                          Notes to Financial Statements

                  Nine months ended September 30, 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)  Disposition of Rental Property
-----------------------------------

     During the first three months of 2000 (through March 31, 2000), management
         continued its plan, originated in 1998, to sell the assets of the
         Partnership's only property, Andover Park. Effective April 1, 2000,
         management discontinued the plan. The assets are carried at the lower
         of depreciated cost or fair value less costs to sell and were not
         depreciated during the disposal period. Depreciation expense not
         recorded for the nine months ended September 30, 2000 and 1999 was
         approximately $44,000 and $132,000, respectively and $44,000 for the
         three months ended September 30, 1999.

      In August 1999, the Partnership sold Woodbridge Manor at a gain for
         financial statement purposes of $1,131,370. This property had revenues
         of $684,153 and expenses of $954,833 during the nine months ended
         September 30, 1999.

(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 operations results by
         closely monitoring expenditures, increasing rents, decreasing vacancies
         and improving collections. The financial statements do not include any
         adjustments that might result from the outcome of this uncertainty.

(6)  Prior Period Adjustments
-----------------------------

     Net income for the three and nine month periods ended September 30, 1999
         has been corrected to give effect to year-end 1999 adjustments as
         follows:

(7)  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.


(8)  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 nine months ended September 30, 2000 and 1999. Until such time as the
Partnership can satisfy its obligations and repay the amounts due to affiliates,
which is not expected to happen prior to the sale of the remaining property in
the Partnership, no distributions are anticipated.

In August 1999, Woodbridge Manor Apartments, located in Lansing, Michigan was
sold for $6,400,000, resulting in a $1,131,370 gain for financial statement
purposes. 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
---------------------

As previously indicated, the Woodbridge Manor property was sold in August 1999
and, therefore, its results of operations are included in the Partnership's
financial statements only through the sale date. Accordingly, the significant
decreases in expenses (excluding depreciation) in both the three month and the
nine month periods ended September 30, 2000, as compared to the 1999 comparable
periods, are primarily attributable to the absence of Woodbridge Manor in the
2000 results.

The Partnership's remaining property, Andover Park apartments, while sustaining
a less than 5% decrease in income in the third quarter, experienced an increase
in income of approximately $35,000 for the nine month period. Its expenses
showed little change in the 2000 periods except for repairs, maintenance and
replacements. The cost of those items decreased significantly in 2000 since
there was a major effort in 1999 to improve the property. Nonetheless, the
property continues to show negative cash flow. The General Partner intends to
reinstitute the plan to sell the property in the near future.

                    ----------------------------------------------------------

     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.

Item 1.  Legal Proceedings
--------------------------

     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.
