                          NOTES TO FINANCIAL STATEMENTS
                          -----------------------------
                  Nine Months Ended September 30, 1998 and 1997
                  ---------------------------------------------
                                   (Unaudited)

1.   GENERAL PARTNERS' DISCLOSURE
     ----------------------------

     In the opinion of the General Partners of Realmark Property Investors
     Limited Partnership IV, all adjustments necessary for a fair presentation
     of the Partnership's financial position, results of operations and changes
     in cash flows for the nine month periods ended September 30, 1998 and 1997,
     have been made in the financial statements. Such financial statements are
     unaudited and subject to any year-end adjustments which may be necessary.

2.   FORMATION AND OPERATION OF PARTNERSHIP
     --------------------------------------

     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.

     In April 1985, the Partnership commenced the public offering of units of
     limited partnership interest. Other than matters relating to organization,
     it had no business activities and, accordingly, had not incurred any
     expenses or earned any income until the first interim closing (minimum
     closing) of the offering, which occurred on September 20, 1985. On June 22,
     1986 the offering was concluded, at which time 23,362.9 units of limited
     partnership interest were outstanding, excluding 3 units held by an
     affiliate of the General Partners. The General Partners are Realmark
     Properties, Inc., a wholly-owned subsidiary of J.M. Jayson & Company, Inc.
     and Joseph M. Jayson, the Individual General Partner. Joseph M. Jayson is
     the sole shareholder 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.

     Net income or loss and proceeds arising from a sale or refinancing shall be
     distributed first to the limited partners in amounts equivalent to a 7%
     return on the average of their adjusted capital contributions, then an
     amount equal to their capital contributions, then an amount equal to an
     additional 5% of the average of their adjusted capital contributions after
     the general partners receive a disposition fee, then to all partners in an
     amount equal to their respective positive capital balances and, finally, in
     the ratio of 87% to the limited partners and 13% to the general partners.

                                       -8-


<PAGE>

     FORMATION AND OPERATION OF PARTNERSHIP  (CONTINUED)
     --------------------------------------------------

     The partnership agreement also provides that distribution of funds,
     revenues, costs and expenses arising from partnership activities, exclusive
     of any sale or refinancing activities, are to be allocated 97% to the
     limited partners and 3% to the general partners.

3.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     ------------------------------------------

     Use of estimates
     ----------------

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

     Cash
     ----

     For purposes of reporting cash flows, cash includes the following items:
     cash on hand; cash in checking; and money market savings.

     Property and Depreciation
     -------------------------

     Depreciation is provided using the straight-line method over the estimated
     useful lives of the respective assets. Expenditures for maintenance and
     repairs are expensed as incurred, and major renewals and betterments are
     capitalized. The Accelerated Cost Recovery System and Modified Accelerated
     Cost Recovery System are used to determine depreciation expense for tax
     purposes.

     Rental Income
     -------------

     Leases for residential properties have terms of one year or less.
     Commercial leases have terms of from one to five years. Rental income is
     recognized on the straight line method over the term of the lease.

     Minority Interest in Consolidated Joint Venture
     -----------------------------------------------

     The minority interest in a consolidated joint venture is stated at the
     amount of capital contributed by the minority investors adjusted for their
     share of joint venture losses.

4.   ACQUISITION AND DISPOSITION OF RENTAL PROPERTY
     ----------------------------------------------

     In November 1985, the Partnership acquired a 168 unit apartment complex
     (Lakeview Village) located in Milwaukee, Wisconsin, for a purchase price of
     $4,411,659, which included $320,779 in acquisition fees.

     In December 1985, the Partnership acquired a 288 unit apartment complex
     (Woodbridge Manor, formerly Sutton Park) located in Lansing, Michigan for a
     purchase price of $7,252,858, which included $588,716 in acquisition fees.

     In August 1986, the Partnership acquired two office/warehouse buildings
     consisting of 62,598 square feet (Airlane I) and 68,300 square feet
     (Airlane III), consisting of approximately 25% office space and 75%
     warehouse space located in Nashville, Tennessee, for a purchase price of
     $6,180,920, which included $383,169 in acquisition fees.

     In October 1986, the Partnership acquired an 86 unit apartment complex
     (Gold Key Village II) located in Englewood, Ohio for a purchase price of
     $2,354,615, which included $152,744 in acquisition fees.

     In December 1986, the Partnership acquired two apartment complexes
     consisting of 96 and 144 units (Creekside Apartments, formerly Bretton Park
     I and II) located in Flat Rock, Michigan, for a purchase price of
     $5,462,176, which included $445,964 in acquisition fees.

     In December 1986, the Partnership acquired a 215 unit apartment complex
     (Andover Park, formerly Willow Creek) located in Greenville, South
     Carolina, for a purchase price of $5,040,560, which included $477,987 in
     acquisition fees.

     In December 1986, the Partnership acquired a 72 unit apartment complex
     (Evergreen Terrace) located in Lansing, Michigan for a purchase price of
     $1,1711,093, which included $314,379 in acquisition fees.

     In May 1987, the Partnership acquired a 56 unit apartment complex (Cedar

     ACQUISITION AND DISPOSITION OF RENTAL PROPERTY  (CONTINUED)
     ----------------------------------------------------------

     In 1988, the Partnership acquired, upon its dissolution, the net assets and
     liabilities of the Willow Lake Joint Venture, which amounted to $1,635,474.
     Since the date of the acquisition, the Partnership had capitalized
     additional construction costs of $5,059,296 which included capitalized
     interest of $151,993. Construction on this project was substantially
     complete in early 1991. During September 1992, Willow Lake's lender
     foreclosed and took possession of the property because the Partnership had
     difficulty in obtaining tenant leases and financing to complete tenant
     build-out costs. The disposal generated a $1,328,352 loss for financial
     statement purposes.

     In October, 1989 the Partnership sold the Gold Key II apartment complex for
     $2,881,136 which generated a gain of $911,177 for financial statement
     purposes.

     In February 1998 Airlane Office Warehouse was sold for a sales price of
     $4,700,000. The sale resulted in a gain for financial statement purposes of
     $1,148,604.

     In March 1998 Creekside Apartments was sold for a sales price of
     $5,075,000. The sale generated a gain for financial statement purposes of
     $2,410,729.

     Financial Accounting Standards Statement No. 121, Accounting for the
     Impairment of Long-lived Assets and for Long-lived Assets to be Disposed Of
     (the "Statement") requires that assets to be disposed of be recorded at the
     lower of carrying value or fair value, less costs to sell. The Statement
     also requires that such assets not be depreciated during the disposal
     period, as the assets will be recovered through sale rather than through
     operations. In accordance with this Statement, the long-lived assets of the
     Partnership, classified as held for sale on the balance sheet, are recorded
     at the carrying amount which is the lower of carrying value or fair value
     less costs to sell, and have not been depreciated during the disposal
     period. Depreciation expense, not recorded during the disposal period, for
     the nine months ended September 30, 1997 totaled approximately $300,000.

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

     The Partnership has the following mortgages and notes payable:

     Lakeview
     --------

     In January 1996, the Partnership refinanced the mortgage. The refinanced

     early 1998.

     Woodbridge Manor (formerly Sutton Park)
     --------------------------------------

     The property was refinanced January 11, 1996 with an 8% mortgage for

     1997). The mortgage was payable monthly in amounts which vary with the
     interest rate. Monthly payments at June 30, 1997 based on 7.01% interest
     rate were $27,671.90. The balance of the mortgage was due and payable March

     Andover Park (formerly Willow Creek)
     -----------------------------------

     A mortgage with a balance of $3,948,450 at September 30, 1998. The mortgage
     has a two-year term with a variable interest rate set at a rate equivalent
     to 300 basis points over the thirty-day LIBOR rate (8.6875% at September
     30, 1998). The loan may at any time during the two years be converted to a
     thirty year fixed mortgage.

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

     An adjustable rate mortgage with a balance at September 30, 1998 and 1997
     of $1,009,005 and $1,011,763, respectively. The interest rate is adjustable
     annually to a maximum rate of 15% during the first five years of the loan
     term and 17% for the remaining life of the loan with a minimum rate of 9%.
     The mortgage is payable monthly in amounts which vary with the interest
     rate. The balance of the mortgage was due and payable May 24, 1998. As a
     result of the Partnership's failure to make regular principal and interest
     payments, the property was placed in receivership in October 1997. There is
     a pending foreclosure action with respect to the property. Management was
     given until September 1998 to either pay off the mortgage or sell the
     property, or the mortgagor will foreclose on the property. Foreclosure
     proceedings have been initiated by the lender; at September 30, 1998, no
     gain or loss on foreclosure has been recorded and the property has not been
     written off.

     Chapelwood Estates (formerly Cedar Court)
     ----------------------------------------

     provided for annual principal and interest payments of $89,586 payable in

     1, 1996. The property was foreclosed on during 1997 and is no longer owned
     by the Partnership. The foreclosure resulted in a gain for financial
     statement purposes of $150,771.

     The mortgages described above are secured by the Partnership properties to
     which they relate.

6.   INVESTMENT IN JOINT VENTURE
     ---------------------------

     On September 1, 1992, the Partnership entered into an agreement to form a
     joint venture with Realmark Property Investors Limited Partnership VI-B
     (RPILP VI-B). The joint venture was formed for the purpose of operating the
     Lakeview Apartment complex owned by the Partnership. Under the terms of the
     agreement, RPILP VI-B contributed $175,413, with the Partnership
     contributing the property net of the first mortgage.

     The joint venture agreement provides that any income, loss, gain, cash
     flow, or sale proceeds be allocated 83.78% to the Partnership and 16.22% to
     RPILP VI-B. The net loss from the date of inception has been allocated to
     the minority interest in accordance with the agreement and has been
     recorded as a reduction of the capital contribution.

     A reconciliation of the minority interest share in the Lakeview Joint
     Venture is as follows:

7.   RELATED PARTY TRANSACTIONS
     --------------------------

     Management fees for the management of certain of the Partnership's
     properties are paid to an affiliate of the General Partners. The management
     agreement provides for 5% of gross monthly receipts of the complexes to be
     paid as fees for administering the operations of the properties. These fees
     totaled $130,488 and $209,648 for the nine months ended September 30, 1998
     and 1997, respectively.

     The Partnership entered into a management agreement with an unrelated third
     party for the management of Airlane I and III on August 15, 1986. The
     agreement provided for the payment of a management fee equal to 4% of
     monthly gross rental income. An affiliate of the General Partners' also
     received a management fee of 2% of monthly gross rental income. This
     property was sold during the first quarter of 1998 and the management
     agreement was thereafter terminated.

     According to the terms of the Partnership Agreement, the Corporate General
     Partner is also entitled to receive a partnership management fee equal to
     7% of net cash flow (as defined in the Partnership Agreement), 2% of which
     is subordinated to the limited partners having received an annual cash
     return equal to 7% of their average adjusted capital contributions. No such
     fee was paid or accrued by the partnership for the nine months ended
     September 30, 1998 and 1997.

     Accounts payable to affiliates amounted to $1,691,016 and $3,529,210 at
     September 30, 1998 and 1997, respectively. The payable represents fees due
     and advances from the Corporate General Partner or an affiliate of the
     General Partners. Interest charged on accounts payable to affiliates
     totaled $205,223 and $243,005 for the nine months ended September 30, 1998
     and 1997.

     The General Partners are also allowed to collect a property disposition fee
     upon sale of acquired properties. This fee is not to exceed the lesser of
     50% of amounts customarily charged in arm's-length transactions by others
     rendering similar services for comparable properties, or 3% of the sales
     price. The property disposition fee is subordinate to payments to the
     limited partners of a cumulative annual return (not compounded) equal to 7%
     of their average adjusted capital balances and to repayment to the limited
     partners of an amount equal to their original capital contributions. Since
     these conditions have not been met, no fees have been recorded or paid on
     the sale of the Gold Key II apartment complex.

     Computer service charges for the partnerships are paid or accrued to an
     affiliate of the General Partner. The fee is based upon the number of
     apartment units and totaled $8,550 and $9,900 for the nine months ended
     September 30, 1998 and 1997, respectively.

     RELATED PARTY TRANSACTIONS (CONTINUED)
     -------------------------------------

     Pursuant to the terms of the Partnership Agreement, the Corporate General
     Partner charges the Partnership for reimbursement of certain costs and
     expenses incurred by the Corporate General Partner and its affiliates in
     connection with the administration of the Partnership. These charges were
     for the Partnership's allocated share of such costs and expenses which
     include payroll, legal, rent, depreciation, printing, mailing, travel and
     communication costs related to Partnership accounting, partner
     communication and relations and property marketing. Accounting,
     communication and marketing expenses are allocated based on total assets,
     number of partners, and the market value of properties respectively.


8.   INCOME TAXES
     ------------

     No provision has been made for income taxes since the income or loss of the
     partnership is to be included in the tax returns of the Individual
     Partners.

     The tax returns of the Partnership are subject to examination by the
     Federal and state taxing authorities. Under federal and state income tax
     laws, regulations and rulings, certain types of transactions may be
     accorded varying interpretations and, accordingly, reported partnership
     amounts could be changed as a result of any such examination.

     The reconciliation of net income (loss) for the nine months ended September
     30, 1998 and 1997 as reported in the statements of operations, and as would
     be reported for tax purposes, is as follows:

PART II MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        ---------------------------------------------------------------
        RESULTS OF OPERATIONS
        ---------------------

The General Partner continues to fund the Partnership's shortfalls in cash flow,
although under no obligation to do so. Such advances to the Partnership are
considered payable on demand to the General Partner, and at this point in time,
there is no assurance that these advances will continue. The Partnership did not
make any distributions during either of the first three quarters of 1998 or
1997, and is not likely to make any in the future until all Partnership
obligations are satisfied and the General Partner is reimbursed for the advances
it has made to the Partnership.

The General Partner continues its efforts to locate a buyer for the properties
in this Partnership as it is felt that the sale of the properties is in the best
interests of the Limited Partners. Until such time as the properties are sold,
it is highly unlikely that the Limited Partners will receive any return of their
investments. Management is also aggressively seeking refinancing for several of
the properties in an effort to decrease the interest rates currently being paid;
such a decrease will result in lower monthly payments, thus increasing cash
flow. The General Partner was successful in refinancing the Andover Park
Apartment Building (formerly Willow Creek) in Greenville, South Carolina at the
end of June 1998. This refinancing was deemed crucial as the lender was
threatening foreclosure if the mortgage was not paid in full by June 30, 1998.

The General Partner also successfully disposed of two properties in the
Partnership during the first six months of 1998: Airlanes Office/Warehouse
Building located in Nashville, Tennessee and Creekside Apartments located in
Flatrock, Michigan. Both sales resulted in favorable selling prices, and in
addition to paying in full the mortgages secured by both those properties, the
sales also allowed the Partnership to pay some of its other debt.

Management continues to be threatened with foreclosure on both Evergreen Terrace
Apartments located in Lansing, Michigan and Lakeview Apartments located in
Milwaukee, Wisconsin. At this date it is felt that the General Partner will be
unable to prevent the loss of Evergreen Terrace. Management does however feel it
has an interested buyer for Lakeview Village in which case a foreclosure would
be avoided.


                                      -18-
<PAGE>

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

Net loss for the three month period ended September 30, 1998 amounted to
$287,299 or $12.33 per limited partnership unit versus a net loss for the three
month period ended September 30, 1997 of $319,812 or $13.28 per limited
partnership unit. For the nine month period ended September 30, 1998, the net
income amounted to $1,831,389 or $76.03 per limited partnership unit, versus a
net loss of $699,301 or $29.03 per limited partnership unit for the nine month
period ended September 30, 1997. The net income generated during the nine month
period ended September 30, 1998 was due to the gain resulting from the sales of
Airlanes and Creekside which amounted to $3,559,333. Without such gain, the
Partnership incurred a net loss of $1,788,741 or $71.73 per limited partnership
unit for the nine months ended September 30, 1998.

On a tax basis, the Partnership generated income of $1,860,602 or $77.24 per
limited partnership unit for the nine month period ended September 30, 1998
versus a tax loss of $797,089 or $33.09 per limited partnership unit for the
nine month period ended September 30, 1997. Again, without considering the gain
on sale, the tax basis loss which would have been reported for the first nine
months of 1998 was approximately $1,698,731 or $70.52 per limited partnership
unit.

Partnership revenue for the quarter ended September 30, 1998 totaled $788,172, a
decrease of almost $440,000 from the same period in 1997. For the nine month
period ended September 30, 1998 total income decreased by $1,674,229 from the
corresponding period in 1997; total income for the nine months ended September
30, 1998 and 1997 was $2,311,354 and $3,985,583, respectively. Rental income for
the nine month period ended September 30, 1998, totaled $2,145,038, a decrease
of just over $1,580,600 over the same time period in 1997. All the above
decreases are primarily related to the sales of Airlanes Office/Warehouse
Building in February 1998 and Creekside Apartments during March 1998 (i.e.,
there are two less complexes in the Partnership generating revenue). The
decrease is also attributable to extremely low occupancy at Lakeview, which
averaged under 60% and Evergreen Terrace, both properties which are in
receivership at September 30, 1998. Also contributing to the decline in revenues
are continued increased delinquencies at several of the complexes, primarily
Woodbridge Manor (formerly Sutton Park) Apartments located in Lansing, Michigan.

                                      -19-
<PAGE>

Results of Operations (continued):
----------------------------------

For the three month period ended September 30, 1998, the Partnership expenses
totaled $1,102,966, a decrease of approximately $456,000 from the quarter ended
September 30, 1997. For the nine months ended September 30, 1998, the
Partnership expenses totaled $4,100,095, decreasing almost $600,000 from the
same nine month period in the previous year. Property operations costs remain
high, even with the disposal of two properties, due to management's plans to
physically improve the properties in an effort to make them more attractive to
potential renters. Payroll and associated costs and repairs and maintenance
expenses saw large increases between the two nine month periods, and it is
management's expectation that such costs will continue to be relatively high
through the remaining months of 1998 due to necessary capital improvement work
at the properties. Several of the residential complexes in this Partnership are
currently undergoing much needed capital improvement and "fix-up" work,
specifically in the replacement of carpeting and appliances and both interior
and exterior painting. As was noted in the previous quarter, depreciation and
amortization increased dramatically between the nine months ended September 30,
1998 and 1997. The increase was due to two factors: 1) accounting pronouncements
resulted in the ceasing of depreciation on several properties in 1997 due to
existing sales contracts, which were either subsequently canceled or acted upon;
and 2) additional amortization taken on fees paid to extend the Andover Park
(formerly Willow Creek) mortgage and hold off on a pending foreclosure; this
mortgage was subsequently paid in full when a new mortgage was negotiated.
Administrative costs also remained relatively high due to increased brokerage
fees incurred and being accrued as a result of management's increased efforts to
sell the properties in this partnership.

Again, management continues to put forth great effort to control and manage the
Partnership's expenses while also focusing heavily on both increasing
occupancies and improving collections in those complexes that are struggling
financially, such as Woodbridge Manor (formerly Sutton Park).

For the nine month period ended September 30, 1998, the Lakeview Joint Venture
generated net loss of $374,830, with $60,797 of the loss allocated to the
minority venturer. For the nine months ended September 30, 1997, the joint
venture had a net loss of $92,348 with $14,979 of the loss allocated to the
minority venturer. This property is being managed by a receiver appointed by the
mortgagor. The property continues to suffer from low occupancy, a large portion
of which is deemed to be attributable to changing economic and social structure
of the surrounding neighborhood.
