PART I

This Form 10-K contains forward-looking statements within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. Actual results could differ materially from those projected in the
forward-looking statements as a result of a number of factors, including those
identified herein.

ITEM 1. BUSINESS

Krupp Insured Mortgage Limited Partnership (the "Partnership") is a
Massachusetts limited partnership which was formed on March 21, 1988. The
Partnership raised approximately $299 million through a public offering of
limited partner interests evidenced by units of depositary receipts ("Units"),
and used the proceeds available for investment primarily to acquire
participating insured mortgages ("PIMs") and mortgage-backed securities ("MBS").
The Partnership considers itself to be engaged only in the industry segment of
investment in mortgages.

The Partnership's investments in PIMs on multi-family residential properties
consist of a MBS or an insured mortgage loan (collectively, the "insured
mortgage") guaranteed or insured as to principal and basic interest. These
insured mortgages were issued or originated under or in connection with the
housing programs of the Government National Mortgage Association ("GNMA"),
"Fannie Mae" or the Department of Housing and Urban Development ("HUD"). PIMs
provide the Partnership with monthly payments of principal and basic interest
and also may provide the Partnership with participation in the current revenue
stream and in residual value, if any, from the sale or other realization of the
underlying property. The borrower conveys these rights to the Partnership
through a subordinated promissory note and mortgage. The participation features
are neither insured nor guaranteed.

The Partnership also acquired MBS collateralized by single-family mortgage loans
issued or originated by Fannie Mae or the Federal Home Loan Mortgage Corporation
("FHLMC"). Fannie Mae and FHLMC guarantee the principal and basic interest of
the Partnership's FNMA and FHLMC MBS, respectively.

Proceeds received from prepayments or other realizations of mortgage assets will
be distributed by the Partnership to investors through quarterly or special
distributions.

Although the Partnership will terminate no later than December 31, 2028, the
value of the PIMs may be realized by the Partnership through repayment or sale
as early as ten years from the dates of the closing of the permanent loans and
the Partnership may realize the value of all its other investments within that
time frame. Therefore, it is anticipated that dissolution of the Partnership
could occur significantly prior to December 31, 2028.

The Partnership's investments are not expected to be subject to seasonal
fluctuations. However, the future performance of the Partnership will depend
upon certain factors which cannot be predicted. In addition, any ultimate
realization of the participation features of the PIMs will be subject to similar
risks associated with equity real estate investments, including: reliance on the
owner's operating skills, ability to maintain occupancy levels, control
operating expenses, maintain the property and provide adequate insurance
coverage; adverse changes in general economic conditions, adverse local
conditions, and changes in governmental regulations, real estate zoning laws, or
tax laws; and other circumstances over which the Partnership may have little or
no control.

The requirements for compliance with federal, state and local regulations to
date have not had an adverse effect on the Partnership's operations, and the
Partnership does not presently anticipate any adverse effect in the future.

As of December 31, 1999 there were no personnel directly employed by the
Partnership.

ITEM 2. PROPERTIES

None.

ITEM 3. LEGAL PROCEEDINGS

There are no material pending legal proceedings to which the Partnership is a
party or to which any of its securities is the subject.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
None.


PART II

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
MATTERS

There currently is no established trading market for the Units.

The number of investors holding Units as of December 31, 1999 was approximately
13,200. One of the objectives of the Partnership is to provide quarterly
distributions of cash flow generated by its investments in mortgages. The
Partnership presently anticipates that future operations will continue to
generate cash available for distribution.

During 1999, the Partnership made special distributions consisting of principal
proceeds from the Pope Building, Remington, Valley Manor and Cross Creek PIM
Prepayments.

During 1998, the Partnership made special distributions consisting primarily of
principal proceeds from the Deering Place, Southland and Paddock Club Apartments
PIM prepayments.

The Partnership will make special distributions in the future as PIMs prepay or
a sufficient amount of cash is available from MBS and PIM principal collections.



The Partnership made distributions to its Partners during the two years ended
December 31, 1999 and 1998 as follows:

1999 1998

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of
Operations contains forward-looking statements including those concerning
Management's expectations regarding the future financial performance and future
events. These forward-looking statements involve significant risk and
uncertainties, including those described herein. Actual results may differ
materially from those anticipated by such forward-looking statements.

Starting in 1997, the General Partners conducted an assessment of the
Partnership's core internal and external computer information systems to
understand the nature and extent of work required to make its systems Year 2000
ready. The Year 2000 readiness issue was concerned with the inability of
computerized information systems to accurately calculate, store or use a date
after 1999. The General Partners believed that a system failure or
miscalculation could cause disruptions of operations.

As a result of this concern, the General Partners, along with certain
affiliates, upgraded their computer systems including their hardware and
software so they would be Year 2000 ready. In addition, the General Partners
surveyed the Partnership's material third-party service providers and
significant vendors and received assurances that they were Year 2000 ready. The
General Partners also developed contingency plans for all of their
"mission-critical functions" to insure business continuity. As a result of these
efforts and the efforts of third parties, the Year 2000 did not result in any
disruption of activities to the Partnership.



Liquidity and Capital Resources

The most significant demands on the Partnership's liquidity are the regular
quarterly distributions paid to investors of approximately $3.1 million. Funds
used for the investor distributions are generated from interest income received
on the PIMs, MBS, cash and short-term investments and the principal collections
received on the PIMs and MBS. The Partnership funds a portion of the quarterly
distribution from principal collections causing the capital resources of the
Partnership to continually decrease. As a result of the decrease, the total cash
inflows to the Partnership will also decrease, which will result in periodic
adjustments to the distributions paid to investors. The General Partners
periodically review the distribution rate to determine whether an adjustment is
necessary based on projected future cash flows. In general, the General Partners
try to set a distribution rate that provides for level quarterly distributions.
Based on current projections the General Partners believe the Partnership will
need to adjust the current distribution rate of $.21 per Unit per quarter
commencing with the distribution to be paid in May 2000. The General Partners
will determine the revised rate during the first quarter of 2000.

In addition to providing insured or guaranteed monthly principal and basic
interest payments, the Partnership's PIM investments also may provide additional
income through its participation feature in the underlying properties if they
operate successfully. The Partnership may receive a share in any operating cash
flow that exceeds debt service obligations and capital needs or a share in any
appreciation in value when the properties are sold or refinanced. However, this
participation is neither guaranteed nor insured, and it is dependent upon
whether property operations or its terminal value meet certain criteria.

On February 25, 2000 the Partnership received a payoff on the Brookside
Apartments PIM in the amount of $4,531,910. The Borrower defaulted on the first
mortgage loan and Fannie Mae paid off the MBS upon maturity in February 2000.
The Partnership anticipates a first quarter special distribution of $.31 per
unit. The Partnership is pursuing the receipt of approximately $307,000 in
additional income due from the borrower. At this time, it is uncertain if the
Partnership will receive this income.

During December 1999, the Partnership received prepayments on the Salishan,
Saratoga, and Marina Shores Apartments PIMs, and the Patrician MBS. In addition
to the principal proceeds of $14,666,235 from the Salishan PIM, the Partnership
also received $146,662 of prepayment premium income and $311,650 of Shared
Interest Income and Minimum Additional Income. The Partnership received
$6,008,565 of principal proceeds from the Marina Shores PIM along with $176,679
of Shared Appreciation and prepayment premium income. The principal proceeds
from the Saratoga PIM and the Patrician MBS prepayments were $6,204,895 and
$7,830,263, respectively. The Partnership did not receive any additional
interest on the Saratoga prepayment. On January 11, 2000, the Partnership paid a
special distribution of $2.37 per Limited Partner interest from the principal
proceeds, Shared Appreciation and prepayment premium received from these four
payoffs.

In October 1999 the Partnership received a repayment of the Valley Manor
Apartments PIM of $4,425,993. The Partnership did not receive any Additional
Interest as a result of this prepayment because the underlying property's
appraised value did not exceed the threshold required to realize additional
interest. In November 1999 the Partnership paid a special destribution of $.30
per Limited Partner interest from the Valley Manor proceeds. In February 1999,
the Partnership received a payoff of the Pope Building PIM in the amount of
$3,176,761. In addition, the Partnership received $703,860 of Shared
Appreciation and prepayment premium income and $218,578 of Shared Income and
Minimum Additional Interest upon the payoff of the underlying mortgage. During
March 1999, the Partnership received a payoff of the Remington PIM in the amount
of $12,199,298. The payoff was the result of a default on the underlying loan
which resulted in the Partnership receiving all of the outstanding principal
balance under the insurance feature of the PIM. However, due to the default the
Partnership did not receive any participation income from this PIM. During May
1999, the Partnership paid a special distribution of $1.08 per Limited Partner
interest from the principal proceeds received from the Remington and Pope
Building PIMs and the Shared Appreciation and prepayment premium proceeds
received from the Pope Building PIM.

During January 1999, the Partnership paid a special distribution of $.66 per
Limited Partner Interest from the principal proceeds and prepayment premium
received from the Cross Creek PIM in 1998. The prepayment of the Cross Creek PIM
remaining principal balance amounted to $9,414,586 with Additional Income (in
lieu of a prepayment premium) of approximately $318,000 was received along with
Shared Income of approximately $60,000.


The Partnership made two special distributions during 1998. On July 27, 1998 and
August 26, 1998, the Partnership received a partial prepayment and final
prepayment of approximately $654,000, and $2,985,000, respectively, for the
Deering Place Apartments PIM. In addition to the principal prepayment the
Partnership received minimum additional interest and shared interest income of
$90,195 and a prepayment premium of $268,638. The Partnership distributed the
capital transaction proceeds from this prepayment to investors through a special
distribution on September 18, 1998 in the amount of $.27 per Limited Partner
interest. In January 1998, a $1.12 per Unit special distribution was made with
the prepayment proceeds of the Paddock Club and Southland Station PIMs that were
received in 1997. During the fourth quarter of 1997, the Partnership received
the principal repayments totaling $15.2 million when those two properties were
sold. In addition to the principal repayments, the Partnership received a total
of $380,000 of accrued Additional Interest from both properties and $565,000 of
Shared Appreciation Income on Southland Station and a $895,000 prepayment
premium on Paddock Club.

Most of the properties had stable operating results in 1999. High occupancy
rates were maintained at more than half of the properties due to stable or
improving markets. However, due to poor operating performance, the General
Partners are closely monitoring the Wildflower apartments PIM property which is
located in the thriving Las Vegas market. Wildflower has suffered a dramatic
decline in occupancy to the mid-80% range at year-end that is not representative
of the rest of the market. Wildflower, which offers only a basic apartment, does
not compete successfully with the newer apartment properties, which have many
amenities that have been built since the strong Las Vegas economy has fostered a
tremendous construction boom.

During the first five years, owners are prohibited from prepaying the first
mortgage loans underlying the PIMs. During the second five years, owners may
prepay the loans by incurring a prepayment penalty. The Partnership has the
option to call certain PIMs by accelerating their maturity if they are not
prepaid by the tenth year after permanent funding. The Partnership will
determine the merits of exercising the call option for each PIM as economic
conditions warrant. Such factors as the condition of the asset, local market
conditions, the interest rate environment and availability of financing will
affect those decisions.

Assessment of Credit Risk

The Partnership's investments in mortgages are guaranteed or insured by Fannie
Mae, GNMA, FHLMC or HUD and therefore the certainty of their cash flows and the
risk of material loss of the amounts invested depends on the creditworthiness of
these entities.

Fannie Mae is a federally chartered private corporation that guarantees
obligations originated under its programs. FHLMC is a federally chartered
corporation that guarantees obligations originated under its programs and is
wholly-owned by the twelve Federal Home Loan Banks. These obligations are not
guaranteed by the U.S. Government or the Federal Home Loan Bank Board. GNMA
guarantees the full and timely payment of principal and basic interest on the
securities it issues, which represent interests in pooled mortgages insured by
HUD. Obligations insured by HUD, an agency of the U.S. Government, are backed by
the full faith and credit of the U.S. Government.

The Partnership includes in cash and cash equivalents approximately $38.9
million of commercial paper, which is issued by entities with a credit rating
equal to one of the top two rating categories of a nationally recognized
statistical rating organization.

Interest Rate Risk

The Partnership's primary market risk exposure is to interest rate risk, which
can be defined as the exposure of the Partnership's net income, comprehensive
income or financial condition to adverse movements in interest rates. At
December 31, 1999, the Partnerships PIMs, PIMIs and MBS comprise the majority of
the Partnership's assets. As such, decreases in interest rates may accelerate
the prepayment of the Partnership's investments. The Partnership does not
utilize any derivatives or other instruments to manage this risk as the
Partnership plans to hold all of its investments to expected maturity.

The Partnership monitors prepayments and considers prepayment trends, as well as
distribution requirements of the Partnership, when setting regular dividend
distribution policy. For MBS, the fund forecasts prepayments based on trends in
similar securities as reported by statistical reporting entities such as
Bloomberg. For PIMs and PIMIs, the Partnership incorporates prepayment
assumptions into planning as individual properties notify the Partnership of the
intent to prepay or as they mature.


The table below provides information about the Company's financial instruments
that are sensitive to changes in interest rates. For mortgage investments, the
table presents principal cash flows and related weighted average interest rates
by expected maturity dates. The expected maturity date is contractual maturity
adjusted for expectations of prepayments.

Results of Operations

The following discussion relates to the operation of the Partnership during the
years ended December 31, 1999, 1998 and 1997.




(Amounts in thousands)
1999 1998 1997

Interest income on PIMs:

Basic interest $ 6,325 $ 9,089 $ 10,887
Participation interest 1,666 865 3,710
Interest income on MBS 1,206 1,595 1,493
Other interest income 609 406 589
Partnership expenses (1,006) (1,219) (1,574)
Amortization of prepaid fees and
expenses (1,298) (1,636) (2,917)

Net income $ 7,502 $ 9,100 $ 12,188


Net income decreased by approximately $1,598,000 during 1999 as compared to
1998. This decrease was due primarily to lower basic interest on PIMs and
interest income on MBS in the amounts of approximately $2,764,000 and $389,000,
respectively. This was partially offset by an increase in Participation interest
of approximately $801,000 and decreases in asset management fees and
amortization expense, in the amounts of approximately $215,000 and $338,000,
respectively. The reduction in basic interest on PIMs is due to the payoff of
the Remington, Pope Building and Valley Manor PIMs in 1999 and the payoffs of
the Deering Place and Cross Creek PIMs in 1998. The decrease in MBS interest
income was due to the on-going prepayment of the Partnership's single-family
MBS. The increase in participation interest on PIMs was due primarily to the
receipt of $922,000, $458,000 and $177,000 of participation interest from the
Pope Building, Salishan and Marina Shores PIM prepayments as compared to the
$359,000 and $378,000 received in 1998 from the Deering Place and Cross Creek
PIM payoffs, respectively. Also, asset management fees decreased during 1999 as
compared to 1998 due to the prepayments and principal collections reducing the
Partnership's mortgage investments. Amortization expense was greater in 1998 as
a result of the full amortization of the remaining prepaid fees and expenses of
the Deering Place and Cross Creek PIMs and the Patrician multi-family MBS in
1998 exceeding the amount of amortization resulting from the PIM prepayments
occurring in 1999.


Net income decreased by approximately $3,088,000 during 1998 as compared to
1997. The decrease was primarily due to lower basic interest and participation
interest. The decrease in basic interest of approximately $1,798,000 was a
result of the Deering Place and Cross Creek PIM prepayments during 1998, and the
prepayments of the Rock Creek, Silver Springs, Hampton Ridge, Southland Station
and Paddock Club PIM's during 1997 and the Patrician PIM converting to a
non-participating insured mortgage during the fourth quarter of 1997.
Participation interest declined by approximately $2,845,000 as a result of the
significant level of PIM prepayments in 1997 mentioned above exceeding the level
of participation interest received when the Deering Place and Crosscreek PIM
prepayments occurred in 1998. Other interest income decreased in 1998 as
compared to 1997 due to lower average short-term investment balances during 1998
when compared to 1997. Amortization expense decreased for the twelve month
period ending 1998 as compared to the same period in 1997 as a result of the
Partnership fully amortizing the costs associated with the PIMs that were
prepaid in 1997. The decrease in Partnership expenses was due primarily to lower
asset management fees resulting from the prepayments of the Deering Place and
Crosscreek PIMs in 1998 and the Rock Creek, Silver Springs, Hampton Ridge,
Paddock Club and Southland PIMs in 1997. In addition, lower transfer agent costs
were incurred in 1998 and a rebate was received for expense reimbursements
related to 1997 during the second quarter of 1998.

KRUPP INSURED MORTGAGE LIMITED PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS, Continued


A. Organization

Krupp Insured Mortgage Limited Partnership (the "Partnership") was formed on
March 21, 1988 by filing a Certificate of Limited Partnership in The
Commonwealth of Massachusetts. The Partnership was organized for the purpose of
investing in multi-family loans and mortgage backed securities. The Partnership
issued all of the General Partner Interests to two General Partners in exchange
for capital contributions aggregating $3,000. Krupp Plus Corporation and
Mortgage Services Partners Limited Partnership are the General Partners of the
Partnership and Krupp Depositary Corporation is the Corporate Limited Partner.
Except under certain limited circumstances upon termination of the Partnership,
the General Partners are not required to make any additional capital
contributions. The Partnership terminates on December 31, 2028, unless
terminated earlier upon the occurrence of certain events as set forth in the
Partnership Agreement.

The Partnership commenced the public offering of Units on July 22, 1988 and
completed its public offering on May 23, 1990 having sold 14,956,696 Units for
$298,678,321 net of purchase volume discounts of $457,599. In addition, Krupp
Depository owns one hundred units.

B. Significant Accounting Policies

The Partnership uses the following accounting policies for financial reporting
purposes, which may differ in certain respects from those used for federal
income tax purposes (see Note G):

MBS

The Partnership, in accordance with Financial Accounting Standards Board's
Special Report on Statement 115, "Accounting for Certain Investments in Debt and
Equity Securities" (FAS 115), classifies its MBS portfolio as
available-for-sale. As such the Partnership carries its MBS at fair market value
and reflects any unrealized gains (losses) as a separate component of Partners'
Equity. The Partnership amortizes purchase premiums or discounts over the life
of the underlying mortgages using the effective interest method.

Effective January 1, 1998, the Partnership adopted Statement of Financial
Accounting Standards No. 130, 'Reporting Comprehensive Income' (FAS 130). FAS
130 established standards for reporting and displaying comprehensive income and
its components. FAS 130 requires comprehensive income and its components, as
recognized under accounting standards, to be displayed in a financial statement
with the same prominence as other financial statements, if material.
Accordingly, unrealized gains (losses) on the Partnership's available-for sale
securities have been included in other comprehensive income.

PIMs

The Partnership accounts for its MBS portion of a PIM in accordance with FAS 115
under the classification of held to maturity. The Partnership carries the
Government National Mortgage Association (GNMA) or Fannie Mae MBS at amortized
cost.

The insured mortgage portion of its Federal Housing Administration (FHA) PIM is
carried at amortized cost. The Partnership holds this FHA insured mortgage at
amortized cost since the loan is fully insured by the FHA.

Basic interest on PIMs is recognized based on the stated rate of the FHA
mortgage loan (less the servicer's fee) or the stated coupon rate of the GNMA or
Fannie Mae MBS. Participation interest is recognized as earned and when deemed
collectible by the Partnership.



Continued


B. Significant Accounting Policies, continued

Cash and Cash Equivalents

The Partnership includes all short-term investments with maturities of three
months or less from the date of acquisition in cash and cash equivalents. The
Partnership invests its cash primarily in commercial paper and money market
funds with a commercial bank and has not experienced any loss to date on its
invested cash.

Prepaid Fees and Expenses

Prepaid fees and expenses represent prepaid acquisition fees, expenses and
prepaid participation servicing fees paid for the acquisition and servicing of
PIMs. The Partnership amortizes prepaid acquisition fees and expenses using a
method that approximates the effective interest method over a period of ten to
twelve years, which represents the actual maturity or anticipated repayment of
the underlying mortgage. Acquisition expenses incurred on potential acquisitions
which were not consummated were charged to operations.

The Partnership amortizes prepaid participation servicing fees using a method
that approximates the effective interest method over a ten-year period beginning
at final endorsement of the loan if a Department of Housing and Urban
Development ("HUD") loan or GNMA loan and at closing if a Fannie Mae loan.

Income Taxes

The Partnership is not liable for federal or state income taxes as Partnership
income is allocated to the partners for income tax purposes. In the event that
the Partnership's tax returns are examined by the Internal Revenue Service or
state taxing authority and the examination results in a change in Partnership
taxable income, such change will be reported to the partners.

Estimates and Assumptions

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

C. PIMs

At December 31, 1999 and 1998, the Partnership had investments in six PIMs and
twelve PIMs, respectively. The Partnership's PIMs consist of (a) a GNMA or
Fannie Mae MBS representing the securitized first mortgage loan on the
underlying property or a sole participation interest in the mortgage loan
originated under HUD's FHA lending program (collectively the "insured
mortgages"), and (b) participation interests in the revenue stream and
appreciation of the underlying property above specified base levels. The
borrower conveys these participation features to the Partnership generally
through a subordinated promissory note and mortgage (the "Agreement").

The Partnership receives guaranteed monthly payments of principal and interest
on the GNMA and Fannie Mae MBS, and HUD insures the FHA mortgage loan. The
borrower usually cannot prepay the first mortgage loan during the first five
years and may prepay the first mortgage loan thereafter subject to a 9%
prepayment premium in years six through nine, a 1% prepayment premium in year
ten and no prepayment premium thereafter. The Partnership may receive interest
related to its participation interests in the underlying property, however,
these amounts are neither insured nor guaranteed.

Generally, the participation features consist of the following: (i) "Minimum
Additional Interest" which is at the rate of .5% to 1% per annum calculated on
the unpaid principal balance of the first mortgage on the underlying property,
(ii) "Shared Income Interest" which is 25% to 35% of the monthly gross rental
income generated by the underlying property in excess of a specified base, but
only to the extent that it exceeds the amount of Minimum Additional Interest
earned
Continued


C. PIMs, continued

during such month, (iii) "Shared Appreciation Interest" which is 25% to 35% of
any increase in the value of the underlying property in excess of a specified
base. Payment of participation interest from the operations of the property is
limited in any year to 50% of net revenue or surplus cash as defined by Fannie
Mae or HUD, respectively. The aggregate amount of Minimum Additional Interest,
Shared Income Interest and Shared Appreciation Interest payable by the
underlying borrower on the maturity date generally cannot exceed 50% of any
increase in value of the property.

However, generally any net proceeds from the sale or refinancing of the property
will be available to satisfy any accrued but unpaid Shared Income or Minimum
Additional Interest.

Shared Appreciation Interest is payable when one of the following occurs: (1)
the sale of the underlying property to an unrelated third party on a date which
is later than five years from the date of the Agreement, (2) the maturity date
or accelerated maturity date of the Agreement, or (3) prepayment of amounts due
under the Agreement and the insured mortgage.

The Partnership, upon giving twelve months written notice, can accelerate the
maturity date of the Agreement to a date not earlier than ten years from the
date of the Agreement for (a) the payment of all participation interest due
under the Agreement as of the accelerated maturity date, or (b) the payment of
all participation interest due under the Agreement plus all amounts due on the
first mortgage note on the property.

During December 1999, the Partnership received prepayments on the Salishan,
Saratoga, and Marina Shores Apartments PIMs, and the Patrician MBS. In addition
to the principal proceeds from the Salishan PIM of $14,666,235, the Partnership
received $146,662 of prepayment premium income and $311,650 of Shared Interest
Income and Minimum Additional Income. The Partnership received $6,008,565 of
principal proceeds from the Marina Shores PIM along with $176,679 of Shared
Appreciation and prepayment premium income. The principal proceeds from the
Saratoga PIM and the Patrician MBS prepayments were $6,204,895 and $7,830,263,
respectively. The Partnership did not receive any additional interest on the

Profits from Partnership operations and Distributable Cash Flow are allocated
97% to the Unitholders and Corporate Limited Partner (the "Limited Partners")
and 3% to the General Partners.

Upon the occurrence of a capital transaction, as defined in the Partnership
Agreement, net cash proceeds and profits from the capital transaction will be
distributed first, to the Limited Partners until they have received a return of
their total invested capital, second, to the General Partners until they have
received a return of their total invested capital, third, 99% to the Limited
Partners and 1% to the General Partners until the Limited Partners receive an
amount equal to any deficiency in the 11% cumulative return on their invested
capital that exists through fiscal years prior to the date of the capital
transaction, fourth, to the class of General Partners until they have received
an amount equal to 4% of all amounts of cash distributed under all capital
transactions and fifth, 96% to the Limited Partners and 4% to the General
Partners. Losses from a capital transaction will be allocated 97% to the Limited

G. Federal Income Taxes




The reconciliation of the net income reported in the accompanying statement of
income with the income reported in the Partnership's 1999 federal income tax
return is as follows:


Net income per statement of income $ 7,502,317

Book to tax difference for timing of PIM
income (263,674)
Book to tax difference for amortization of
prepaid expenses and fees (1,791,904)

Net income for federal income tax purposes $ 5,446,739






The allocation of the 1999 net income for federal income tax purposes is as
follows:

Portfolio
Income


Unitholders $5,314,117
Corporate Limited Partner 36
General Partners 132,586

$5,446,739


For the years ended December 31, 1999, 1998 and 1997 the average per unit income
to the Unitholders for federal income tax purposes was $.36, $.60 and $.83
respectively.

The basis of the Partnership's assets for financial reporting purposes is less
than its tax basis by approximately $2,634,000 and $3,823,000 at December 31,
1999 and 1998, respectively. The basis of the Partnership's liabilities for
financial reporting purposes are less than its tax basis by approximately
$265,000 and $0 at December 31, 1999 and 1998, respectively.

H. Fair Value Disclosure of Financial Instruments

The Partnership uses the following methods and assumptions to estimate the fair
value of each class of financial instruments:

Cash and cash equivalents

The carrying amount approximates fair value due to the short maturity of those
instruments.

MBS

The Partnership estimates the fair value of MBS based on quoted market prices.
Based on the estimated fair value determined using these methods and
assumptions, the Partnership's investments in MBS had gross unrealized gains and
losses of approximately $140,000 and $136,000 at December 31, 1999 and $645,000
and $0 at December 31, 1998.


Continued



H. Fair Value Disclosure of Financial Instruments, continued

PIMs

There is no active trading market for these investments. Management estimates
the fair value of the PIMs using quoted market prices of MBS having the same
stated coupon rate. Management does not include any participation income in the
Partnership's estimated fair value arising from appreciation of the properties,
because Management does not believe it can predict the time of realization of
the feature with any certainty. Based on the estimated fair value determined
using these methods and assumptions, the Partnership's investments in PIMs had
gross unrealized gains and losses of approximately $168,000 and $311,000,
respectively, at December 31, 1999, and gross unrealized gains of approximately
$2,527,000 at December 31, 1998.



At December 31, 1999 and 1998, the estimated fair values of the Partnership's
financial instruments are as follows:

(Amounts in thousands)
1999 1998
Fair Carrying Fair Carrying
Value Value Value Value


Cash and cash equivalents $ 39,435 $ 39,435 $ 15,117 $ 15,117

MBS 7,460 7,460 18,807 18,807

PIMS 51,247 51,390 101,478 98,951

$ 98,142 $ 98,285 $135,402 $132,875


I. Subsequent Event

On February 25, 2000 the Partnership received a payoff on the Brookside
Apartments PIM in the amount of $4,531,910. The Borrower defaulted on the first
mortgage loan and Fannie Mae paid off the MBS upon maturity in February 2000.
The Partnership anticipates a first quarter special distribution of $.31 per
unit. The Partnership is pursuing the receipt of approximately $307,000 in
additional income due from the borrower. At this time, it is uncertain if the
Partnership will receive this income.
