                          Notes to Financial Statements

                   Three months ended March 31, 2000 and 1999
                                   (Unaudited)

(1)  Basis of Presentation
--------------------------

     The accompanying interim financial statements have been prepared in
         accordance with generally accepted accounting principles and, in the
         opinion of management, contain all necessary adjustments for a fair
         presentation. The Partnership's significant accounting policies are set
         forth in its December 31, 1999 Form 10-K. The interim financial
         statements should be read in conjunction with the financial statements
         included therein. The interim results should not be considered
         indicative of the annual results. Certain reclassifications of prior
         period numbers may have been made to conform to the current period
         presentation.

(2)  Organization
-----------------

     Realmark Property Investors Limited Partnership - IV (the Partnership),
         a Delaware limited partnership, was formed on February 12, 1985, to
         invest in a diversified portfolio of income producing real estate
         investments. The general partners are Realmark Properties, Inc. (the
         corporate general partner) and Joseph M. Jayson (the individual general
         partner). Joseph M. Jayson is the sole stockholder of J.M. Jayson &
         Company Inc. Realmark Properties, Inc. is a wholly-owned subsidiary of
         J.M. Jayson & Company, Inc. Under the partnership agreement, the
         general partners and their affiliates can receive compensation for
         services rendered and reimbursement for expenses incurred on behalf of
         the Partnership.

(3)  Property and Equipment
---------------------------

     In 1998, a plan was established to dispose of the Partnership's only
         property, Andover Park. Management has determined that a sale of the
         property is in the best interest of the limited partners and continues
         to actively market the property for sale. Therefore, the assets are
         carried at the lower of depreciated cost or fair value less costs to
         sell and are not depreciated during the disposal period. Depreciation
         expense not recorded for the three months ended March 31, 2000 and 1999
         was approximately $44,000 in both periods.

(4)  Going Concern Considerations
---------------------------------

     The accompanying financial statements have been prepared assuming that the
         Partnership will continue as a going concern. The Partnership has
         sustained recurring losses from operations and has experienced
         operating cash flow difficulties. These factors, combined with
         significant partners' deficits, raise substantial doubt about the
         Partnership's ability to continue as a going concern.

     Management is continuing its efforts to improve operating results by
         closely monitoring expenditures, increasing rents, decreasing vacancies
         and improving collections. Management has committed to a plan to sell
         the Partnership's remaining property, Andover Park. Marketing efforts
         to sell this property will include advertising in national newspapers,
         mailing of sales packages to brokers and follow-up telephone calls to
         brokers. The financial statements do not include any adjustments that
         might result from the outcome of this uncertainty.

(5)  Sale of Property
---------------------

     In August 1999, the Partnership sold Woodbridge Manor at a gain for
         financial statement purposes of $1,131,370. This property had revenues
         of $249,059 and expenses of $310,840 during the three months ended
         March 31, 1999.

(6)  Current Accounting Pronouncements
--------------------------------------

     In  June 2000, the Financial Accounting Standards Board issued Statement of
         Financial Accounting Standards No. 138 - "Accounting for Certain
         Derivative Instruments and Certain Hedging Activities, an Amendment of
         Statement No. 133" which amends certain provisions of Statement of
         Financial Accounting Standards No. 133 - "Accounting for Derivative
         Instruments and Hedging Activities." These statements establish
         accounting and financial reporting standards for derivative instruments
         and hedging activities. These statements become effective for the
         Partnership on January 1, 2001. The effect, if any, that Statements No.
         133 and 138 will have on the Partnership's operations and financial
         position will not be material.

(7)  Subsequent Event - Contingency
-----------------------------------

     The Partnership, as a nominal defendant, the General Partners of the
         Partnership and the three individuals constituting the officers and
         directors of the Corporate General Partner, as defendants, were served
         with a Summons and Complaint on April 19, 2000 in a class and
         derivative action instituted by Ira Gaines and on August 21, 2000 in a
         class and derivative action instituted by Sean O'Reilly and Louise
         Homburger, each in Supreme Court, County of Erie, State of New York.
         The actions allege breaches of contract and breaches of fiduciary duty
         and seek, among other things, an accounting, the removal of the General
         Partners, the liquidation of the Partnership and the appointment of a
         receiver to supervise the liquidation, and damages. The General
         Partners and the officers and directors of the Corporate General
         Partner have filed a motion to dismiss the first complaint and are
         presently reviewing the second complaint and intend to vigorously
         pursue their defense.

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


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

The Partnership continues to incur operating cash flow deficits and losses. Due
to the operating shortfalls, the Partnership did not make any distributions in
the quarters ended March 31, 2000 and 1999. Until such time as the Partnership
can satisfy its obligations and repay the Corporate General Partner and
affiliate advances, which is not expected to happen prior to the sale of the
remaining property in the Partnership, no distributions are anticipated.

During 1999, Woodbridge Manor Apartments, located in Lansing, Michigan was sold
for a sale price of $6,400,000. The sale resulted in a $1,131,370 total gain for
financial statement purposes for the year ended December 31, 1999. In the first
quarter of 2000, a portion of the sale proceeds was used to reduce the
Partnership's liability to affiliated parties.

Management continues its corrective action plan in response to the going concern
considerations discussed in the notes to the financial statements. More
attention has been centered on increasing revenues.


Results of Operations
---------------------

To properly compare the first quarters of 1999 and 2000, the 1999 numbers must
be reduced by Woodbridge Manor's results. The 1999 operating statement amounts
so adjusted and compared to the 2000 amounts are summarized as follows (in
thousands):

                                                         1999             2000
                                                         ----             ----

         Rental income                                   $211              255
         Other income                                      17               34
         Expenses:
            Property operations                           135              157
            Interest                                      159              160
            Administrative                                122               61

         Net loss                                        (188)             (89)

This comparison shows an improvement in operations that primarily reflects those
of the Partnership's remaining property, Andover Park. Reduced vacancies and
improved collections led to the $44,000 increase in rental income. The increase
in other income is interest. More than half of the increase in property
operating expense was generated by repairs and maintenance, with the remainder
attributable to a variety of relatively small items. The $61,000 decrease in
administrative expense is the result of lower professional and portfolio
management fees.

<PAGE>
PART I - Item 3.     Quantitative and Qualitative Disclosures About Market Risk
                     ----------------------------------------------------------

       The Partnership's cash equivalents are short-term, interest-bearing bank
           accounts and its mortgage loans are fixed-rate. It has not entered
           into any derivative contracts. Therefore, it has no market risk
           exposure.


                           PART II - OTHER INFORMATION
                           ---------------------------

      The Partnership, as a nominal defendant, the General Partners of the
          Partnership and the three individuals constituting the officers and

          General Partners, the liquidation of the Partnership and the
          appointment of a receiver to supervise the liquidation, and damages.
