                          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 has effectuated the dissolution of the
Partnership. However, the Partnership can't 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 in 2001.

The Partnership's interest in TPA was 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) income per Unit amounts are calculated by dividing net (loss) income
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 necessary to present fairly the
results for the interim period. Except for the gain on sale of the Taxter
property included in the equity in earnings of joint venture amounts in 2000,
such adjustments consist only of normal recurring accruals.

These financial statements should be read 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, 2000. Operating results of interim periods may not be
indicative of the operating results for the entire year.

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

The Partnership understands that TPA has certain operating issues that TPA must
resolve, both with the buyer of the Taxter property and other third parties,
before TPA can terminate its operations. Resolution of these issues is not
anticipated to require any significant funding from the Partnership.

Summarized financial information of TPA is as follows:

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, 2001 and 2000, the
Partnership incurred approximately $20,000 and $36,000 for these services,
respectively. These amounts are included in general and administrative expenses.

4.   Distributions
     -------------

On February 27, 2001, the Partnership distributed, 100% to Limited Partners,
approximately $913,000 ($3.00 per Unit). This distribution consisted of $406,000
($1.33 per Unit) of the remaining undistributed proceeds from the sale of the
Taxter property and $507,000 ($1.67 per Unit) of Partnership cash reserves. The
General Partners deferred receipt of their share of the cash reserves
distribution (approximately $56,000) to ensure that the Partnership would have
cash on hand to cover all liabilities that may arise while the Partnership winds
up its affairs. The amounts deferred were charged against Partner's capital and
recorded as distributions payable.

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


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

As discussed in Note 1 to the 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 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 in 2001.

As discussed in Note 4 to the Financial Statements, on February 27, 2001, the
Partnership paid, to Limited Partners only, a distribution of $3.00 per Unit.
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, 2001 compared to 2000 are primarily attributable to the
following:

The absence of the Partnership's equity in earnings of joint venture in 2001 is
due to the loss of operating income from TPA after it sold the Taxter property
in May 2000. The Partnership's share of the gain on sale of the Taxter property
(approximately $5.0 million) was included in the equity in earnings of joint
venture amounts in 2000.
<PAGE>

                 DEAN WITTER REALTY INCOME PARTNERSHIP IV, L.P.


The decreases in interest and other revenues in 2001 compared to 2000 are
primarily due to the absence in 2001 of a first quarter 2000 receipt of $28,000
in settlement of litigation with the original building contractor and architect
of the Pasadena Financial Center property (sold 1997) and the second quarter
2000 interest earned on the Taxter sale proceeds until such proceeds were
distributed to Limited Partners.

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
