Item 1. FINANCIAL STATEMENTS

This Form 10-Q 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. When used in this Form 10-Q, the words "believes," "anticipates,"
"expects," "plans," "intends," "estimates," "continue," "may" or "will" (or the
negative of such words) and similar expressions are intended to identify
forward-looking statements. Such statements are subject to a number of risks and
uncertainties, including but not limited to the following: federal, state or
local regulations; adverse changes in general economic or local conditions;
pre-payments of mortgages; failure of borrowers to pay participation interests
due to poor operating results of properties underlying the mortgages; uninsured
losses and potential conflicts of interest between the Partnership and its
Affiliates, including the General Partners. The Company's filings with the
Securities and Exchange Commission, including its Annual Report on Form 10-K for
the year ended December 31, 2003, contain additional information concerning such
risk factors. Actual results in the future could differ materially from those
described in any forward-looking statements as a result of the risk factors set
forth above, and the risk factors described in the Annual Report.

                         NOTES TO FINANCIAL STATEMENTS

1.    Accounting Policies

      Certain information and footnote disclosures normally included in
      financial statements prepared in accordance with accounting principles
      generally accepted in the United States of America have been condensed or
      omitted in this report on Form 10-Q pursuant to the Rules and Regulations
      of the Securities and Exchange Commission. However, in the opinion of the
      general partners, Krupp Plus Corporation and Mortgage Services Partners
      Limited Partnership (collectively the "General Partners"), of Krupp
      Insured Plus-III Limited Partnership (the "Partnership"), the disclosures
      contained in this report are adequate to make the information presented
      not misleading. See Notes to Financial Statements included in the
      Partnership's Form 10-K for the year ended December 31, 2003 for
      additional information relevant to significant accounting policies
      followed by the Partnership.

      In the opinion of the General Partners of the Partnership, the
      accompanying unaudited financial statements reflect all adjustments
      (consisting of only normal recurring accruals) necessary to present fairly
      the Partnership's financial position as of March 31, 2004, and its results
      of operations for the three months ended March 31, 2004 and 2003 and its
      cash flows for the three months ended March 31, 2004 and 2003.

      The results of operations for the three months ended March 31, 2004 are
      not necessarily indicative of the results which may be expected for the
      full year. See Management's Discussion and Analysis of Financial Condition
      and Results of Operations included in this report.

2.    PIMs

      At March 31, 2004, the Partnership's remaining PIM had a fair value of
      approximately $12,750,039. Fair value assumes that the GNMA MBS portion of
      the PIM could be sold at prices that MBS with similar interest rates are
      currently being sold at. Fair value does not include any value for the
      participation feature. The PIM matures in 2031 and at March 31, 2004 was
      not delinquent as to principal or interest.

3.    MBS

      At March 31, 2004, the Partnership's MBS portfolio had an amortized cost
      of $973,804 and gross unrealized gains of $96,270. The portfolio has
      maturities ranging from 2016 to 2024.

4.    Changes in Partners' Equity

      A summary of changes in Partners' Equity for the three months ended March
      31, 2004 is as follows:

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

The following discussion and analysis should be read in conjunction with the
financial statements and accompanying notes contained in the Partnership's 2003
Annual Report on Form 10-K and in this report on Form 10-Q.

Certain statements in this Management's Discussion and Analysis of Financial
Condition and Results of Operations and elsewhere in this Form 10-Q constitute
"forward-looking statements" within the meaning of the Federal Private
Securities Litigation Reform Act of 1995. These forward-looking statements
involve known and unknown risks, uncertainties and other factors which may cause
the Partnership's actual results, performance or achievements to be materially
different from any future results, performance or achievements expressed or
implied by these forward-looking statements. These factors include, among other
things, federal, state or local regulations; adverse changes in general economic
or local conditions; pre-payments of mortgages; failure of borrowers to pay
participation interests due to poor operating results at properties underlying
the mortgages; uninsured losses and potential conflicts of interest between the
Partnership and its Affiliates, including the General Partners.

Liquidity and Capital Resources

At March 31, 2004, the Partnership had liquidity consisting of cash and cash
equivalents of approximately $1.3 million as well as the cash flow provided by
its investments in the remaining PIM and MBS. The Partnership anticipates that
these sources will be adequate to provide the Partnership with sufficient
liquidity to meet its obligations as well as to provide distributions to its
investors.

The most significant demand on the Partnership's liquidity is the quarterly
distribution paid to investors, of approximately $383,000, which represents the
current quarterly distribution rate of $0.03 per Limited Partner interest. Funds
for quarterly distributions come from interest income received on the remaining
PIM and MBS and cash and cash equivalents, net of operating expenses, and the
principal collections received on the remaining PIM and MBS. The portion of
distributions attributable to the principal collections and cash reserves
reduces the capital resources of the Partnership. As the capital resources
decrease, the total cash flows to the Partnership will also decrease and over
time 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. To the extent that quarterly distributions do not
fully utilize the cash available for distributions and cash balances increase,
the General Partners may adjust the distribution rate or distribute such funds
through a special distribution. Based on current projections, the General
Partners have determined that the Partnership will continue to pay a
distribution rate of $0.03 per Limited Partner interest per quarter for the near
future.

In addition to providing insured and guaranteed monthly principal and basic
interest payments from the GNMA MBS portion of the PIM, the Partnership's
remaining PIM investment also may provide additional income through a
participation interest in the underlying property. 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 property is 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.

The Partnership's only remaining PIM investment is backed by the first mortgage
loan on Harbor Club. In response to more competitive market conditions brought
on by low interest rates and low unemployment, which encourages more home
ownership, Harbor Club began offering generous concessions to attract residents.
Although physical occupancy is in the mid 90% range, the economic occupancy
continues to hover in the mid 80% range as a result of the concessions. Due to
the effect of the low occupancy on property operations and cash flow, the
General Partners do not expect Harbor Club to pay the Partnership any
participation interest during 2004.

Presently, the General Partners expect the property to be refinanced during
2004. There are no contractual obligations remaining that would prevent a
repayment of the first mortgage loan. In the event that the Harbor Club PIM is
paid off, the Partnership would then commence an orderly liquidation of the
remaining assets of the Partnership and subsequently pay a liquidating
distribution.

In the event that the remaining PIM does not pay off as discussed above, the
Partnership does have the option to call this PIM by accelerating its maturity.
If the call feature is exercised then the insurance feature of the loan would be
canceled. Therefore, the Partnership will determine the merits of exercising the
call option 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 this decision.

Critical Accounting Policies

The Partnership's critical accounting policies relate primarily to revenue
recognition related to the Partnership's remaining PIM investment and the
carrying value of the MBS. The Partnership's policies are as follows:

The Partnership accounts for its MBS portion of its PIM investment in accordance
with Financial Accounting Standards Board's Statement 115, "Accounting for
Certain Investments in Debt and Equity Securities" ("FAS 115"), under the
classification of held to maturity as this investment has a participation
feature. As a result, the Partnership would not sell or otherwise dispose of the
MBS. Accordingly, the Partnership has both the intention and ability to hold
this investment to expected maturity. The Partnership carries this MBS at
amortized cost. The Partnership, in accordance with FAS 115, classifies its MBS
portfolio as available-for-sale. The Partnership classifies its MBS portfolio as
available-for-sale as a portion of the MBS portfolio may remain after all of the
PIMs pay off. It will be necessary to then sell the remaining MBS portfolio at
that time in order to close out the Partnership. In addition, other situations
such as liquidity needs could arise which would necessitate the sale of a
portion of the MBS portfolio. 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.

Basic interest on PIMs is recognized based on the stated coupon rate of the GNMA
MBS. The Partnership recognizes interest related to the participation features
when the amount becomes fixed and the transaction that gives rise to such amount
is finalized, cash is received and all contingencies are resolved. This could be
the sale or refinancing of the underlying real estate, which results in a cash
payment to the Partnership or a cash payment made to the Partnership from
surplus cash relative to the participation feature.

Results of Operations

The Partnership's net income decreased in the first quarter of 2004 as compared
to the first quarter of 2003 primarily due to decreases in MBS interest income
and other interest income and an increase in expense reimbursements to
affiliates. This decrease was partially offset by decreases in asset management
fees and general and administrative expenses. MBS interest income decreased
primarily due to the Signature Point payoff in 2003 and principal collections on
the single family MBS. Other interest income decreased primarily due to interest
received in the first quarter of 2003 from the Partnership's distribution
account. Expense reimbursements to affiliates increased primarily due to a
change in the cost of services associated with the wind-down of the
Partnership's activities and anticipated liquidation of the Partnership's assets
due to the expected refinancing of the Harbor Club PIM. Asset management fees
decreased due to the decrease in the Partnership's investments as a result of
principal collection and payoffs. General and administrative expense was greater
in the first quarter of 2003 primarily due to additional printing costs relating
to the SEC filing and legal costs associated with the Berkshire Income Realty,
Inc exchange offer.

Off Balance Sheet Arrangements

The Partnership has no off balance sheet arrangements as described in Item
303(a)(4)(ii) of Regulation S-K and did not have any such arrangements during
the period covered by this report on Form 10-Q.

Contractual Obligations

The Partnership has no contractual obligations as contemplated by Item 303(a)(5)
of Regulation S-K and did not have any such arrangements either during the
period covered by this report on Form 10-Q or during the Partnership's most
recent completed fiscal year.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Assessment of Credit Risk

The Partnership's investments in its MBS portion of PIM and its MBS are
guaranteed and/or insured by the Government National Mortgage Association
("GNMA"), Fannie Mae or the Federal Home Loan Mortgage Corporation ("FHLMC") 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. These
obligations are not guaranteed


                                      -8-


by the U.S. Government or the Federal Home Loan Bank Board. However, Fannie Mae
and FHLMC are two of the largest corporations in the United States with
significant experience in mortgage securitizations. In addition, their MBS carry
the highest credit rating given to financial instruments. GNMA guarantees the
full and timely payment of principal and basic interest on the securities it
issues, which represents interest 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.

At March 31, 2004, the Partnership includes in cash and cash equivalents
approximately $1.1 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 March
31, 2004, the Partnership's remaining PIM and MBS comprise the majority of the
Partnership's assets. Decreases in interest rates may accelerate the prepayment
of the Partnership's investments. Increases in interest rates may decrease the
proceeds from a sale of the MBS. The Partnership does not utilize any
derivatives or other instruments to manage this risk as the Partnership plans to
hold its remaining PIM investment to expected maturity. It is expected that
substantially all of the MBS will prepay over the same period, mitigating any
potential interest rate risk to the disposition value of any remaining MBS.

The Partnership monitors prepayments and considers prepayment trends, as well as
distribution requirements of the Partnership, when setting regular distribution
policy. For MBS, the Partnership forecasts prepayments based on trends in
similar securities as reported by statistical reporting entities such as
Bloomberg. For its remaining PIM, the Partnership incorporates prepayment
assumptions into planning as the property notifies the Partnership of the intent
to prepay or as it matures.

Item 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

As of March 31, 2004, the Senior Vice President and the Chief Accounting Officer
of Krupp Plus Corporation, a general partner of the Partnership, carried out an
evaluation of the effectiveness of the design and operation of the Partnership's
disclosure controls and procedures. The Senior Vice President and the Chief
Accounting Officer concluded that the Partnership's disclosure controls and
procedures were effective, as of the date of their evaluation, in timely
alerting them to material information relating to the Partnership required to be
included in this Quarterly Report on Form 10-Q.

(b) Changes in Internal Controls

There were no significant changes in the Partnership's internal controls or in
other factors that could significantly affect such internal controls subsequent
to the date of the evaluation described in paragraph (a) above.
