       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 on October 31, 1986.

The  Partnership's interests in Taxter Park
Associates ("Associates")  and  DWR
Chesterbrook  Associates,  the partnership
which  owned an interest  in  Chesterbrook
Corporate  Center (sold April 1998), are
accounted  for on the equity method.

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

Net  income per Unit amounts are calculated
by dividing net 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  the  sale of the Chesterbrook property
included  in equity  in  earnings of joint
ventures  in  the  second quarter  of
1998,  such adjustments  consist  only  of
normal recurring accruals.

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, 1998.  Operating results of
interim periods may not  be indicative  of
the operating results  for  the  entire
year.

       Notes to Financial Statements
2. Investments in Joint Ventures
During  the  third  quarter of  1999,  the
Partnership received  $95,000,  its share
of  the  balance  of  the escrow   deposit
(plus  interest)  returned                     to   DWR
Chesterbrook   Associates   by   the
buyer     of the
Chesterbrook  property.  The  joint
venture  did not
include  the  amount of the sale proceeds
deposited  in escrow  in its calculation of
the gain on the  sale  of the  property
allocated to the Partnership  because  of
the  uncertainty of the recoverability  of
the  escrow deposit.   As a result, the
Partnership recognized  the amount of the
third quarter cash receipt as an increase
to  its  share of the gain on the sale of
the property, and recorded such gain, along
with $51,000 received  in settlement of
various property operating matters, as  a
component of its equity in earnings of
joint ventures.

In  1987,  Associates   sold a  leasehold
interest  in approximately 20% of the space
at Taxter Corporate Park to KLM.  In 1998,
KLM accepted a $6.75 million purchase offer
for the leasehold interest,
which  Associates had the right to match.
The partners of  Associates believe that
inclusion of the KLM  space improves  the
value and salability  of  the  property;
however, the partners did not have
sufficient  cash  to fund  the  purchase.
Therefore, an  affiliate  of  the Managing
General  Partner  (the  "Affiliate"),  as
an accommodation,  purchased  the
leasehold  interest  on February  8,  1999
for $6.75 million  and  assumed  the rights
and obligations of KLM thereunder.

On February 4, 1999, Associates and KLM
entered into  a new lease which allows KLM
to continue to occupy 50% of the  space
subject  to  the  leasehold  interest.              On
February 8, 1999, the Affiliate also
assumed the rights and obligations of
Associates under this new lease. <PAGE>
<TABLE>
 DEAN WITTER REALTY INCOME PARTNERSHIP IV,
                   L.P.

       Notes to Financial Statements

As  part  of  the  purchase of the
leasehold  interest, Associates received an
option to purchase the leasehold interest
and  assume the new lease from the
Affiliate for a purchase price of $6.75
million plus the cost  of any   tenant
improvements,  leasing  commissions            and
capital  expenditures incurred  by  the
Affiliate    in
connection  with the leasehold interest
(collectively, the  "Resale  Price").
Associates  also  granted  the Affiliate
an option to require Associates to
purchase the leasehold interest and assume
the new lease for the Resale  Price.   When
the property is sold,  Associates will  be
obligated to purchase the leasehold
interest and assume the new lease from the
Affiliate for the new Resale Price.

Summarized  financial information of
Associates  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.
Effective January 1, 1999, the  affiliate
reduced  its  fees for these services
because  of  the greatly  decreased level
of partnership  activity.  For the  nine-
month periods ended September  30,  1999
and 1998,  the  Partnership incurred
approximately  $56,000 and  $154,000  for
these services, respectively.  These
amounts  are  included  in general  and
administrative expenses.

 DEAN WITTER REALTY INCOME PARTNERSHIP IV,
                   L.P.

       Notes to Financial Statements


In  1998,  another  affiliate of the
Managing  General Partner  provided
property  management  services   for
Taxter  Corporate  Park  and  five
buildings  at         the
Chesterbrook Corporate Center (until the
buildings were sold   in  April  1998).
The  Partnership  paid           the
affiliate  management fees of approximately
$62,000  in 1998.   These  fees were
recorded as  expenses  of  the joint
ventures.  In 1999, property management
services for   Taxter   Corporate  Park
are  provided         by   an
unaffiliated party.

                   L.P.

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

Liquidity and Capital Resources

The   Partnership  raised  $152,218,500  in
a   public offering of 304,437 units which
was terminated in 1988. The  Partnership
has  no  plans  to  raise  additional
capital.

The  Partnership's interest in the Taxter
property  is the   Partnership's   sole
property   interest.                         The
partnership  which  owns  the  Taxter
Corporate   Park property (the "Taxter
Partnership") has accepted a  bid from  an
unaffiliated  third  party  to  purchase
the property, and the parties are currently
negotiating the terms  of a purchase and
sale agreement. However, there can  be  no
assurance that the Taxter property will  be
sold.

On  February  8,  1999, an affiliate  of
the  Managing General  Partner,  as an
accommodation  to  the  Taxter Partnership,
purchased the leasehold interest of KLM in
approximately 20% of the property's space.
See Note  2 to the financial statements.

Currently,  the overall vacancy levels  in
the  office market  in  Westchester County,
New York and  the  west Westchester  sub-
market in which Taxter Corporate  Park is
located are approximately 18% and 14%,
respectively. During  the  three  months
ended  September  30,  1999, occupancy  at
the property decreased from 76%  to  72%.
Leases  aggregating approximately 39% of
the property's space expire in 2001.

During  the nine months ended September 30,
1999,  the Taxter  property  generated
positive  cash  flow  from operations, and
it is anticipated that it will continue to
do so during the period the Partnership
continues to own its interest in the
property.


<PAGE>
 DEAN WITTER REALTY INCOME PARTNERSHIP IV,
                   L.P.

The  Taxter  Partnership expects to buy the
former  KLM leasehold  interest at the time
that  the  property  is sold, using a
portion of the proceeds from the sale  of
the  Taxter  property.  As of September 30,
1999,  the Partnership   had  commitments
to  fund  approximately $84,000  for  its
share  of  tenant  improvements  and
leasing commissions at the Taxter property.

During  the  nine-months  ended  September
30,   1999, distributions   received  from
the  Taxter  Partnership exceeded  cash
used in operations and contributions  to
the Taxter Partnership.

The  Partnership  did not pay any
distributions  during the  nine  months
ended September 30, 1999.  Generally,
future  cash  distributions will be paid
from  proceeds
received  from  the  sale of the Taxter
property,  the final  Chesterbrook sale
proceeds (see note  2  to  the financial
statements) and cash reserves.
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 nine-month
periods ended September  30, 1999 compared
to 1998 are primarily attributable to the
following:
Equity  in  earnings of joint ventures and
general  and administrative expenses
decreased in 1999  compared  to 1998
primarily  due  to the sale of  the
Chesterbrook Corporate Center in April
1998.
During   the   three-  and  nine-month
periods   ended September  30,  1999, the
Partnership's equity  in  the earnings  of
the Taxter Partnership was  approximately
$29,000  and  $262,000 respectively.
During  the  same periods  in  1998,  the
Partnership's  equity  in  the earnings of
the  Taxter  partnership  was approximately
$366,000  and $593,000,
<PAGE>
 DEAN WITTER REALTY INCOME PARTNERSHIP IV,
                   L.P.

respectively. In the third quarter of 1998,
the  Taxter Partnership  received  a refund
of  prior  years  real estate taxes of
approximately
$530,000   (the  Partnership's  share  of
which                                               was
approximately $217,000).  Also, the
Partnership's share of 1999 bad debt
expense was approximately $100,000 and
$171,000  during  the three and nine month
periods  in 1999,  respectively;  there
were no bad  debt  expenses for the
comparable periods in 1998.

During   the  nine  months  ended
September   30,1999, interest  and other
revenues decreased due to  interest earned
in  1998 on the proceeds from the sale  of
the Chesterbrook   property  before  such
proceeds   were distributed to the Limited
Partners.

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

Year 2000 Readiness

Many  of the world's computer systems
(including  those in  non-information
technology equipment  and  systems)
currently record years in a two-digit
format.   If  not addressed,  such
computer systems  may  be  unable  to
properly  interpret dates beyond the year
1999,  which could  lead  to business
disruptions in  the  U.S.  and
internationally (the "Year 2000" issue).
The potential costs  and uncertainties
associated with the Year  2000 issue  may
depend  on a number of  factors,  including
software,  hardware and the nature of the
industry  in which a company operates.
Additionally, companies must coordinate
with  other  entities  with   which   they
electronically  interact.  The  Partnership
and the
Managing  General Partner recognize the
importance  of insuring that its business
operations are not disrupted as  a  result
of the Year 2000 issue and have  taken  a
number  of  steps to insure that Year 2000
issues  are identified and remediated.
The  Managing General Partner has assessed
its internal computer  information systems
and is  taking  steps  to remediate  its
mission-critical systems (at no cost  to
the  Partnership). The Managing General
Partner is also surveying  and
communicating with  vendors  (primarily
property managers and banks) with whom it
has important financial  and operating
relationships,   to  determine the  extent
to which they are vulnerable to  Year  2000
issues, in order either to insure
compliance or develop contingency plans to
mitigate the risk associated  with a non-
compliant vendor.  This process is expected
to be completed during the fourth quarter
of 1999.
In  addition,  the Managing General Partner
and  these vendors  are  currently
evaluating   and    assessing those
mission-critical   computer  systems   in           the
Partnership's  properties not  related  to
information technology.  These systems,
which generally operate  in a     building
include,     without     limitation,
telecommunication, security (such as  card-
access  door lock systems), energy
management  and elevator systems. As  a
result  of the technology used in this
type  of equipment, it is possible that
this equipment  may  not be  repairable
and  accordingly may  require  complete
replacement   by   the   Partnership.
Because                                            this
assessment  is ongoing, the total cost of
bringing  all systems and equipment into
Year 2000 compliance has not been    fully
quantified.    Based   upon   available
information, the General Partner does not
believe  that these costs will have a
material adverse effect on  the
Partnership's business, financial condition
or results. However,  it  is possible that
there could  be  adverse consequences  to
the Partnership as a  result  of  Year 2000
issues that are outside the Partnership's
control. The  General  Partner is
evaluating  these  issues  and developing
contingency plans where appropriate.

There  are  many risks associated with  the
Year  2000 issue,  including  the
possibility  of  a  failure  of computer
and non-information technology systems.            Such
failures could cause system malfunctions
which may have a  material  adverse effect
on the Partnership  or  its properties.  In
addition, even if the General  Partner
successfully  remediates  its  Year  2000
issues,  the Partnership can be materially
and adversely affected by failures  of
third parties to remediate their own  Year
2000   issues.    The   Partnership
recognizes                                          the
uncertainty of such external dependencies
since it  can not  directly control the
remediation efforts of  third parties.
The failure of third parties with which
the Partnership  has financial or
operational relationships such as

banks,   tenants,   vendors,  property
managers                                            and
utilities,  to  remediate  their  computer
and                                                non-
information  technology  systems  issues
in  a  timely manner could result in a
material financial risk to the Partnership.

If  the  above  mentioned risks are not
remedied,  the Partnership  may  experience
business  interruption  or shutdown,
financial loss, or regulatory actions.

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 or its properties.
