                          Notes to Financial Statements

1.   The Partnership
     ---------------

Dean Witter Realty Income Partnership IV, L.P. (the "Partnership") is a limited
partnership organized under the laws of the State of Delaware in 1986.

The Partnership's last remaining property investment was its 40.6% interest in
the partnership ("TPA") which owned Taxter Corporate Park. TPA sold the Taxter
property on May 23, 2000, and this sale effectuated the dissolution of the
Partnership. However, the Partnership will not be able to wind up its affairs,
and distribute the balance of the Partnership's cash reserves until TPA
terminates its operations (see Note 2). The Managing General Partner plans to
terminate the Partnership as soon as possible.

The Partnership's 40.6% interest in TPA is accounted for using the equity
method.

The Partnership's records are maintained on the accrual basis of accounting for
financial and tax reporting purposes.

Net loss per Unit amounts are calculated by dividing net loss allocated to
Limited Partners, in accordance with the Partnership Agreement, by the weighted
average number of Units outstanding.

In the opinion of management, the accompanying financial statements, which have
not been audited, include all adjustments, consisting only of normal recurring
accruals, necessary to present fairly the results for the interim period.

These financial statements should be read in conjunction with the annual
financial statements and notes thereto included in the Partnership's annual
report on Form 10-K filed with the Securities and Exchange Commission for the
year ended December 31, 2001. Operating results of interim periods may not be
indicative of the operating results for the entire year.

                          Notes to Financial Statements

2.   Investment in Joint Venture
     ---------------------------

TPA appealed the amount of real estate taxes it was charged by the local taxing
authorities during the 1997 to 2000 tax years. TPA won a judgment in the Trial
Court from which the Partnership would receive approximately $300,000. However,
the taxing authorities have appealed the judgment, and TPA has entered into
settlement discussions with the taxing authorities. Accordingly, the amount that
the Partnership ultimately collects from TPA's real estate tax appeal may be
substantially less than the Partnership's share of the judgement. The
Partnership understands that TPA must resolve this appeal before TPA can
terminate its operations. Resolution of these issues is not anticipated to
require any significant funding from the Partnership.

3.   Related Party Transactions
     --------------------------

An affiliate of the Managing General Partner performs administrative functions,
processes investor transactions and prepares tax information for the
Partnership. For the six-month periods ended June 30, 2002 and 2001, the
Partnership incurred approximately $13,000 and $20,000, for these services,
respectively. These amounts are included in general and administrative expenses.

At June 30, 2002, the Partnership's accounts payable and accrued liabilities
included approximately $35,000 due to the affiliate. This amount consisted of
the above-mentioned $13,000 due to the affiliate and a $22,000 payable for the
reimbursement of expenses the affiliate paid on behalf of the Partnership during
2002.

Item 2.    Management's Discussion and Analysis of Financial
           -------------------------------------------------
           Condition and Results of Operations
           -----------------------------------

Liquidity and Capital Resources
-------------------------------

As discussed in Note 1 to financial statements, the partnership ("TPA") which
owned the Taxter office property sold the property on May 23, 2000. The
Partnership's interest in TPA was the Partnership's only remaining property
interest. The Partnership dissolved pursuant to the terms of its Partnership
Agreement, effective May 23, 2000, the date on which the Taxter property was
sold. The Partnership owned its 40.6% interest in the Taxter property through
TPA, and the Partnership will not be able to wind up its affairs and distribute
the balance of the Partnership's cash reserves until TPA terminates its
operations (see Note 2 to the financial statements). The Partnership plans to
wind up its affairs, distribute its remaining cash reserves and terminate its
existence by filing a certificate of cancellation in the office of the Delaware
Secretary of State as soon as possible. The Partnership believes that its
remaining cash reserves are adequate for its needs until the Partnership is
terminated.

Except as discussed above and in the financial statements, the Managing General
Partner is not aware of any trends or events, commitments or uncertainties that
may have a material impact on liquidity.

Operations
----------

Fluctuations in the Partnership's operating results for the three and six month
periods ended June 30, 2002 compared to 2001 are primarily attributable to the
following:

The equity in earnings of joint venture recognized in the 2002 periods represent
the Partnership's share of Taxter tenant receivables, collected by TPA during
the second quarter of 2002, which had been previously written off.
<PAGE>

                 DEAN WITTER REALTY INCOME PARTNERSHIP IV, L.P.


Interest and other revenues decreased in the 2002 periods compared to 2001
primarily due to a decrease in interest rates and a decline in average cash held
by the Partnership (in February 2001, the Partnership distributed over $910,000
to the Limited Partners).

General and administrative expenses decreased in the 2002 periods compared to
2001 primarily due to expense reductions and the decreased level of Partnership
activities as the Partnership winds up its affairs.

There were no other individually significant factors which caused changes in
revenues or expenses.

Inflation
---------

Inflation has been consistently low during the periods presented in the
financial statements and, as a result, has not had a significant effect on the
operations of the Partnership.

Item 3.     Quantitative and Qualitative Disclosure About
            ---------------------------------------------
            Market Risk
            -----------

Market risk refers to the risk that a change in the level of one or more market
prices, rates, indices, volatilities, correlations or other market factors, such
as liquidity, will result in losses for a position or portfolio.

Other than the Partnership's interest in TPA, the Partnership's assets consist
of cash and short-term time deposits. The Partnership does not hold any
instruments for trading purposes. The Partnership's liabilities consist of
accounts payable and other short-term liabilities. At June 30, 2002 the
Partnership had no material exposure to market risk. It also does not hold any
