed to have acquired control of the
Registrant.

           The Original Limited Partner of the Partnership is 1133 Fifteenth
Street Four Associates, a Maryland limited partnership, whose general partner is
NHP and whose limited partners were key employees of NCHP at the time the
Partnership was formed. The Original Limited Partner holds a 1% Limited
Partnership interest in the Partnership.

           The remaining 98% limited partnership interests in the Partnership
are held by the investors who subscribed to the Offering.

           In October 1997, NHP received a subpoena from the Inspector General
of the United States Department of Housing and Urban Development ("HUD")
requesting documents relating to any arrangement whereby NHP or any of its
affiliates provides or has provided compensation to owners of HUD multifamily
projects in exchange for in connection with property management of a HUD
project.  AIMCO believes that other owners and managers of HUD projects have
received similar subpoenas. Documents relating to certain of NHP's aquisitions
of property management rights for HUD projects may be responsive to subpoenas. 
AIMCO and NHP are in the process of complying with the subpoena and have
provided certain documents to the Inspector General, without conceding that
they are responsive to the subpoena.  AIMCO believes that NHP's operations are
in compliance, in all material respects, with all laws, rules and regulations
relating to HUD-assisted or HUD-insured properties. Effective February 13,
1998, counsel for NHP and the U.S. Attorney for the Northern District of
California entered into a Tolling agreement related to certain civil claims the
government may have against NHP.  Although no action has been initiated against
NHP or AIMCO or, to AIMCO's knowledge, any owner of a HUD property managed by
NHP or AIMCO, if any such action is taken in the future, it could ultimately
affect existing arrangements with respect to HUD projects or otherwise have a
material adverse affect on the results of operations of AIMCO. 

           The Partnership's business is to own directly one multi-family
housing property, Trinity Apartments, and to hold limited partnership interests
in four limited partnerships (Local Limited Partnerships), which in turn, owns
and operates multi-family rental housing properties (Properties). With the
exception of Trinity Apartments, all of these Properties receive one or more
forms of assistance from the Federal Government.


                                       2
<PAGE>   4


           The Partnership acquired the interests in the four Local Limited
Partnerships from sellers who originally developed the Properties. The
Partnership directly purchased Trinity Apartments. With respect to the Local
Limited Partnerships, NHP is the general partner of each Local Limited
Partnership and the Partnership is the principal limited partner. As a limited
partner, the Partnership's liability for obligations of the Local Limited
Partnerships is limited to its investment, and the Partnership does not exercise
control over the activities of the Local Limited Partnerships in accordance with
the partnership agreements.

           The Partnership's investment objectives are to:

           (1)       preserve and protect Partnership capital;

           (2)       provide current tax benefits to Limited Partners to the
                     extent permitted by law, including, but not limited to,
                     deductions that Limited Partners may use to offset
                     otherwise taxable income from other sources;

           (3)       provide capital appreciation through increase in value of
                     the Partnership's investments, subject to considerations of
                     capital preservation and tax planning; and

           (4)       provide potential cash distributions from sales or
                     refinancings of the Partnership's investments and, on a
                     limited basis, from operations.

           The Partnership does not have any employees. Services are performed
for the Partnership by the General Partner and agents retained by it.

           The following is a schedule of the Properties owned directly by the
Partnership or by the Local Limited Partnerships in which the Partnership is a
limited partner:

(B)        The mortgage is insured by the Federal Housing Administration under
           the provisions of Section 221(d)(3) of the National Housing Act.

(C)        Property is conventionally financed.

(D)        Section 8 of Title II of the Housing and Community Development Act of
           1974.

           Although each Local Limited Partnership in which the Partnership has
invested owns an apartment complex which must compete with other apartment
complexes for tenants, government mortgage interest and rent subsidies make it
possible to rent units to eligible tenants at below market rates. In general,
this insulates the Properties from market competition.

           The Federal Housing Administration (FHA) has contracted with the four
subsidized rental projects under Section 8 of Title II of the Housing and
Community Development Act of 1974 to make housing assistance payments to the
Local Limited Partnerships on behalf of qualified tenants. The terms of the
agreements are five years with one or two five year renewal options. The
agreements expire at various dates ranging from 1998 to 2008 as follows:

           The following table indicates the year within the Section 8 rent
subsidy contracts expire:

           Of the contracts above expiring during 1998, contracts for 496 units
expire on or prior to September 30, 1998. Congress has passed legislation which
will provide a one-year renewal contract to replace those contracts. The
contract covering the remaining 123 units expires in October, 1998. It is
uncertain whether the agreement will be renewed, as well as the remaining
contracts expiring after 1998, and if so, on what terms.

           For the past several years, various proposals have been advanced by
the United States Department of Housing and Urban Development ("HUD"), Congress
and others proposing the restructuring of HUD's rental assistance programs under
Section 8 of the United States Housing Act of 1937 ("Section 8"), under which
896 units, 97 percent of the total units owned by the properties in which the
Partnership has invested (excluding Trinity Apartments), receive rental
subsidies. On October 27, 1997, the President signed into law the Multifamily
Assisted


                                        4
<PAGE>   6


Housing Reform and Affordability Act of 1997 (the "1997 Housing Act"). Under the
1997 Housing Act, certain properties assisted under Section 8, with rents above
market levels and financed with HUD-insured mortgage loans, will be restructured
by adjusting subsidized rents to market levels, thereby potentially reducing
rent subsidies, and lowering required debt service costs as needed to ensure
financial viability at the reduced rents and rent subsidies. The 1997 Housing
Act retains project-based subsidies for most properties (properties in rental
markets with limited supply, properties serving the elderly, and certain other
properties). The 1997 Housing Act phases out project-based subsidies on selected
properties servicing families not located in rental markets with limited supply,
converting such subsidies to a tenant-based subsidy. Under a tenant-based
system, rent vouchers would be issued to qualified tenants who then could elect
to reside at properties of their choice, provided such tenants have the
financial ability to pay the difference between the selected properties' monthly
rent and the value of the vouchers, which would be established based on HUD's
regulated fair market rent for the relevant geographical areas. The 1997 Housing
Act provides that properties will begin the restructuring process in federal
fiscal year 1999 (beginning October 1, 1998), and that HUD will issue final
regulations implementing 1997 Housing Act on or before October 27, 1998. With
respect to Housing Assistance Payments Contracts ("HAP Contracts") expiring
before October 1, 1998, Congress has elected to renew them for one-year terms,
generally at existing rents, so long as the properties remain in compliance with
the HAP Contracts. While the Partnership does not expect the provisions of the
1997 Housing Act to result in a significant number of tenants relocating from
properties owned by the Local Limited Partnerships, there can be no assurance
that the provisions will not significantly affect the operations of the
properties of the Local Limited Partnerships. Furthermore, there can be no
assurance that other changes in Federal housing subsidy policy will not occur.
Any such changes could have an adverse effect on the operation of the
Partnership.

           Trinity Apartments (Trinity), which is wholly-owned by the
Partnership, is conventionally financed and is a market rate project which
receives no government assistance and must compete directly with other apartment
complexes in its rental market. The local economy and competitive conditions in
the Dallas area, historically, have adversely affected operations at Trinity
Apartments.

           The mortgage note payable on Trinity provided by General Electric
Capital Corporation ("GECC") was due June 30, 1995. On March 15, 1996, a
modification agreement to the mortgage agreement was signed which, among other
provisions, extended the due date to March 15, 1999. As a condition of the
modification, a principal payment of $560,000 was made to reduce the mortgage
note payable to $13,140,000. In order to make the required payment and to pay
additional financing fees, the General Partner made a loan of $667,202 to
Trinity. On December 29,1997, Trinity refinanced the mortgage note payable. GECC
was paid $13,093,546 to pay off the note along with a $1,300,000 prepayment
penalty representing 50% of the fair market value of the project above the
amount of refinanced debt as required under the GECC mortgage agreement.
Proceeds from the refinancing along with a loan of $6,121,479 from an affiliate
of the General Partner, AIMCO Properties L.P., were used to retire the existing
mortgage note, pay the prepayment penalty of $1,300,000 and to pay accrued
interest and other deferred finance costs of $925,930. The new mortgage note
payable of $9,620,000 is held by Lehman Capital and is secured by a deed of
trust on the rental property and an assignment of all right of title and
interest in, leases with the tenants. The note bears interest at the rate of
6.557% per annum. The principal and interest are payable by Trinity in equal
monthly installments of $84,102 to December 1, 2012.

           The General Partner has made substantial loans to Trinity. During
1996, Trinity made payments to the General Partner for principal and interest of
$5,764 and $438, respectively. Given the competitive nature of the Dallas
market, it is still uncertain as to whether the property will continue to
generate sufficient cash flow to repay the remaining loans and interest to the
General Partner.

           On December 1, 1996, a fire occurred at the Royal Towers Limited
Partnership project site. Management believes that all damages will be recovered
through insurance proceeds less a $2,500 deductible. As of December 31, 1996, an
insurance receivable was recorded for $1,880,289 which included $1,784,685 for
fire loss damages net of the deductible, and $95,604 for loss of rent for the
month of December, 1996.

           During 1997, Royal Towers Limited Partnership received approximately
$2,756,000 in insurance proceeds relating to the fire and used approximately
$2,485,000 of these proceeds as of December 31, 1997, to repair the damages. Use
of the remaining $271,000 held in escrow by the mortgage company and the final
insurance award have


                                       5
<PAGE>   7


not been determined or approved. During 1997, HUD approved withdrawals of
$249,365 from the reserve for replacements to pay outstanding fire related
payables. This is considered a loan from the reserve for replacements and must
be repaid to the reserve for replacements when reimbursement is received from
the insurance company.

           In addition to amounts reimbursed from insurance proceeds, Royal
Towers Limited Partnership has incurred costs of $190,761 which are fire related
and have been included in the accompanying combined statements of operations and
$95,164 of costs which have been capitalized. Royal Towers Limited Partnership
anticipates that an additional $1,000,000 is needed to repair the property to
its pre-fire condition and is seeking insurance funds to cover such costs.

           During 1996, NHPMC, an affiliate of the General Partner, was
management agent under an agreement which ended on October 31,1996. At December
31, 1996, the Royal Towers Limited Partnership had accrued costs due to NHPMC
consisting of management fees, bookkeeping and accounting fees, payroll and
miscellaneous reimbursement items totaling $167,762. During 1997, NHPMC informed
Royal Towers Limited Partnership that these amounts totaling $167,762 do not
have to be paid and therefore this amount is shown as an extraordinary gain in
the accompanying 1997 combined statements of operations.

           Additionally, Royal Towers has entered into a grant agreement with
HUD under the Drug Elimination Grant Program to assist in the elimination of
illegal drugs and the associated crime at the property. The grant agreement is
dated July 7, 1994. During 1995, the Partnership incurred $156,034 of costs
under the Program of which $120,867 have been capitalized in rental property.
Drug Elimination Grant revenue of $156,034 is included in other revenue in 1995
(Note 12 to the Local Limited Partnership Combined Financial Statements).

           Royal Towers Limited Partnership has a significant amount of payables
and only limited resources with which to pay such items, which raises
substantial doubt about the Royal Towers Limited Partnership's ability to
continue as a going concern. Royal Towers continued existence as a going concern
is dependent upon maintaining positive cash flows from operations or obtaining
additional fundings from partners if positive cash flows are not maintained. The
General Partner's intentions are to continue managing the property prudently so
that it can maintain positive cash flows and decrease its debts.

           Except for Trinity, all the properties in which the Partnership has
invested carry deferred acquisition notes due to the original owners of the
properties (as discussed in Note 6 to the Local Limited Partnerships' Combined
Financial Statements). In the event of a default on these notes, the note
holders would assume NHP's and the Partnership's interests in the Local Limited
Partnerships. Due to the rental market conditions where the properties are
located, the General Partner believes the amounts due on the acquisition notes
may exceed the value to be obtained by sale or refinancing opportunities. The
deferred acquisition notes mature in 2001.

           The following details the Partnership's ownership percentages of the
Local Limited Partnerships, the cost of acquisition of such ownership and the
cost of Trinity Apartments. All interests in the Local Limited Partnerships are
limited partner interests. Also included is the total mortgage encumbrance and
deferred acquisition notes and accrued interest on each property for each of the
Local Limited Partnerships and Trinity Apartments as of December 31, 1997.

Item 5.    Market for the Registrant's Partnership Interests and Related
Partnership Matters

           (a)       Interests in the Partnership were sold through a public
                     offering managed by Dean Witter Reynolds, Inc. There is no
                     established market for resale of interests in the
                     Partnership. Accordingly, an investor may be unable to sell
                     or otherwise dispose of his or her interest in the
                     Partnership.

           (b)       As of December 31, 1997, there were 1,293 registered
                     holders of 15,414 limited partnership interests (in
                     addition to 1133 Fifteenth Street Four Associates - See
                     Item 1).

           (c)       No cash dividends or distributions have been declared from
                     the inception of the Partnership to December 31, 1997.

(A)        The Partnership holds limited partnership interests in the Local
           Limited Partnerships, and since its liability for obligations is
           limited to its original investment, its investment account is not
           reduced below zero (creating a liability) for the investments in
           Local Limited Partnerships. As a result, during 1997, 1996, 1995,
           1994 and 1993, $1,716,194, $6,379,470, $1,313,743, $1,447,892 and
           $1,242,218, respectively, of losses from four, four, four, four and
           three, respectively, Local Limited Partnerships have not been
           recognized by the Partnership (see Note 3 to the Partnership's
           financial statements).

Item 7.    Management's Discussion and Analysis of Financial Condition and
Results of Operations

           The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements in certain circumstances. Certain
information included in this Report and other Partnership filings (collectively
"SEC Filings") under the Securities Act of 1933, as amended, and the Securities
Exchange Act of 1934, as amended (as well as information communicated orally or
in writing between the dates of such SEC Filings) contains or may contain
information that is forward looking, including statements regarding the effect
of government regulations. Actual results may differ materially from those
described in the forward looking statements and will be affected by a variety of
factors including national and local economic conditions, the general level of
interest rates, terms of governmental regulations that affect the Partnership
and interpretations of those regulations, the competitive environment in which
the properties


                                       8
<PAGE>   10


owned by the Local Limited Partnerships operate, the availability of working
capital and dispositions of properties owned by the Partnership.

Liquidity and Capital Resources

           The properties in which the Partnership has invested, through its
investments in the Local Limited Partnerships, receive one or more forms of
assistance from the Federal Government. As a result, the Local Limited
Partnerships' ability to transfer funds either to the Partnership or among
themselves in the form of cash distributions, loans or advances is generally
restricted by terms of these government assistance programs. These restrictions
have had an impact on the Partnership's ability to meet its cash obligations.

           Net cash provided by operations for the year ended December 31, 1997,
was $126,447 ,as compared to cash provided by operations of $217,420 in 1996 and
to cash used in operations of $20,181 in 1995. The decrease in cash provided by
operations from 1996 to 1997 resulted from a decrease in distributions received
form Local Limited Partnerships, a decrease in real estate tax refunds received,
partially offset by an increase in rental collections and an increase in
mortgage interest paid, offset by a decrease in taxes and insurance payments in
1997. The increase in cash provided by operations from 1995 to 1996 resulted
from an increase in rental collections and from a real estate tax refund
received in 1996, partially offset by an increase in other operational expenses.

           Distributions in excess of investment in Local Limited Partnerships
represent the Partnership's proportionate share of the excess cash available for
distribution from the Local Limited Partnerships. As a result of the use of the
equity method of accounting for the Partnership's investment in Local Limited
Partnerships, investment carrying values for each of the Local Limited
Partnerships has decreased to zero. Cash distributions received are recorded in
revenues as distributions received in excess of investment in Local Limited
Partnerships. Cash distributions totaling $34,016, $63,756 and $20,296 were
received from two, three and two Local Limited Partnerships, respectively,
during the years ended December 31, 1997, 1996 and 1995. The receipt of these
distributions in future years is dependent on the operations of the underlying
properties of the Local Limited Partnerships.

           Cash and cash equivalents amounted to $45,275 at December 31, 1997.
The ability of the Partnership to meet its on-going cash requirements, in excess
of cash on hand at December 31, 1997, is dependent on operations of Trinity
Apartments, distributions received from the Local Limited Partnerships, and
proceeds from the sales or refinancing of the underlying Properties. As of
December 31, 1997, the Partnership owes the General Partner $1,222,366 for
administrative and reporting services performed. In addition, at December 31,
1997, the Partnership owed NHP $626,696 for other advances. Additionally, NHP
and AIMCO have made advances totaling $7,451,013 to Trinity Apartments to cover
costs associated with the refinancing of the Partnership's mortgage note payable
for Trinity Apartments and to cover operating deficits for Trinity Apartments.
The payment of the unpaid administrative and reporting fees and advances from
the Partnership and NHP to the Local Limited Partnerships will most likely
result from the sale or refinancing of the underlying Properties of the Local
Limited Partnerships as defined by the Partnership agreement, rather than
through recurring operations. The General Partner will continue to manage the
Partnership's assets prudently in an effort to achieve positive cash flow. NHP
will evaluate lending the Partnership additional funds as such funds are needed,
but is in no way legally obligated to make such loans.

           Trinity Apartments, a rental property wholly-owned by the
Partnership, has generated substantial losses from operations which have
resulted in the accumulation of significant accounts payable and accrued
expenses at December 31, 1997 and has also necessitated significant funding from
the General Partner in prior years. The General Partner's intentions are to
continue to manage Trinity prudently so that the property can maintain positive
cash flows and pay its general obligations.

           The mortgage note payable on Trinity provided by GECC, was due June
30, 1995. On March 15, 1996, a modification agreement to the loan agreement was
signed which, among other provisions, extended the due date to March 15, 1999.
As a condition of the modification, a principal payment of $560,000 was made to
reduce the mortgage note payable to $13,140,000. In order to make the required
payment and to pay additional financing fees, the General Partner made a loan of
$667,202 to Trinity. On December 29,1997, Trinity refinanced the mortgage note
payable. GECC was paid $13,093,546 to pay off the note along with a $1,300,000
prepayment penalty representing 50% of the


                                       9
<PAGE>   11


fair market value of the project above the amount of refinanced debt as required
under the GECC mortgage agreement. Proceeds from the refinancing along with a
loan of $6,121,479 from an affiliate of the General Partner, AIMCO Properties
L.P., were used to retire the existing mortgage note, pay the prepayment penalty
of $1,300,000 and to pay accrued interest and other deferred finance costs of
$925,930. The new mortgage note payable of $9,620,000 is held by Lehman Capital
and is secured by a deed of trust on the rental property and an assignment of
all right of title and interest in, leases with the tenants. The note bears
interest at the rate of 6.557% per annum. The principal and interest are payable
by Trinity in equal monthly installments of $84,102 to December 1, 2012.

           On December 1, 1996, a fire occurred at the Royal Towers Limited
Partnership project site. Management believes that all damages will be recovered
through insurance proceeds less a $2,500 deductible. As of December 31, 1996, an
insurance receivable was recorded for $1,880,289 which includes $1,784,685 for
fire loss damages net of the deductible, and $95,604 for loss of rent for the
month of December, 1996.

           During 1997, Royal Towers Limited Partnership received approximately
$2,756,000 in insurance proceeds relating to the fire and used approximately
$2,485,000 of these proceeds as of December 31, 1997. Use of the remaining
$271,000 held in escrow by the mortgage company and the final insurance award
have not been determined or approved.

           During 1997, HUD approved withdrawals of $249,365 from the reserve
for replacements to pay outstanding fire related payables. This is considered a
loan from the reserve for replacements and must be repaid to the reserve for
replacements when reimbursement is received from the insurance company.

           In addition to amounts reimbursed from insurance proceeds, Royal
Towers Limited Partnership has incurred costs of $190,761 which are fire related
and have been included in the accompanying combined statements of operations and
$95,164 of costs which have been capitalized. Royal Towers Limited Partnership
anticipates that an additional $1,000,000 is needed to repair the property to
its pre-fire condition and is seeking insurance funds to fund such costs.

           Royal Towers Limited Partnership has a significant amount of payables
and only limited resources with which to pay such items, which raises
substantial doubt about the Royal Towers Limited Partnership's ability to
continue as a going concern. Royal Towers continued existence as a going concern
is dependent upon maintaining positive cash flows from operations or obtaining
additional fundings from partners if positive cash flows are not maintained. The
General Partner's intentions are to continue managing the property prudently so
that it can maintain positive cash flows and decrease its debts.

           During 1996, NHPMC, an affiliate of the General Partner, was
management agent under an agreement which ended on October 31,1996. At December
31, 1996, the Royal Towers Limited Partnership had accrued costs due to NHPMC
consisting of management fees, bookkeeping and accounting fees, payroll and
miscellaneous reimbursement items. In addition to the $131,027 shown as due to
management agent on the 1996 combined statements of financial position, there
was $36,735 due to NHPMC included in trade payables. During 1997, NHPMC informed
Royal Towers Limited Partnership that these amounts totaling $167,762 do not
have to be paid and therefore this amount is shown as an extraordinary gain in
the accompanying 1997 combined statements of operations.

           Except for Trinity, all the properties in which the Partnership has
invested carry deferred acquisition notes due to the original owners of the
properties. In the event of a default on these notes, the noteholders would
assume NHP's and the Partnership's interests in the Local Limited Partnerships.
Due to the rental market conditions where the properties are located, the
General Partner believes the amounts due on the acquisition notes may exceed the
value to be obtained by sale or refinancing opportunities. The deferred
acquisition notes mature in 2001.

Results of Operations

           The Partnership has invested as a limited partner in four Local
Limited Partnerships which operate four rental housing properties. In addition,
the Partnership directly owns Trinity Apartments. The Partnership's results of
operations are significantly impacted by the rental operations of Trinity
Apartments. In prior years, results of operations


                                       10
<PAGE>   12


were also affected by the Partnership's share of losses from the Local Limited
Partnerships in which it has invested to the extent the Partnership still had a
carrying basis in a respective Local Limited Partnership. As of December 31,
1997 and 1996, the Partnership had no carrying value in any of the Local Limited
Partnerships and therefore, reflected no share of losses from the four Local
Limited Partnerships.

           The Partnership's net loss increased to $1,997,619 in 1997 from a net
loss of $520,270 in 1996. The net loss per unit of limited partnership interest
increased to $127 in 1997 from net loss per unit of $33 in 1996 for the 15,414
units outstanding throughout both years. The primary reasons for this increase
in net loss include a $1,300,000 prepayment penalty resulting from the Trinity
mortgage refinancing in 1997 and approximately $100,000 increase in interest on
partner loans.

           The Partnership did not recognize $1,716,194 of its allocated share
of losses from the four Local Limited Partnerships in 1997, as the Partnership's
net book investment in them was reduced to zero (see Note 3 to the Partnership's
financial statements). The Partnership's share of losses from the Local Limited
Partnerships, if not limited to its investment account balance, would have
decreased $4,663,276 between years. The decrease was primarily due to impairment
losses on rental property of $2,700,000 and $1,960,000 for Loring Towers and
Royal Towers, respectively, taken in 1996. There were no such impairment losses
recorded in 1997. Additionally, there was a decrease in rental income and an
increase in operating expenses of the rental properties, which were offset by an
extraordinary gain on forgiveness of debt recorded in 1997.

           The Partnership's net loss decreased to $520,270 in 1996 from a net
loss of $889,927 in 1995. The net loss per unit of limited partnership interest
decreased to $33 in 1996 from net loss per unit of $58 in 1995 for the 15,414
units outstanding throughout both years. The primary reasons for this decrease
in net loss include an increase in rental income of approximately $147,000, an
increase in distributions in excess of investment in Local Limited Partnerships
of approximately $43,000 and decreases in real estate taxes and mortgage
interest of approximately $214,000 and $76,000, respectively. The decrease in
real estate taxes was the result of a reassessment of Trinity apartments which
resulted in tax refund of approximately $124,000.

           The Partnership did not recognize $6,379,470 of its allocated share
of losses from the four Local Limited Partnerships in 1996, as the Partnership's
net book investment in them was reduced to zero (see Note 3 to the Partnership's
financial statements). The Partnership's share of losses from the Local Limited
Partnerships, if not limited to its investment account balance, would have
increased $5,065,727 between years. The increase was primarily due to impairment
losses on rental property of $2,700,000 and $1,960,000 for Loring Towers and
Royal Towers, respectively, taken in 1996, and from a decrease in rental income
and an increase in operating expenses of the rental properties.

                   NATIONAL HOUSING PARTNERSHIP REALTY FUND IV

                              A LIMITED PARTNERSHIP

                          NOTES TO FINANCIAL STATEMENTS

1.         SUMMARY OF PARTNERSHIP ORGANIZATION AND SIGNIFICANT ACCOUNTING
           POLICIES

           Organization

           National Housing Partnership Realty Fund IV (the Partnership) is a
limited partnership organized under the Maryland Revised Uniform Limited
Partnership Act on January 8, 1986. The Partnership was formed for the purpose
of raising capital by offering and selling limited partnership interests, and
then using that capital to acquire and operate (either directly or through
investment as a limited partner in Local Limited Partnerships) multi-family
rental apartments, some of which are financed and/or operated with one or more
forms of rental or financial assistance from the U.S. Department of Housing and
Urban Development (HUD). On February 21, 1986, inception of operations, the
Partnership began raising capital and acquiring interests in Local Limited
Partnerships.

           The General Partner was authorized to raise capital for the
Partnership by offering and selling to additional limited partners not more than
35,000 interests at a price of $1,000 per interest. During 1986, 15,414
interests were sold to additional limited partners. The offering was terminated
on October 14, 1986.

           On June 3, 1997, Apartment Investment and Management Company, a
Maryland corporation ("AIMCO" and, together with its subsidiaries and other
controlled entities, the "AIMCO Group"), acquired all of the issued and
outstanding capital stock of NHP Partners, Inc., a Delaware corporation ("NHP
Partners"), and the AIMCO Group acquired all of the outstanding interests in NHP
Partners Two Limited Partnership, a Delaware limited partnership ("NHP Partners
Two"). The acquisitions were made pursuant to a Real Estate Acquisition
Agreement, dated as of May 22, 1997 (the "Agreement"), by and among AIMCO, AIMCO
Properties, L.P., a Delaware limited partnership (the "Operating Partnership"),
Demeter Holdings Corporation, a Massachusetts corporation ("Demeter"), Phemus
Corporation, a Massachusetts corporation ("Phemus"), Capricorn Investors, L.P.,
a Delaware limited partnership ("Capricorn"), J. Roderick Heller, III and NHP
Partners Two LLC, a Delaware limited liability company ("NHP Partners Two LLC").
NHP Partners owns all of the outstanding capital stock of the National
Corporation for Housing Partnerships, a District of Columbia corporation
("NCHP"), which is the general partner of The National Housing Partnership, a
District of Columbia limited partnership ("NHP"). Together, NCHP and NHP
Partners Two own all of the outstanding partnership interests in NHP. NHP is the
general partner of National Housing Partnership Realty Fund IV (a Maryland
Limited Partnership) (the "Registrant" or "Partnership"). As a result of these
transactions, the AIMCO Group has acquired control of the general partner of the
Registrant and, therefore, may be deemed to have acquired control of the
Registrant.

           The Original Limited Partner of the Partnership is 1133 Fifteenth
Street Four Associates, whose limited partners were key employees of NCHP at the
time the Partnership was formed and whose general partner is NHP.

           During 1986, the Partnership acquired 99% limited partnership
interests in four limited partnerships (Local Limited Partnerships) which were
organized in 1986 to operate existing rental housing projects. In addition,
during 1986, the Partnership directly purchased Trinity Apartments (Trinity), a
conventionally financed rental apartment project.

           Significant Accounting Policies

           The financial statements of the Partnership are prepared on the
accrual basis of accounting. Public offering costs were recorded as a direct
reduction to the capital accounts of the limited partners. Direct costs of
acquisition, including acquisition fees and reimbursable acquisition expenses
paid to the General Partner, have been capitalized as investments in Trinity or
the Local Limited Partnerships. Other fees and expenditures of the Partnership
are recognized

                   NATIONAL HOUSING PARTNERSHIP REALTY FUND IV

                              A LIMITED PARTNERSHIP

                          NOTES TO FINANCIAL STATEMENTS

                                  (CONTINUED)


as expenses in the period the related services are performed. Deferred finance
costs are amortized over the appropriate loan period on a straight-line basis.

           The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

           Depreciation of the buildings and improvements is computed using the
straight-line method, assuming a 50 year life from the date of initial occupancy
and depreciation of equipment is calculated using accelerated methods over
estimated useful lives of 5 to 27 years.

           The Partnership recognizes rental revenue in the month earned in
accordance with signed resident tenant lease agreements.

           The financial statements include the accounts of the Partnership and
its wholly-owned subsidiary, Trinity. All significant intercompany transactions
have been eliminated.

           Investments in Local Limited Partnerships are accounted for using the
equity method and thus are carried at cost less the Partnership's share of the
Local Limited Partnerships' losses and distributions (see Note 3). An investment
account is maintained for each of the limited partnership investments and losses
are not taken once an investment account has decreased to zero. Cash
distributions are limited by the Regulatory Agreements between the Local Limited
Partnerships and HUD to the extent of surplus cash as defined by HUD.
Undistributed amounts are cumulative and may be distributed in subsequent years
if future operations provide surplus in excess of current requirements.
Distributions received from Local Limited Partnerships in which the
Partnership's investment account has decreased to zero are recorded as revenue
in the year received.

           For purposes of the Statements of Cash Flows, the Partnership
considers all highly liquid debt instruments purchased with initial maturities
of three months or less to be cash equivalents.

3.         INVESTMENTS IN AND ADVANCES TO LOCAL LIMITED PARTNERSHIPS

           The Partnership owns a 99% limited partnership interest in Loring
Towers Apartments Limited Partnership, Kennedy Homes Limited Partnership,
Capital Park Limited Partnership, and Royal Towers Limited Partnership. These
investments are accounted for using the equity method because, as a limited
partner, the liability of the Partnership is limited to its investment in the
Local Limited Partnerships. As a limited partner, the Partnership does not
exercise control over the activities of the Local Limited Partnerships in
accordance with the partnership agreements. Thus, the investments are carried at
cost less the Partnership's share of the Local Limited Partnerships' losses and
distributions. However, since the Partnership is neither legally liable for the
obligations of the Local Limited Partnerships, nor otherwise committed to
provide additional support to them, it does not recognize losses once its
investment in each of the individual Local Limited Partnerships, reduced for its
share of losses and cash distributions, reaches zero. As a result, during 1997,
1996 and 1995, the Partnership did not recognize $1,716,194, $6,379,470 and
$1,313,743, respectively of its allocated share of losses from four Local
Limited Partnerships. As of December 31, 1997 and 1996, the Partnership had not
recognized $14,346,578 and $12,630,384, respectively, of its cumulative
allocated share of losses from four of the Local Limited Partnerships.

           During 1996, one Local Limited Partnership repaid $200 and $107
principal and accrued interest to the Partnership. No working capital advances
or recoveries occurred between the Partnership and the Local Limited
Partnerships during 1997 or 1995. As of December 31, 1997 and 1996, $12,200 was
owed by one Local Limited Partnerships to the Partnership. During 1993, the
Partnership re-evaluated the timing of the collectibility of these advances and
determined, based on the Local Limited Partnerships' operations, that such
advances were not likely to be collected; therefore, the Partnership treated the
advance balance as additional investments. Due to the cumulative losses incurred
but not recognized on the investments, the balance was then reduced to zero,
with the corresponding charge to operations, shown as "Share of Losses in Local
Limited Partnerships" in the Statement of Operations. To the extent these
advances are repaid by the Local Limited Partnerships in the future, operations
will be credited upon repayment.

           Summaries of the combined financial position of the aforementioned
Local Limited Partnerships as of December 31, 1997 and 1996 and the combined
results of operations for the years ended December 31, 1997, 1996, and 1995 are
as follows:

           The combined financial statements of the Local Limited Partnerships
are prepared on the accrual basis of accounting. Each Local Limited Partnership
was formed during 1986 for the purpose of acquiring and operating a rental
housing project originally organized under Section 236 or Section 221(d)(3) of
The National Housing Act. All four projects receive rental assistance from HUD.

           Of the contracts above expiring during 1998, contracts for 496 units
expire on or prior to September 30, 1998. Congress has passed legislation which
will provide a one-year renewal contract to replace those contracts. The
contract covering the remaining 123 units expires in October, 1998. It is
uncertain whether the agreement will be renewed, as well as the remaining
contracts expiring after 1998, and if so, on what terms.

                   NATIONAL HOUSING PARTNERSHIP REALTY FUND IV

                              A LIMITED PARTNERSHIP

                          NOTES TO FINANCIAL STATEMENTS

                                  (CONTINUED)


           For the past several years, various proposals have been advanced by
the United States Department of Housing and Urban Development ("HUD"), Congress
and others proposing the restructuring of HUD's rental assistance programs under
Section 8 of the United States Housing Act of 1937 ("Section 8"), under which
896 units, 97 percent of the total units owned by the properties in which the
Partnership has invested (excluding Trinity Apartments), receive rental
subsidies. On October 27, 1997, the President signed into law the Multifamily
Assisted Housing Reform and Affordability Act of 1997 (the "1997 Housing Act").
Under the 1997 Housing Act, certain properties assisted under Section 8, with
rents above market levels and financed with HUD-insured mortgage loans, will be
restructured by adjusting subsidized rents to market levels, thereby potentially
reducing rent subsidies, and lowering required debt service costs as needed to
ensure financial viability at the reduced rents and rent subsidies. The 1997
Housing Act retains project-based subsidies for most properties (properties in
rental markets with limited supply, properties serving the elderly, and certain
other properties). The 1997 Housing Act phases out project-based subsidies on
selected properties servicing families not located in rental markets with
limited supply, converting such subsidies to a tenant-based subsidy. Under a
tenant-based system, rent vouchers would be issued to qualified tenants who then
could elect to reside at properties of their choice, provided such tenants have
the financial ability to pay the difference between the selected properties'
monthly rent and the value of the vouchers, which would be established based on
HUD's regulated fair market rent for the relevant geographical areas. The 1997
Housing Act provides that properties will begin the restructuring process in
federal fiscal year 1999 (beginning October 1, 1998), and that HUD will issue
final regulations implementing 1997 Housing Act on or before October 27, 1998.
With respect to Housing Assistance Payments Contracts ("HAP Contracts") expiring
before October 1, 1998, Congress has elected to renew them for one-year terms,
generally at existing rents, so long as the properties remain in compliance with
the HAP Contracts. While the Partnership does not expect the provisions of the
1997 Housing Act to result in a significant number of tenants relocating from
properties owned by the Local Limited Partnerships, there can be no assurance
that the provisions will not significantly affect the operations of the
properties of the Local Limited Partnerships. Furthermore, there can be no
assurance that other changes in Federal housing subsidy policy will not occur.
Any such changes could have an adverse effect on the operation of the
Partnership.

           Depreciation of the buildings and improvements is computed using the
straight-line method, assuming a 50-year life from the date of initial occupancy
and depreciation of equipment is calculated using accelerated methods over
estimated useful lives ranging from 5 to 27 years.

           The mortgage notes payable are insured by the Federal Housing
Administration (FHA) and secured by first deeds of trust on the rental
properties. The notes bear interest at rates ranging from 6% to 8.5% per annum.
For the three rental housing projects insured under Section 236, FHA makes
subsidy payments directly to the mortgage lenders reducing the monthly principal
and interest payments of the project owner to an effective interest rate of 1%
over the 40-year term of the notes. The liability of the Local Limited
Partnerships under the mortgage notes is limited to the underlying value of the
real estate collateral plus other amounts deposited with the lenders.

           Deferred acquisition notes of $7,174,900 bear interest at the rate of
9% per annum, compounded semi-annually. These notes are nonrecourse and are
secured by security interests in all partnership interests of the Local Limited
Partnerships. Neither principal nor interest is payable currently; all principal
and accrued interest are payable upon the earlier of the sale, transfer, or
refinancing of the projects or 2001. The notes may be prepaid in whole or in
part at any time without penalty.

           In March 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 121 "Accounting For The
Impairment Of Long-Lived Assets And For Long-Lived Assets To Be

                              A LIMITED PARTNERSHIP

                          NOTES TO FINANCIAL STATEMENTS

Disposed Of" (the "Statement") effective for financial statements for fiscal
years beginning after December 15, 1995. This Statement requires an impairment
loss to be recognized if the sum of estimated future cash flows (undiscounted
and without interest charges) is less than the carrying amount of rental
property. The impairment loss would be the amount by which the carrying value
exceeds the fair value of the rental property. If the rental property is to be
disposed of, fair value is calculated net of costs to sell.

           During 1996, two Local Limited Partnerships recognized impairment
losses on their rental properties in the amount of $2,700,000 and $1,960,000.
Because the Local Limited Partnerships' deferred acquisition notes were due
March 27, 2001, the Local Limited Partnerships' estimated net cash flow was only
for the period January 1, 1997 to March 27, 2001. As a result of this limited
holding period, the estimated net cash flow was less than the carrying amount at
December 31, 1996. The Local Limited Partnership used the Direct Capitalization
Method to estimate the fair value of the rental property. Using this Method,
estimated annual cash flow generated by the property is divided by an overall
capitalization rate to estimate the rental property's fair value. The impairment
losses had no impact on the Partnership's operations, since the Partnership's
investments in the Local Limited Partnerships had been reduced to zero in a
prior year.

           Additionally, regardless of whether the impairment loss of an
individual property has been recorded or not, the carrying value of each of the
rental properties may still exceed their fair market value as of December 31,
1997. Should a Local Limited Partnership be forced to dispose of any if its
properties, it could incur a loss.

           During 1996, NHPMC, an affiliate of the General Partner, was
management agent for each of the properties, except that for Royal Towers the
agreement ended on October 31,1996. At December 31, 1996, the Royal Towers
Limited Partnership had accrued costs due to NHPMC consisting of management
fees, bookkeeping and accounting fees, payroll and miscellaneous reimbursement
items totaling $167,762. During 1997, NHPMC informed Royal Towers Limited
Partnership that these amounts totaling $167,762 do not have to be paid and
therefore this amount is shown as an extraordinary gain in the accompanying 1997
combined statements of operations.

           On December 1, 1996, a fire occurred at the Royal Towers Limited
Partnership project site. Management believes that all damages will be recovered
through insurance proceeds less a $2,500 deductible. As of December 31, 1996, an
insurance receivable was recorded for $1,880,289 which includes $1,784,685 for
fire loss damages net of the deductible, and $95,604 for loss of rent for the
month of December, 1996.

           During 1997, Royal Towers Limited Partnership received approximately
$2,756,000 in insurance proceeds relating to the fire and used approximately
$2,485,000 of these proceeds as of December 31, 1997. Use of the remaining
$271,000 held in escrow by the mortgage company and the final insurance award
have not been determined or approved. During 1997, HUD approved withdrawals of
$249,365 from the reserve for replacements to pay outstanding fire related
payables. This is considered a loan from the reserve for replacements and must
be repaid to the reserve for replacements when reimbursement is received from
the insurance company.

           In addition to amounts reimbursed from insurance proceeds, Royal
Towers Limited Partnership has incurred costs of $190,761 which are fire related
and have been included in the accompanying combined statements of operations and
$95,164 of costs which have been capitalized. Royal Towers Limited Partnership
anticipates that an additional $1,000,000 is needed to repair the property to
its pre-fire condition and is seeking insurance funds to fund such costs.

           Royal Towers Limited Partnership has a significant amount of payables
and only limited resources with which to pay such items, which raises
substantial doubt about the Local Limited Partnership's ability to continue as a
going concern. Royal Towers Limited partnership continued existence as a going
concern is dependent upon maintaining positive cash flows from operations or
obtaining additional fundings from partners if positive cash flows are not
maintained. The General Partner's intentions are to continue managing the
property prudently so that it can maintain positive cash flows and decrease its
debts.

5.         MORTGAGE NOTE PAYABLE

           Since July 2, 1990, Trinity had operated under a mortgage loan
provided by General Electric Capital Corporation ("GECC") in the amount of
$13,700,000. The mortgage note payable was secured by an assignment of leases,
and by a deed of trust on the rental property. The loan had a term of five years
during which no principal payments were required. A modification agreement was
executed on March 15, 1996, extending the maturity date of the loan to March 15,
1999. As a condition of the modification, the Partnership paid principal of
$560,000 during 1996. This reduced the mortgage note payable to $13,140,000,
which was the outstanding balance at December 31, 1996.

           Interest only, at the Contract Index Rate, on the mortgage was
payable monthly beginning April 1, 1996 through March 1, 1999. In addition,
beginning April 1, 1996 and continuing each July, October, December and April,
installments of principal in the amount equal to 100% of the net cash flow (as
defined) were due and payable. During 1997, Trinity made principal payments of
$46,454 from net cash flow as required. On March 15, 1999, the entire unpaid
principal and interest was due and payable. The Contract Index Rate is equal to
3.25% per annum in excess of the GECC Composite Commercial Paper Rate.

           On December 29,1997, Trinity refinanced the mortgage. GECC was paid
$13,093,546 to pay off the note along with $1,300,000 prepayment penalty
representing 50% of the fair market value of the project above the amount of
refinanced debt as required under the GECC mortgage agreement. Proceeds from the
refinancing along with a loan of $6,121,479 from an affiliate of the General
Partner, AIMCO Properties L.P., were used to retire the existing

interest and other deferred finance costs of $925,930.

           The new mortgage note payable of $9,620,000 is held by Lehman Capital
and is secured by a deed of trust on the rental property and an assignment of
all right of title and interest in, leases with the tenants. The note bears
interest at the rate of 6.557% per annum. The principal and interest are payable
by Trinity in equal monthly installments of $84,102 to December 1, 2012.

Principal payments are due as follows:

           Under the agreement with the new mortgage lender, Trinity was
required to establish a repair escrow of $303,000 and is required to make
monthly escrow deposits with the lender for taxes, hazard and liability
insurance.

           The liability of the Partnership under the mortgage note is limited
to the underlying value of the real estate collateral plus other amounts
deposited with the lender.

6.         TRANSACTIONS WITH THE GENERAL PARTNER AND AFFILIATES OF THE GENERAL
           PARTNER

           The Partnership accrued administrative and reporting fees payable to
the General Partner of $115,604 in 1997, 1996 and 1995. No payments for these
fees were made during 1997, 1996 or 1995. The balance owed to the General
Partner at December 31, 1997 and 1996 was $1,222,366 and $1,106,762,
respectively.

           During 1997, 1996 and 1995, the General Partner made working capital
advances of $21,212, $669,881 and $38,907, respectively, to the Partnership and
to Trinity Apartments. In addition, AIMCO advanced $6,121,479 for the
refinancing of Trinity's mortgage. During 1996, the Partnership repaid advances
of $5,764 to the General Partner. No repayments of working capital advances were
made in 1997 or 1995. The balance owed to the General Partner and AIMCO at
December 31, 1997 and 1996 was $8,055,209. and $1,912,518, respectively.
Interest is charged at the Chase Manhattan Bank rate of prime plus 2%. Chase
Manhattan Bank prime was 8.5% at December 31, 1997. During 1997, 1996 and 1995,
interest of $376,687, $278,198 and $250,478, respectively was accrued and
expensed. During 1996, interest of $438 was repaid to the General Partner. The
interest balance owed to the General Partner at December 31,

1997 and 1996 was $1,838,021 and $1,461,334, respectively. Additionally, annual
partnership administrative fees of $7,500 were accrued by Trinity Apartments
during 1997, 1996 and 1995, respectively. These fees are payable to the General
Partner without interest from cash available for distribution to partners. No
payments for these fees were made during 1997, 1996 or 1995. As of December 31,
1997 and 1996, $22,500 and $15,000, respectively, was owed to the General
Partner for these fees.

           NHP Management Company ("NHPMC"), formerly a wholly owned subsidiary
of NHP Incorporated ("NHPI"), is the project management agent for the projects
operated by the Local Limited Partnerships, except for Royal Towers Limited
Partnership which changed management agent on November 1, 1996. In 1996, NHPI,
which at that time owned 100% of NHPMC, paid an affiliate of NHP $400,321 to
secure the rights to manage Trinity for the three years ending March 31, 1999.
During May 1997, AIMCO acquired approximately 51% of the voting stock of NHPI.
An additional 3% of the voting stock was acquired by AIMCO in August 1997. On
December 8, 1997, the NHPI stockholders elected to merge with AIMCO. After the
merger, NHPMC became a wholly owned subsidiary of AIMCO. NHPMC and other
affiliates of NCHP earned $494,836, $517,575 and $501,645 from the Local Limited
Partnerships and $197,577, $218,751 and $205,756 from Trinity for management
fees and other services provided to the Local Limited Partnerships during 1997,
1996 and 1995, respectively. At December 31, 1997 and 1996, amounts due NHPMC
and unpaid by the Local Limited Partnerships amounted to $4,920 and $163,637,
respectively.

           Personnel working at the project sites, which are managed by NHPMC,
were employees of NHPI during the period January 1, 1996 through December 8,
1997 and became employees of NHPMC (as a successor employer) as of December 8,
1997 and, therefore, the projects reimbursed NHPI and NHPMC for the actual
salaries and related benefits. Prior to January 1, 1996, project employees were
employees of NCHP. Total reimbursements earned for salaries and benefits for the
years ended December 31, 1997, 1996 and 1995, were approximately $462,000,
$714,000 and $642,000, respectively, from the Local Limited Partnerships and
approximately $293,000, $291,000 and $230,000, respectively, from Trinity. At
December 31, 1997 and 1996 account payable included $501 and $16,413 due to
NHPMC and NCHP, respectively.

7.         INCOME TAXES

           The Partnership is not taxed on its income. The partners are taxed in
their individual capacities upon their distributive share of the Partnership's
taxable income and are allowed the benefits to be derived from off-setting their
distributive share of the tax losses against taxable income from other sources
subject to application of passive loss rules. The taxable income or loss differs
from amounts included in the statement of operations because of different
methods used in computing depreciation and determining the losses of the Local
Limited Partnerships. The tax loss is allocated to the partner groups in
accordance with Section 704(b) of the Internal Revenue Code and therefore is not
necessarily proportionate to the interest percentage owned.

           For Federal income tax purposes, both the Partnership and the four
Local Limited Partnerships compute depreciation of the buildings and
improvements using the Accelerated Cost Recovery System (ACRS) and the Modified
Accelerated Cost Recovery System (MACRS), while for financial statement
purposes, depreciation is computed using the straight-line method, assuming a
50-year life from the date of initial occupancy. Rent received in advance is
included as income in determining the taxable income or loss for Federal income
tax purposes, while for

result from the allocation of tax losses in accordance with Section 704(b) of
the Internal Revenue Code.

           As discussed in Note 3, one of the Local Limited Partnerships in
which the Partnership has invested may not be able to continue as a going
concern. Should a Local Limited Partnership not continue as a going concern or
the Partnership itself not continue as a going concern (see Note 8), there could
be adverse tax consequences to the partners in the Partnership. The impact of
the tax consequences is dependent upon each partner's individual tax situation.

8.         FUTURE OPERATIONS

           Trinity Apartments, a rental property wholly-owned by the
Partnership, has generated substantial losses from operations in prior years
which has necessitated significant funding from the General Partner as described
in Note 6.

            The Partnership's intentions are to manage Trinity Apartments
prudently so that the property can maintain positive cash flows in order to pay
its expenses and to repay its loans as operations permit. NHP will evaluate
loaning Trinity Apartments additional funds as such funds are needed, but it is
not legally obligated to make such loans.

9.         ALLOCATION OF RESULTS OF OPERATIONS, CASH DISTRIBUTIONS AND GAINS AND
           LOSSES FROM SALE OR REFINANCING

           Cash received from sales or refinancing of any underlying property of
the Local Limited Partnerships, after payment of the applicable mortgage debt
and the payment of all expenses related to the transaction, is to be distributed
in the following manner:

           Second, to the establishment of any reserves which the General

           Finally, 85% of the remaining sales proceeds to the Limited Partners
           and 15% to the General Partner.

           Net income or loss from operations is allocated 98% to the Limited
Partners, 1% to the General Partner and 1% to the Original Limited Partner. Cash
distributions from operations, after payment of certain obligations including
reimbursement on a cumulative basis of direct expenses incurred by the General
Partner or its affiliate in managing the properties and payment of annual
cumulative administrative and reporting fees, is distributed 98% to the Limited
Partners, 1% to the General Partner and 1% to the Original Limited Partner.

           Gain for federal income tax purposes realized in the event of
dissolution of the Partnership or upon sale of interests in a Local Limited
Partnership or underlying property will be allocated in the following manner:

           such Limited Partner's capital contribution bears to the aggregate of
           all Limited Partners' capital contributions;

           Fourth, to the Limited Partners, until each Limited Partner has been
           allocated in such an amount equal to a cumulative noncompounded 9%
           annual return on their capital contribution, after deduction of (a)

           the General Partner.

           Losses for federal income tax purposes realized in the event of
dissolution of the Partnership or upon sale of interests in a Local Limited
Partnership or underlying property will be allocated 85% to the Limited Partners
and 15% to the General Partner.

10.        FAIR VALUE OF FINANCIAL INSTRUMENTS

           FASB Statement No. 107, "Disclosures About Fair Value of Financial
Instruments," requires disclosure of fair value information about significant
financial instruments, when it is practicable to estimate that value and
excessive costs would not be incurred. To estimate the fair value of the
balances due to the General Partner and accrued interest thereon, excessive
costs would be incurred and, therefore, no estimate has been made. The
Partnership believes that the carrying value of other assets and liabilities
reported on the statement of financial position that require such disclosure
approximates fair value.

11.        NONCASH INVESTING ACTIVITY

           During 1997 and 1996, the Partnership incurred costs of $1,947 and
$4,284, respectively, for additions to building and equipment which are included
in accounts payable as of December 31, 1997 and 1996, respectively.

Item 11.  Executive Compensation

          National Housing Partnership Realty Fund IV has no officers or

reimbursements are paid to the General Partner and its affiliates. Following is
a summary of such fees paid or accrued during the year ended December 31, 1997:

          (i)     Administrative and reporting fees of $115,604 accrued during
                  the year but not yet paid to the General Partner for managing
                  the affairs of the Partnership and for investor services.  No
                  payments were made in 1997.

          (ii)    Annual partnership administration fee of $30,000 to the
                  General Partner for its services as General Partner of the
                  four Local Limited Partnerships. Payments of $15,011 were
                  made in 1997. Trinity Apartments also accrued $7,500 in such
                  fees during 1997.

          (iii)   An affiliate of the General Partner, NHP Management Company
                  (NHPMC) is the project management agent for three of the
                  projects operated by the Local Limited Partnerships, as well
                  as Trinity Apartments. During 1997, NHPMC and other
                  affiliates of NCHP earned $494,836 and $197,577 for management
                  fees and other services provided to the Local Limited
                  Partnerships and Trinity Apartments, respectively. In 1996,
                  NHPI, which at that time owned 100% of NHPMC, paid on
                  affiliate of NHP $400,321 to secure the rights to manage
                  Trinity for the three years ending March 31, 1999.

          (iv)    In 1997, personnel working at the project sites which were
                  managed by NHPMC were NHP Incorporated employees and
                  subsequent to December 8, 1997 NHPMC employees, and therefore
                  the project reimbursed NHPI and NHPMC for the actual salaries
                  and related benefits. Total reimbursements for salaries and
                  benefits earned for the year ended December 31, 1997, were
                  approximately $462,000 for the Local Limited Partnerships and
                  $293,000 for Trinity Apartments.

Independent Auditors' Report

To The Partners of
    National Housing Partnership Realty Fund IV
Indianapolis, IN

We have audited the accompanying combined statements of financial position of
the Local Limited Partnerships in which National Housing Partnership Realty Fund
IV (the Partnership) holds a limited partnership interest as of December 31,
1997 and 1996, and the related combined statements of operations, partners'
deficit, and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the combined financial position of the Local Limited Partnerships in
which National Housing Partnership Realty Fund IV holds a limited partnership
interest as of December 31, 1997 and 1996 and the combined results of their
operations and cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

                   NATIONAL HOUSING PARTNERSHIP REALTY FUND IV

                           LOCAL LIMITED PARTNERSHIPS

                     NOTES TO COMBINED FINANCIAL STATEMENTS


1.         SUMMARY OF PARTNERSHIP ORGANIZATION, BASIS OF COMBINATION AND
           SIGNIFICANT ACCOUNTING POLICIES

           Organization

           National Housing Partnership Realty Fund IV (the Partnership) is a
limited partnership organized under the Maryland Revised Uniform Limited
Partnership Act on January 8, 1986. The Partnership was formed for the purpose
of raising capital by offering and selling limited partnership interests, and
then using that capital to acquire and operate (either directly or through
investment as a limited partner in Local Limited Partnerships) existing
multi-family rental apartments, some of which are financed and/or operated with
one or more forms of rental or financial assistance from the U.S. Department of
Housing and Urban Development (HUD). On February 21, 1986, inception of
operations, the Partnership began raising capital and acquiring interests in
Local Limited Partnerships.

           During 1986, the Partnership acquired 99% Limited Partnership
interests in four limited partnerships (the Local Limited Partnerships) which
were organized in 1986 to acquire and operate existing rental housing projects.
The rental housing projects were originally organized under Sections 236 or
221(d)(3) of the National Housing Act. As a limited partner, the Partnership
does not exercise control over the activities of the Local Limited Partnerships
in accordance with the partnership agreements.

           On June 3, 1997, Apartment Investment and Management Company, a
Maryland corporation ("AIMCO" and, together with its subsidiaries and other
controlled entities, the "AIMCO Group"), acquired all of the issued and
outstanding capital stock of NHP Partners, Inc., a Delaware corporation ("NHP
Partners"), and the AIMCO Group acquired all of the outstanding interests in NHP
Partners Two Limited Partnership, a Delaware limited partnership ("NHP Partners
Two"). The acquisitions were made pursuant to a Real Estate Acquisition
Agreement, dated as of May 22, 1997 (the "Agreement"), by and among AIMCO, AIMCO
Properties, L.P., a Delaware limited partnership (the "Operating Partnership"),
Demeter Holdings Corporation, a Massachusetts corporation ("Demeter"), Phemus
Corporation, a Massachusetts corporation ("Phemus"), Capricorn Investors, L.P.,
a Delaware limited partnership ("Capricorn"), J. Roderick Heller, III and NHP
Partners Two LLC, a Delaware limited liability company ("NHP Partners Two LLC").
NHP Partners owns all of the outstanding capital stock of the National
Corporation for Housing Partnerships, a District of Columbia corporation
("NCHP"), which is the general partner of The National Housing Partnership, a
District of Columbia limited partnership ("NHP"). Together, NCHP and NHP
Partners Two own all of the outstanding partnership interests in NHP. NHP is the
general partner of National Housing Partnership Realty Fund IV (a Maryland
Limited Partnership) (the "Registrant" or "Partnership"). As a result of these
transactions, the AIMCO Group has acquired control of the general partner of the
Registrant and, therefore, may be deemed to have acquired control of the
Registrant.

           Basis of Combination

           The combined financial statements include the accounts of the
following four Local Limited Partnerships in which the Partnership holds a
limited partnership interest:

           Capital Park Limited Partnership
           Kennedy Homes Limited Partnership
           Loring Towers Apartments Limited Partnership
           Royal Towers Limited Partnership

                     NOTES TO COMBINED FINANCIAL STATEMENTS

                                   (CONTINUED)


           Significant Accounting Policies

           The financial statements of the Local Limited Partnerships are
prepared on the accrual basis of accounting. Depreciation of the buildings and
improvements is computed using the straight-line method, assuming a 50-year life
from the date of initial occupancy. Cash distributions are limited by the
Regulatory Agreements between the Local Limited Partnerships and HUD to the
extent of surplus cash as defined by HUD. Undistributed amounts are cumulative
and may be distributed in subsequent years if future operations provide surplus
cash in excess of current requirements.

           The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

           For purposes of the statements of cash flows, the Partnership
considers all highly liquid debt instruments purchased with initial maturities
of three months or less to be cash equivalents.

2.         ACCOUNTS RECEIVABLE

           Accounts receivable consist of the following:

3.         HOUSING ASSISTANCE AGREEMENTS

           The Federal Housing Administration (FHA) has contracted with the four
subsidized rental projects under Section 8 of Title II of the Housing and
Community Development Act of 1974 to make housing assistance payments to the
Local Limited Partnerships on behalf of qualified tenants. The terms of the
agreements are five years with one or two five-year renewal options. The
agreements expire at various dates ranging from 1997 to 2008 as follows:

</TABLE>

           Of the contracts above expiring during 1998, contracts for 496 units
expire on or prior to September 30, 1998. Congress has passed legislation which
will provide a one-year renewal contract to replace those contracts. The
contract covering the remaining 123 units expires in October, 1998. It is
uncertain whether the agreement will be renewed, as well as the remaining
contracts expiring after 1998, and if so, on what terms.

           For the past several years, various proposals have been advanced by
the United States Department of Housing and Urban Development ("HUD"), Congress
and others proposing the restructuring of HUD's rental assistance programs under
Section 8 of the United States Housing Act of 1937 ("Section 8"), under which
896 units, 97 percent of the total units owned by the properties in which the
Partnership has invested, receive rental subsidies. On October 27, 1997, the
President signed into law the Multifamily Assisted Housing Reform and
Affordability Act of 1997 (the "1997 Housing Act"). Under the 1997 Housing Act,
certain properties assisted under Section 8, with rents above market levels and
financed with HUD-insured mortgage loans, will be restructured by adjusting
subsidized rents to market levels, thereby potentially reducing rent subsidies,
and lowering required debt service costs as needed to ensure financial viability
at the reduced rents and rent subsidies. The 1997 Housing Act retains
project-based subsidies for most properties (properties in rental markets with
limited supply, properties serving the elderly, and certain other properties).
The 1997 Housing Act phases out project-based subsidies on selected properties
servicing families not located in rental markets with limited supply, converting
such subsidies to a tenant-based subsidy. Under a tenant-based system, rent
vouchers would be issued to qualified tenants who then could elect to reside at
properties of their choice, provided such tenants have the financial ability to
pay the difference between the selected properties' monthly rent and the value
of the vouchers, which would be established based on HUD's regulated fair market
rent for the relevant geographical areas. The 1997 Housing Act provides that
properties will begin the restructuring process in federal fiscal year 1999
(beginning October 1, 1998), and that HUD will issue final regulations
implementing 1997 Housing Act on or before October 27, 1998. With respect to
Housing Assistance Payments Contracts ("HAP Contracts") expiring before October
1, 1998, Congress has elected to renew them for one-year terms, generally at
existing rents, so long as the properties remain in compliance with the HAP
Contracts. While the Partnership does not expect the provisions of the 1997
Housing Act to result in a significant number of tenants relocating from
properties owned by the Local Limited Partnerships, there can be no assurance
that the provisions will not significantly affect the operations of the
properties of the Local Limited Partnerships. Furthermore, there can be no
assurance that other changes in Federal housing subsidy policy will not occur.
Any such changes could have an adverse effect on the operation of the
Partnership.

           The Local Limited Partnerships received a total of $3,217,164,
$3,337,702 and $3,407,079 during 1997, 1996 and 1995, respectively, in the form
of housing assistance payments which is included in "Rental Income" in the
combined statements of operations.

5.         MORTGAGE NOTES PAYABLE

           The mortgage notes payable are insured by FHA and secured by first
deeds of trust on the rental properties. The notes bear interest at rates
ranging from 6% to 8.5% per annum. FHA, under an interest reduction contract
with the three Section 236 properties, makes subsidy payments directly to the
mortgage lender reducing the monthly principal and interest payments of the
project owner to an effective interest rate of 1% over the 40-year terms of the
notes. The liability of the Local Limited Partnerships under the mortgage notes
is limited to the underlying value of the real estate collateral, plus other
amounts deposited with the lenders.

           Under agreements with the mortgage lenders and FHA, the Local Limited
Partnerships are required to make monthly escrow deposits for taxes, insurance
and a reserve for the replacement of project assets, and are subject to
restrictions as to operating policies, rental charges, operating expenditures
and distributions to partners.

           Approximate maturities of mortgage notes payable for the next five
years and thereafter are as follows:

6.         DEFERRED ACQUISITION NOTES PAYABLE

           The deferred acquisition notes bear interest at the rate of 9% per
annum, compounded semi-annually. These notes are nonrecourse and are
collateralized by partnership interests in all Local Limited Partnerships.
Neither principal nor interest are payable currently; all principal and accrued
interest are payable upon the earlier of the sale, transfer, or refinancing of
the project or 2001. The notes may be prepaid in whole or in part at any time
without penalty.

7.         DUE TO PARTNERS

           Annual partnership administration fees of $30,000 were accrued for
1997, 1996 and 1995. The Local Limited Partnerships paid $15,011, $88,750 and
$15,000 in such fees during 1997, 1996 and 1995, respectively. These fees are
payable to the General Partner without interest from surplus cash available for
distribution to partners. The accumulated fees owed to the General Partner were
$118,114 and $103,125 at December 31, 1997 and 1996, respectively.

           During 1997 and 1996, the General Partner advanced $8,320 and $1,104,
respectively to four and one Local Limited Partnership to fund the Local Limited
Partnership's entity expenses. There were no advances made during 1995. No
repayments were made during 1997 and 1996. During 1995, one Local Limited
Partnership repaid principal and interest of $667 and $205 to the General
Partner. The balance owed to the General Partner by the Local Limited
Partnerships at December 31, 1997 and 1996, was $9,424 and $1,104, respectively.
Interest is charged at a rate equal to the Chase Manhattan Bank prime interest
rate plus 2%. Chase Manhattan Bank prime was 8.5% at December 31, 1997.

           During 1996, one Local Limited Partnership repaid principal and
interest in the amounts of $200 and $107, respectively, to the Partnership. As
of December 31, 1997 and 1996, the Partnership had outstanding advances of
$12,200 to one Local Limited Partnership. Interest is charged at the rate of
Chase Manhattan prime plus 2%. Chase Manhattan Bank prime was 8.5% at December
31, 1997. The advance and interest will be paid in conformity with HUD and/or
other regulatory requirements and applicable partnership agreements.

8.         FEDERAL AND STATE INCOME TAXES

           The Local Limited Partnerships are not taxed on their income. The
partners are taxed in their individual capacities upon their distributive share
of the Local Limited Partnerships' taxable income and are allowed the benefits
to be derived from offsetting their distributive share of the tax losses against
taxable income from other sources subject to passive loss rule limitations. The
taxable income or loss differs from amounts included in the statement of
operations primarily because of different methods used in determining
depreciation expense for tax purposes. The tax loss is allocated to partner
groups in accordance with Section 704(b) of the Internal Revenue Code and
therefore is not necessarily proportionate to the interest percentage owned.

           For Federal income tax purposes, the Local Limited Partnerships
compute depreciation of the buildings and improvements using the Accelerated
Cost Recovery System (ACRS) and the Modified Accelerated Cost Recovery System
(MACRS), while for financial statements purposes, depreciation is computed using
the straight-line method, assuming a 50-year life from the date of initial
occupancy. Rent received in advance is included as income in determining the
taxable income or loss for Federal income tax purposes, while for financial
statement purposes it is shown as a liability. Other differences result from the
allocation of tax losses in accordance with Section 704(b) of the Internal
Revenue Code.

9.         RELATED PARTY TRANSACTIONS

           An affiliate of the General Partner, NHP Management Company
("NHPMC"), formerly a wholly owned subsidiary of NHP Incorporated ("NHPI"), is
the project management agent for the projects operated by the Local Limited
Partnerships, except for Royal Towers which changed management agent on November
1, 1996. During May 1997, AIMCO acquired approximately 51% of the voting stock
of NHPI. An additional 3% of the voting stock was acquired by AIMCO in August
1997. On December 8, 1997, the NHPI stockholders elected to merge with AIMCO.
After the merger, NHPMC became a wholly owned subsidiary of AIMCO. NHPMC and
other affiliates of NCHP earned $494,836, $517,575 and $501,645 from the Local
Limited Partnerships for management fees and other services provided to the
Local Limited Partnerships during 1997, 1996 and 1995, respectively. At December
31, 1997 and 1996, amounts due NHPMC and unpaid by the Local Limited
Partnerships amounted to $4,920 and $163,637, respectively.

           Personnel working at the project sites, which are managed by NHPMC,
were employees of NHPI during the period January 1, 1996 through December 8,
1997 and became employees of NHPMC (as a successor employer) as of December 8,
1997 and, therefore, the projects reimbursed NHPI and NHPMC for the actual
salaries and related benefits. Prior to January 1, 1996, project employees were
employees of NCHP. Total reimbursements earned for salaries and benefits for the
years ended December 31, 1997, 1996 and 1995, were approximately $462,000,
$714,000 and $642,000, respectively. At December 31, 1997 and 1996 account
payable included $501 and $16,413 due to NHPMC and NCHP, respectively.

10.        NON-CASH INVESTING ACTIVITIES

           At December 31, 1997, three of the Local Limited Partnerships had
purchased $136,785 in additions to rental property and at December 31, 1996, two
Local Limited Partnership had purchased $21,945 of additions to rental property
which are included in trade payables.

11.        FUTURE OPERATIONS AND CASH FLOWS

           One Local Limited Partnership, Royal Towers Limited Partnership, has
a significant amount of payables and only limited resources with which to pay
such items, which raises substantial doubt about the Royal Towers Limited
Partnership's ability to continue as a going concern. Royal Towers Limited
Partnership continued existence as a going concern is dependent upon maintaining
positive cash flows from operations or obtaining additional fundings from
partners if positive cash flows are not maintained. The General Partner's
intentions are to continue managing the property prudently so that it can
maintain positive cash flows and decrease its debts.

           The total assets, deficit, revenues and net loss of Royal Towers
represent 18%, 37%, 16% and 39% of the applicable amounts included in the
accompanying combined financial statements as of December 31, 1997 and for the
year then ended.

12.        DRUG ELIMINATION GRANT PROGRAM

           Two Local Limited Partnerships have entered into grant agreements
with HUD under the Drug Elimination Grant Program (the "Program") to assist in
the elimination of illegal drugs and the associated crime at the properties. The
grant agreements are dated August 1993 and July 1994, and the amounts awarded
are $175,000 and $164,387, respectively. During 1995, one of the Local Limited
Partnerships received $156,034 for costs incurred under the program, of which
$35,167 is included in miscellaneous operating expenses and $120,867 has been
capitalized in rental property.

13.        EXTRAORDINARY ITEM

           At December 31, 1996, the Royal Towers Limited Partnership had
accrued costs due to NHPMC consisting of management fees, bookkeeping and
accounting fees, payroll and miscellaneous reimbursement items. In addition to
the $131,027 shown as due to management agent on the 1996 combined statements of
financial position, there was $36,735 due to NHPMC included in trade payables.
During 1997, NHPMC informed Royal Towers Limited Partnership that these amounts
totaling $167,762 do not have to be paid and therefore this amount is shown as
an extraordinary gain in the accompanying 1997 combined statements of
operations.

14.        IMPAIRMENT LOSS ON RENTAL PROPERTY

           In March 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 121 "Accounting For The
Impairment of Long-Lived Assets And For Long-Lived Assets To Be Disposed Of"
(the "Statement") effective for financial statements for fiscal years beginning
after December 15, 1995. This Statement requires an impairment loss to be
recognized if the sum of estimated future cash flows (undiscounted and without
interest charges) is less than the carrying amount of rental property. The
impairment loss would be the amount by which the carrying value exceeds the fair
value of the rental property. If the rental property is to be disposed of, fair
value is calculated net of costs to sell.

           During 1996, Royal Towers Limited Partnership and Loring Tower
Associates Limited Partnership, recognized impairment losses on their rental
properties in the amounts of $1,960,000 and $2,700,000, respectively. Because
the Local Limited Partnerships' deferred acquisition notes are due March 27,
2001(Note 6), the Local Limited Partnerships estimated net cash flow is only for
the period January 1, 1997 to March 27, 2001. As a result of this limited


                                       55

holding period, the estimated net cash flow was less than the carrying amount at
December 31, 1996. The Local Limited Partnerships used the Direct Capitalization
Method to estimate the fair value of the rental property. Using this Method,
estimated annual cash flow generated by the property is divided by an overall
capitalization rate to estimate the rental property's fair value.

           Additionally, regardless of whether a impairment loss of an
individual property has been recorded or not, the carrying value of each of the
rental properties may still exceed their fair market value as of December 31,
1997. Should a Local Limited Partnership be forced to dispose of any of its
properties, it could incur a loss.

15.        FAIR VALUE OF FINANCIAL INSTRUMENTS

           FASB Statement No. 107, "Disclosures About Fair Value of Financial
Instruments," requires disclosure of fair value information about financial
instruments, when it is practicable to estimate that value. The mortgage notes
payable are insured by the FHA and are secured by the rental property. The
operations generated by the rental property are subject to various government
rules, regulations and restrictions which make it impracticable to obtain the
information to estimate the fair value of the mortgage note and the partner
loans and related accrued interest. For the deferred acquisition notes and
related accrued interest, a reasonable estimate of fair value could not be made
without incurring excessive costs. The carrying amount of other assets and
liabilities reported on the statement of financial position that require such
disclosure approximates fair value.

16.        FIRE LOSS CONTINGENCY

           On December 1, 1996, a fire occurred at the Royal Towers Limited
Partnership project site. Management believes that all damages will be recovered
through insurance proceeds less a $2,500 deductible. As of December 31, 1996, an
insurance receivable was recorded for $1,880,289 which includes $1,784,685 for
fire loss damages net of the deductible, and $95,604 for loss of rent for the
month of December, 1996.

           During 1997, Royal Towers Limited Partnership received approximately
$2,756,000 in insurance proceeds relating to the fire and used approximately
$2,485,000 of these proceeds as of December 31, 1997. Use of the remaining
$271,000 held in escrow by the mortgage company and the final insurance award
have not been determined or approved.

           During 1997, HUD approved withdrawals of $249,365 from the reserve
for replacements to pay outstanding fire related payables. This is considered a
loan from the reserve for replacements and must be repaid to the reserve for
replacements when reimbursement is received from the insurance company.

           In addition to amounts reimbursed from insurance proceeds, Royal
Towers Limited Partnership has incurred costs of $190,761 which are fire related
and have been included in the accompanying combined statements of operations and
$95,164 of costs which have been capitalized. Royal Towers Limited Partnership
anticipates that an additional $1,000,000 is needed to repair the property to
its pre-fire condition and is seeking insurance funds to fund such costs.
