1. General

      The accompanying financial statements, footnotes and discussions should be
      read in conjunction with the financial statements, related footnotes and
      discussions contained in the Partnership's Annual Report on Form 10-KSB

      The financial information contained herein is unaudited. In the opinion of
      management, all adjustments necessary for a fair presentation of such
      financial information have been included. All adjustments are of a normal
      recurring nature. The balance sheet at December 31, 2004 was derived from

      and 2004 are not necessarily indicative of the results to be expected for

Item 2. Management's Discussion and Analysis or Plan of Operation

      The matters discussed in this Form 10-QSB contain certain forward-looking
      statements and involve risks and uncertainties (including changing market
      conditions, competitive and regulatory matters, etc.) detailed in the
      disclosure contained in this Form 10-QSB and the other filings with the
      Securities and Exchange Commission made by the Partnership from time to
      time. The discussion of the Partnership's liquidity, capital resources and
      results of operations, including forward-looking statements pertaining to
      such matters, does not take into account the effects of any changes to the
      Partnership's operations. Accordingly, 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.

      This Item should be read in conjunction with the financial statements and
      other items contained elsewhere in the report.

      Liquidity and Capital Resources

      As of June 30, 2005, the Partnership retained an equity interest in three
      Local Limited Partnerships, each of which owns one apartment complex. One
      property is located in Michigan and two properties are located in North
      Carolina.

      The level of liquidity based on cash and cash equivalents experienced a
      $67,000 decrease for the six months ended June 30, 2005 as compared to
      December 31, 2004, as a result of $67,000 of cash used in operating
      activities. At June 30, 2005, the Partnership had $301,000 in cash and
      cash equivalents, which have been invested primarily in repurchase
      agreements and a money market account.

      The Partnership's primary source of income is distributions from the Local
      Limited Partnerships. The Partnership requires cash to pay general and
      administrative expenses and to make capital contributions to any of the
      Local Limited Partnerships, which the managing general partner deems to be
      in the Partnership's best interest to preserve its ownership interest. To
      date, all cash requirements have been satisfied by interest income, cash
      distributed by the Local Limited Partnerships to the Partnership or by
      loans.

      The Partnership does not intend to make advances to fund future operating
      deficits incurred by any Local Limited Partnership, but retains its
      prerogative to exercise business judgment to reverse this position if
      circumstances change. Moreover, the Partnership is not obligated to
      provide any additional funds to the Local Limited Partnerships to fund
      operating deficits. If a Local Limited Partnership sustains continuing
      operating deficits and has no other sources of funding, it is likely that
      it will eventually default on its mortgage obligations and risk a
      foreclosure on its property by the lender. If a foreclosure were to occur,
      the Local Limited Partnership would lose its investment in the property
      and would incur a tax liability due to the recapture of tax benefits taken
      in prior years. The Partnership, as an owner of the Local Limited
      Partnership, would share these consequences in proportion to its ownership
      interest in the Local Limited Partnership.

            WINTHROP RESIDENTIAL ASSOCIATES I, A LIMITED PARTNERSHIP
                            FORM 10-QSB June 30, 2005

      Liquidity and Capital Resources (continued)

      The Partnership has been advised that the Local Limited Partnership that
      holds Stonegate Apartments, located in Michigan, entered into a purchase
      agreement on April 11, 2005 for a purchase price of approximately
      $4,420,000. However, on April 28, 2005, the purchaser exercised the right
      to terminate the purchase agreement under the provisions of the agreement.
      The Local Limited Partnership is continuing to market the property for
      sale and has received a reduced offer from another third party to purchase
      the property for less than the mortgage balance, which would require
      lender concessions to be consummated. Any other new proposal is expected
      to be below the current outstanding mortgage balance of approximately
      $4,200,000. There can be no assurance that a new purchase agreement will
      be entered into or that the property will ultimately be sold. The property
      is in need of significant rehabilitation and is experiencing operating
      deficits and high vacancy rates. An estimated $800,000 is needed to make
      repairs to the property. It is unlikely that a purchase price in excess of
      the mortgage debt will be obtained. Accordingly, if the lender is
      unwilling to accept a discounted pay-off amount, it is likely that the
      property would be foreclosed upon. Accordingly, it is presently expected
      that the Partnership will not receive any distributions from this Local
      Limited Partnership in the foreseeable future.

      None of the recently issued accounting standards had any effect on the
      Partnership's financial statements.

      Results of Operations

      The Partnership's net loss was $60,000 for the six months ended June 30,
      2005, as compared to a net loss $43,000 for the comparable period in 2004.
      The increase was the result of an increase in various general and
      administrative expenses of $16,000 and a decrease in interest income of
      $1,000.

      Quantitative and Qualitative Disclosures of Market Risk

      The Partnership does not have any financial instruments that would expose
      it to market risk associated with the risk of loss arising from adverse
      changes in market rates and prices.

Item 3.Controls and Procedures

      The Partnership's management, with the participation of the Partnership's
      Chief Executive Officer and Chief Financial Officer, has evaluated the
      effectiveness of the Partnership's disclosure controls and procedures (as
      such term is defined in Rule 13a-15(e) under the Securities Exchange Act
