                                     PART I

ITEM 1. BUSINESS

GENERAL

     Sun Communities Operating Limited Partnership, a Michigan limited
partnership (the "Company"), owns, operates and finances manufactured housing
communities concentrated in the midwestern and southeastern United States.  Sun
Communities, Inc., a Maryland corporation and the sole general partner of the
Company ("General Partner"), is a fully integrated real estate company which,
together with its affiliates and predecessors, has been in the business of
acquiring, operating and expanding manufactured housing communities since 1975.
At December 31, 1997, the Company, in conjunction with its subsidiary, Sun
Communities Finance Limited Partnership, a Michigan limited partnership (the
"Financing Partnership"), owned and managed a portfolio of 95 properties
located in twelve states (the "Properties"), including eighty-four manufactured
housing communities, five recreational vehicle communities and six properties
containing both manufactured housing and recreational vehicle sites.  At
December 31, 1997, the Properties contained an aggregate of 28,752 developed
manufactured home sites, approximately 3,600 manufactured home sites suitable
for development and 5,200 recreational vehicle sites.  In order to enhance
property performance and cash flow, the Company, through Sun Home Services,
Inc., a Michigan corporation ("Home Services" or "SHS"), actively markets and
sells new and used manufactured homes for placement in the Properties.

     The General Partner made an election to be taxed as a REIT for federal 
income tax purposes commencing with the calendar year beginning January 1, 
1994, and is self-administered and self-managed.

     The Company's executive and principal property management office is
located at 31700 Middlebelt Road, Suite 145, Farmington Hills, Michigan 48334
and its telephone number is (248) 932-3100.  The Company has regional property
management offices located in Elkhart, Indiana and Tampa, Florida.  The
Company employed 547 people as of December 31, 1997.

HISTORY OF THE COMPANY

     The immediate predecessor to Sun Communities, Inc. was incorporated in
January 1985 to continue and expand the business of acquiring, owning and
operating manufactured housing communities that was originally started in 1975.
Since its inception, the General Partner's strategy has been to acquire and in
many cases expand or renovate existing manufactured housing communities.  The
General Partner has maintained this strategy because it believes attractive
investment returns can be obtained by purchasing existing properties with
expansion potential.

STRUCTURE OF THE COMPANY

     The operations of the General Partner are carried on through certain
subsidiaries (the "Subsidiaries"), including the Company and the Financing
Partnership, which, among other things, enables the General Partner to  comply
with certain complex requirements under the Federal tax rules and regulations
applicable to REITs.  The General Partner established the Company to allow the
General Partner to acquire   manufactured housing communities in transactions
that defer some or all of the sellers' tax consequences.  Substantially all of
the General Partner's assets are held by or through the Company, of which the
General Partner is the sole general partner, and wholly-owned subsidiaries of
the Company.  In addition to the Company and the Financing Partnership, the
Subsidiaries include Home Services, which provides manufactured home sales and
other services to current and prospective tenants of the Properties.  The
Company owns 100% of the non-voting

                                    - 2 -


<PAGE>   3

preferred stock of Home Services, which entitles the Company to 95% of the cash
flow from operating activities of Home Services.  The voting common stock of
Home Services is owned by Milton M. Shiffman, Gary A. Shiffman and Jeffrey P.
Jorissen, executive officers of the General Partner, entitling them to the
remaining 5% of such cash flow from operating activities.  Sun Water Oak Golf,
Inc. ("Sun Golf") is a wholly-owned subsidiary of Home Services.  Sun Golf was
organized to own and operate the golf course, restaurant and related facilities
located on the Water Oak Property that were acquired in November 1994.

THE MANUFACTURED HOUSING COMMUNITY INDUSTRY

     A manufactured housing community is a residential subdivision designed and
improved with sites for the placement of manufactured homes and related
improvements and amenities.  Manufactured homes are detached, single-family
homes which are produced off-site by manufacturers and installed on sites
within the community.  Manufactured homes are available in a wide array of
designs, providing owners with a level of customization generally unavailable
in other forms of multi-family housing.

     Modern manufactured housing communities, such as the Properties, contain
improvements similar to other garden-style residential developments, including
centralized entrances, paved streets, curbs and gutters, and parkways.  In
addition, these communities also often provide a number of amenities, such as a
clubhouse, a swimming pool, shuffleboard courts, tennis courts, laundry
facilities and cable television service.

     The owner of each home in the Company's communities leases the site on
which the home is located.  The Company owns the underlying land, utility
connections, streets, lighting, driveways, common area amenities and other
capital improvements and is responsible for enforcement of community guidelines
and maintenance.  Some communities provide water and sewer service through
public or private utilities, while others provide these services to residents
from on-site facilities.  Each owner within the Company's communities is
responsible for the maintenance of his home and leased site.  As a result,
capital expenditure needs tend to be less significant, relative to multi-family
rental apartment complexes.

PROPERTY MANAGEMENT

     The Company's property management strategy emphasizes intensive, hands-on
management by dedicated, on-site property managers.  The Company believes that
this on-site focus enables it to continually monitor and address tenant
concerns, the performance of competitive properties and local market
conditions.  Of the Company's 547 employees, 499 are located on-site as
property managers, support staff, or maintenance personnel.

     The Company's property managers are overseen by Brian W. Fannon, Senior
Vice President and Chief Operating Officer of the General Partner, who has 28
years of property management experience, three Vice Presidents and eleven
Regional Property Managers.  In addition, the Regional Property Managers are
responsible for semi-annual market surveys of competitive parks, interaction
with local manufactured home dealers and regular property inspections.

     Each property manager performs regular inspections in order to continually
monitor the property's physical condition and provides managers with
the opportunity to understand and effectively address tenant concerns.  In
addition to a property manager, each property has an on-site maintenance person
and management support staff.  The Company holds periodic training sessions for
all property management personnel to ensure that management policies are
implemented effectively and professionally.

                                    - 3 -

HOME SALES

     Home Services offers manufactured home sales services to tenants and
prospective tenants in the Company's communities.  Since tenants often purchase
a home already on-site within a community, such services enhance occupancy and
property performance.  Additionally, since many of the homes in the Properties
are sold through Home Services, better control of home quality in the Company's
communities can be maintained than if sales services were conducted solely
through third-party brokers.

COMPETITION

     All of the Properties are located in developed areas that include other
manufactured housing community properties.  The number of competitive
manufactured housing community properties in a particular area could have a
material effect on the Company's ability to lease sites and on rents charged at
the Properties or at any newly acquired properties.  The Company may be
competing with others that have greater resources than the Company and whose
officers and directors have more experience than the Company's officers and
directors.  In addition, other forms of multi-family residential properties,
such as private and federally funded or assisted multi-family housing and
single-family housing, provide housing alternatives to potential tenants of
manufactured housing communities.

REGULATIONS AND INSURANCE

     General.  Manufactured housing community properties are subject to various
laws, ordinances and regulations, including regulations relating to
recreational facilities such as swimming pools, clubhouses and other common
areas.  The Company believes that each Property has the necessary operating
permits and approvals.

     Americans with Disabilities Act ("ADA").  The Properties and any newly
acquired manufactured housing communities must comply with the ADA.  The ADA
has separate compliance requirements for "public accommodations" and
"commercial facilities," but generally requires that public facilities such as
clubhouses, pools and recreation areas be made accessible to people with
disabilities.  Compliance with ADA requirements could require removal of access
barriers and other capital improvements at the Company's properties.
Noncompliance could result in imposition of fines or an award of damages to
private litigants.  The Company does not believe the ADA will have a material
adverse impact on the Company's results of operations.  If required property
improvements involve a greater expenditure than the Company currently
anticipates, or if the improvements must be made on a more accelerated basis
than it anticipates, the Company's ability to make expected distributions could
be adversely affected.  The Company believes that its competitors face similar
costs to comply with the requirements of the ADA.

     Rent Control Legislation.  State and local rent control laws in certain
jurisdictions limit the Company's ability to increase rents and to recover
increases in operating expenses and the costs of capital improvements.
Enactment of such laws has been considered from time to time in other   
jurisdictions.  The Company presently expects to continue to operate
manufactured housing community properties, and may purchase additional
properties, in markets that are either subject to rent control or in which
rent-limiting legislation exists or may be enacted.  For example, 29 of the
Properties are located in Florida, which has enacted a law which provides that
a majority of tenants in a manufactured housing community may require that a
proposed increase in site rental rates, reduction in services or utilities or
change in the community's rules and regulations be submitted for formal
mediation or arbitration if they believe that the proposal is
unreasonable.

     Insurance.  Management believes that the Properties are covered by
adequate fire, flood, property and business interruption insurance provided by
reputable companies and with

                                    - 4 -


<PAGE>   5

commercially reasonable deductibles and limits.  The Company maintains a
blanket policy that covers all of the Properties.  The Company has obtained
title insurance insuring fee title to the Properties in an aggregate amount
which the Company believes to be adequate.

ITEM 2. PROPERTIES

     General.  At December 31, 1997, the Properties consisted of eighty-four
manufactured housing communities, five recreational vehicle communities and six
properties containing both manufactured housing and recreational vehicle sites
concentrated in twelve states in the midwestern and southeastern United States.
At December 31, 1997, the Properties contained 28,752 developed manufactured
home sites, approximately 3,600 manufactured home sites suitable for
development and 5,200 recreational vehicle sites.  Most of the Properties
include amenities oriented towards family and retirement living.  Of the 95
Properties, forty-four have more than 300 developed manufactured home sites,
with the largest having 913 developed manufactured home sites.

     The Properties had an aggregate occupancy rate of 95% as of December 31,
1997, excluding recreational vehicle sites.  Since January 1, 1997, the
Properties have averaged an aggregate annual turnover of homes (where the home
is moved out of the community) of approximately 2.8% and an average annual
turnover of residents (where the home is sold and remains within the community,
typically without interruption of rental income) of approximately 8.5%.

     The Company believes that its Properties' high amenity levels contribute
to low turnover and generally high occupancy rates.  All of the Properties
provide residents with attractive amenities with most offering a clubhouse, a
swimming pool, laundry facilities and cable television service.  Many
Properties offer additional amenities such as sauna/whirlpool spas, tennis,
shuffleboard and basketball courts and/or exercise rooms.

     The Company has sought to concentrate its communities within certain
geographic areas in order to achieve economies of scale in management and
operation.  Except for five Properties located in Texas and one property
located in Colorado, the Properties are located in the midwestern and
southeastern United States.  The Company has identified Florida as a key market
in which to expand its existing operations in the southeast because of
Florida's stable tenant base, relatively low cost of living and attractive
acquisition opportunities.  Additionally, the Company's midwestern operations
serve as a source of prospective tenants for the Florida Properties, which are
generally oriented towards retirement living. Because the Company believes that
geographic diversification will help insulate the portfolio from regional
economic influences, the Company is also interested in acquiring properties in
the western United States.

(1)  Excludes 5,200 recreational vehicle sites owned at December 31, 1997.

(2)  Occupancy in these Properties reflects the recent development of sites
     which are in their initial lease-up phase.

(3)  This Property is owned by a joint venture in which the Company has a
     50% interest.

(4)  Acquired in 1996.

(5)  Acquired in 1997.

(6)  Occupancy in these Properties reflects the fact that these communities
     are in their initial lease-up phase.

(7)  This Property contains only recreational vehicle sites.

(8)  The Company leases this Property.  The Company has the option to purchase
     the Property upon the expiration of the lease.  If the Company does not
     exercise its option to purchase, the lessor has the right to cause the
     Company to purchase the Property at the expiration of the lease at the
     option price.

(9)  This Property also contains recreational vehicle sites.


            Leases.  The typical lease entered into between a tenant and the 
Company for the rental of a site is month-to-month or year-to-year, renewable
upon the consent of both parties, or, in some instances, as provided by
statute.  In some cases, leases are for one-year terms, with up to ten renewal
options exercisable by the tenant, with rent adjusted for increases in the
consumer price index.  These leases are cancelable for non-payment of rent,
violation of community rules and regulations or other specified defaults.  See
"Regulations and Insurance."

ITEM 3.     LEGAL PROCEEDINGS

            Certain partnerships which previously owned twenty-four of the 
Properties (the "Sun Partnerships") were involved in a variety of legal
proceedings arising in the ordinary course of business prior to the transfer of
the Properties to the Company, and the Company has become a successor
party-in-interest to these proceedings as a result of the contribution of the
Properties to the Company, as well as other proceedings that have arose in the
ordinary course of operating the Properties.  All such proceedings, taken
together, are not expected to have a material adverse impact on the Company's
business or financial condition.

ITEM 4.     SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

            No matters were submitted to a vote of the Company's security 
holders during the fourth quarter of the fiscal year covered by this report.

ITEM 7.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS

OVERVIEW

     The following discussion and analysis of the consolidated financial
condition and results of operations should be read in conjunction with the
Consolidated Financial Statements and notes thereto.

RESULTS OF OPERATIONS

Comparison of year ended December 31, 1997 to year ended December 31, 1996

     For the year ended December 31, 1997, income before extraordinary item
increased by $5.9 million from $22.0 million to $27.9 million, when compared to
the year ended December 31, 1996.  The increase was due to increased revenues
of $23.0 million while expenses increased by $17.1 million.

     Income from property increased by $21.9 million from $71.3 million to
$93.2 million due primarily to the acquisition of communities comprising
approximately 5,200 developed sites during 1997 and 29 communities comprising
in excess of 11,300 developed sites during 1996.

     Income from Home Services and Bingham Financial Services Corporation
("Bingham" or "BFSC") increased by $1.0 million to $1.5 million from $.5
million due to increased sales of homes and the financing operations of the
Company's newly formed affiliate, Bingham.

     Property operating and maintenance expenses increased by $5.1 million from
$16.0 million to $21.1 million due primarily to the acquired communities.

     Real estate taxes increased by $1.8 million from $5.7 million to $7.5
million due primarily to the acquired communities.

     General and administrative expenses increased by $1.0 million from $3.5
million to $4.5 million due primarily to additional staff as a result of the
Company's growth.

     Interest expense increased by $3.2 million from $11.3 million to $14.5
million due primarily to $150 million Senior Notes which were issued May 1,
1996.  Included in interest is amortization of deferred finance costs of $.2
million in 1997 and 1996.

     Earnings before interest, taxes, depreciation and amortization ("EBITDA")
increased by $15.0 million from $48.1 million to $63.1 million.  EBITDA as a
percent of revenues was 65.6% compared to 65.7% in 1996.

     Depreciation and amortization expense increased by $5.8 million from $14.9
million to $20.7 million due primarily to the acquisition of communities in 
1997 and 1996.

Comparison of year ended December 31, 1996 to year ended December 31, 1995

     For the year ended December 31, 1996, income before extraordinary item
increased by $8.4 million from $13.6 million to $22.0 million, when compared to
the year ended December 31, 1995.  The increase was due to increased revenues
of $28.1 million while expenses increased by $19.7 million.

     Income from property increased by $27.3 million from $44.0 million to
$71.3 million due primarily to the acquisition of 29 communities comprising in
excess of 11,300 developed sites during 1996 and six additional communities
comprising in excess of 2,200 developed sites during 1995.

     Other income increased by $.7 million from $.7 million to $1.4 million due
to higher levels of interest income resulting primarily from investment of
proceeds of financings and interest on mortgage notes receivable for a full
year in 1996.

     Property operating and maintenance expenses increased by $6.2 million from
$9.8 million to $16.0 million due primarily to the acquired communities.

     Real estate taxes increased by $2.7 million from $3.0 million to $5.7
million due primarily to the acquired communities.

     General and administrative expenses increased by $1.0 million from $2.5
million to $3.5 million due primarily to additional staff as a result of the
Company's growth.

     Interest expense increased by $4.9 million from $6.4 million to $11.3
million due to higher levels of borrowings at a slightly higher weighted
average interest rate. Included in interest is amortization of deferred finance
costs of $.2 million and $.6 million in 1996 and 1995, respectively.

     EBITDA increased by $18.3 million from $29.8 million to $48.1 million.
EBITDA as a percent of revenues was 65.7% compared to 66.0 % in 1995.

     Depreciation and amortization expense increased by $5.2 million from $9.7
million to $14.9 million due primarily to the acquisition of communities in
1996 and 1995.

SAME PROPERTY INFORMATION

     The following table reflects property-level financial information as of
and for the years ended December 31, 1997 and 1996.  The "Same Property" data
represents information regarding the operation of communities owned as of
January 1, 1996.  Site, occupancy, and rent data for those communities is
presented as of the last day of each period presented.  The table includes
sites where the Company's interest is in the form of shared appreciation notes
or where the Company is providing financing and managing the properties.  Such
amounts relate to 1,873 sites in 1997 and 1,218 sites in 1996 and were formerly

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

    (1)  Occupancy % and weighted average rent relates to manufactured housing
    sites, excluding recreational vehicle sites.

    (2)  Includes 750 sites related to zoned land.

     On a same property basis, property revenues increased by $3.5 million from
$48.7 million to $52.2 million, or 7.2 percent, due primarily to increases in
rents and occupancy related charges including water and property tax pass
throughs.  Also contributing to revenue growth was the increase of 550 leased
sites at December 31, 1997 compared to December 31, 1996 and the increase in
weighted average monthly rent per site from $241 in 1996 to $251 in 1997.

     Property operating expenses increased by $.6 million from $13.4 million to
$14.0 million, or 4.7 percent, due to increased occupancies and costs and
increases in assessments and millage by local taxing authorities.  Property
EBITDA increased by $2.9 million from $35.4 million to $38.3 million, or 8.2
percent.

     Sites available for development in the total portfolio increased by 373
from 3,268 to 3,641. 

LIQUIDITY SOURCES AND REQUIREMENTS

     Cash and cash equivalents decreased by $7.0 million to $2.2 million at
December 31, 1997 compared to $9.2 million at December 31, 1996 primarily       
because cash used in investing activities exceeded cash provided by operating
and financing activities.

                                    - 15 -


<PAGE>   16



     Net cash provided by operating activities increased by $4.8 million from
$35.4 million to $40.2 million for the year ended December 31, 1997 as compared
to the year ended December 31, 1996.  This increase was due primarily to a
$16.4 million increase in income before depreciation and amortization and
extraordinary item offset by a $4.3 million increase in other assets and a $7.4
million decrease in accounts payable and other liabilities.

     Net cash used in investing activities increased by $30.8 million from
$76.9 million to $107.7 million for the year ended December 31, 1997 as
compared to the year ended December 31, 1996.  This was due to increased
investments in notes and affiliates.

     Net cash provided by financing activities increased by $9.8 million from
$50.6 million to $60.5 million for the year ended December 31, 1997 as compared
to the year ended December 31, 1996.  This increase was due to an increase in
net borrowings, including deferred financing costs, of $113.9 million offset
by a reduction in capital contributons net of distributions of $104.1 million.


     The Company expects to meet its short-term liquidity requirements
generally through its working capital provided by operating activities. The
Company expects to meet certain long-term liquidity requirements such as
scheduled debt maturities and property acquisitions through the issuance of
debt securities, or general or limited partnership interests. The Company
considers these sources to be adequate and anticipates they will continue to be
adequate to meet operating requirements, capital improvements, investment in
development, and payment of distributions by the Company in both the short and
long term. The Company can also meet these short-term and long-term
requirements by utilizing its $75 million line of credit which bears interest
at LIBOR plus .90% and is due November 1, 1999.

     At December 31, 1997, the Company's debt to total market capitalization
approximated 28.8% (assuming conversion of all Preferred OP Units), with a
weighted average maturity of approximately 5.9 years and a weighted average
interest rate of 7.23%.

     Capital expenditures for 1997 included recurring capital expenditures of
$4.6 million, including $.4 million for additional space and related costs at
corporate headquarters,  and revenue producing capital expenditures of $1.2
million which principally consisted of water metering programs.

     Development costs including land acquisitions of $0.2 million aggregated
$17.5 million for the year ended December 31, 1997.

RATIO OF EARNINGS TO FIXED CHARGES

     The Company's ratio of earnings to fixed charges for the years ended
December 31, 1995, 1996, and 1997 was  3.03:1, 2.49:1, and 2.40:1,
respectively.

INFLATION

     Most of the leases allow for periodic rent increases which provide the
Company with the opportunity to achieve increases in rental income as each
lease expires.  Such types of leases generally minimize the risk of inflation 
to the Company.

OTHER

     The Company does not anticipate the Year 2000 compliance requirements will
have a material impact on earnings.  The Company has initiated replacement of
the Company's most significant computer programs with new updates that are
warranted to be Year 2000 compliant.  Installation of

                                    - 16 -


<PAGE>   17

these updates is anticipated to be completed prior to December 31, 1998.  All
other programs subject to Year 2000 concerns will be evaluated utilizing
internal and external resources to re-program, replace or test each of them.  A
formal communication plan with significant third party vendors will be
initiated during 1998 to determine their Year 2000 compliance programs.

     Industry analysts consider funds from operations ("FFO") to be an
appropriate measure of the performance of an equity REIT.  It is defined as
income before minority interests plus non-cash items such as depreciation and
amortization.  FFO should not be considered as an alternative to net income as
an indication of the Company's performance or to cash flows as a measure of
liquidity.

     The following table presents FFO for each of the quarters during 1997, 
1996 and 1995:

REPORT OF INDEPENDENT ACCOUNTANTS


To the Partners of Sun Communities
Operating Limited Partnership:

We have audited the accompanying consolidated balance sheet of Sun Communities  
Operating Limited Partnership as of December 31, 1997 and 1996, and the related
consolidated statements of income, partners' capital, and cash flows for each
of the three years in the period ended December 31, 1997.  We have also audited
the consolidated financial statement schedule listed under 14(a)(2) of this
form 10-K.  These financial statements and the financial statement schedule are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements and the financial statement
schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Sun Communities
Operating Limited Partnership as of December 31, 1997 and 1996 and the
consolidated results of its operations and cash flows for each of the three
years in the period ended December 31, 1997 in conformity with generally
accepted accounting principles.  In addition, in our opinion, the financial
statement schedule referred to above, when considered in relation to the
consolidated financial statements taken as a whole, presents  fairly, in all
material respects, the information stated therein.

2. SUMMARY OF SIGNIFICANT ACCOUNTING
   POLICIES:

   A. BUSINESS: The Company and its subsidiaries own and operate or finance 99
      manufactured housing communities located in 13 states concentrated
      principally in the Midwest and Southeast comprising approximately 36,000
      developed sites and approximately 3,600 sites suitable for development.

      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 dates of the
      financial statements  and the reported amounts of revenues and expenses
      during the reporting periods.  Actual results could differ from those
      estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING
   POLICIES, CONTINUED:

   B.   PRINCIPLES OF CONSOLIDATION:  The accompanying financial statements
        include the accounts of the Company and all its 99 percent owned        
        subsidiary partnerships and limited liability companies.  All
        significant inter-entity balances and transactions have been
        eliminated in consolidation. The limited partnership interests are
        adjusted to their relative ownership interest by reclassification
        to/from general partnership interests.   Minority interests represented
        by Sun's one percent indirect interest in the aforementioned
        subsidiaries is not separately recognized in the Company's financial
        statements because the Company reimburses Sun for all of its expenses
        in excess of the income Sun earns through its one percent interest.

        Also included in these financial statements are 1.3 million Preferred
        OP Units ("POP Units") issued at $27 per unit bearing a quarterly
        distribution of 7% and are redeemable at par in June, 2002.  The POP
        Units are convertible one-for-one into OP Units based upon the current  
        trading price of Sun's common stock up to $31.50 per unit.  At prices
        above $31.50 per unit, the POP Units are convertible into OP Units
        based on a formula the numerator of which is $31.50 plus 25 percent of
        unit price appreciation above $36 per unit.  The denominator is the
        then unit price.  Had conversion occurred at Sun's December 31, 1997 
        stock price of $35.94, the 1.325 million POP Units Sun's would have 
        converted into 1.161 million OP Units.

        SHS provides home sales and other services to current and prospective   
        tenants.  The Company owns 100 percent of the outstanding preferred
        stock of SHS, is entitled to 95 percent of the operating cash flow,
        and accounts for its investment utilizing the equity method of
        accounting.  The common stock is owned by three officers of the Company
        who are entitled to receive 5 percent of the operating cash flow.

        BFSC provides financing to current and prospective tenants.  The
        Company owns 25,000 common shares or 2% of BFSC.  The Company has
        730,000 warrants exercisable at prices ranging from $10 to $14 per
        share from 2001 through 2018.  The market price of BFSC stock at
        December 31, 1997 was $10.

   C.   RENTAL PROPERTY:  Rental property is recorded at the lower
        of cost, less accumulated  depreciation or fair value. Management
        evaluates the recoverability of its investment in rental property
        whenever events or changes in circumstances such as recent operating
        results, expected net operating cash flow and plans for future
        operations indicate that full asset recoverability is questionable.

        Depreciation is computed on a straight-line basis over
        the estimated useful lives of the assets.  Useful lives are 30 years
        for land improvements and buildings and 7 to 15 years for furniture,
        fixtures and equipment.  Expenditures for ordinary maintenance and
        repairs are charged to operations as incurred and significant
        renovations and improvements, which improve and/or extend the useful
        life of the asset, are capitalized and depreciated over their estimated
        useful lives.

   D.   CASH AND CASH EQUIVALENTS:  The Company considers all highly
        liquid  investments with an initial maturity of three months or less to
        be cash and cash equivalents.

   E.   REVENUE RECOGNITION:  Rental income attributable to leases is
        recorded on a straight-line basis when earned from tenants.  Leases
        entered into by tenants range from month-to-month to twelve years and
        are renewable by mutual agreement of the Company and resident or, in
        some cases, as provided by statute.

   F.   FAIR VALUE OF FINANCIAL INSTRUMENTS:  The carrying amount of financial  
        instruments which includes cash and cash investments, mortgages and
        notes receivable and debt approximates fair value.

   G.   TAXES: As a partnership, the Company does not pay federal or state
        income taxes.

2. SUMMARY OF SIGNIFICANT ACCOUNTING
   POLICIES, CONTINUED:

   H.   CASH FLOW HEDGES: The Company periodically enters into hedge
        transactions utilizing Treasury securities to lock-in the basic
        interest cost of financing acquisitions.  The gain or loss on such
        hedges is amortized as an adjustment to interest expense over the term
        of the related financing.

   I.   RECLASSIFICATIONS:  Certain 1995 and 1996 amounts have been
        reclassified to conform with the 1997 financial statement presentation.
        Such reclassifications have no effect on operations as originally
        presented.

3. ACQUISITIONS:

   During 1997, the Company acquired 12 manufactured housing communities        
   comprising 4,258 developed sites and 425 sites suitable for development. 
   The cost of acquisitions aggregated $69.8 million excluding $4.5 million of
   future payments contingent upon certain events.  Consideration consisted of
   $51.3 million in cash and $18.5 million in capitalized lease obligations.

   During 1996, the Company acquired 29 manufactured housing communities        
   comprising in excess of 11,350 developed sites and 500 sites suitable for
   development for $247.9 million. Consideration consisted of $134.1 million in
   the assumption or issuance of debt, $53.4 million in issuance of Common and
   Preferred OP Units and $60.4 million of cash.

   These transactions have been accounted for as purchases, and the statements
   of income include the operations of the acquired communities from the
   dates of their respective acquisitions.  In conjunction with an acquisition,
   the Company is obligated to issue $12.1 million of OP Units over the
   expected lease-up of the community through 2009 based on the per unit price
   of the OP Units on each annual date.

   The following unaudited table of pro forma information has been prepared as
   if the Company's acquisition of 29 manufactured housing communities in
   1996 and 12 manufactured housing communities in 1997 had occurred as of
   January 1, 1996. In management's opinion, the pro forma information is not
   necessarily indicative of consolidated results of operations that may have
   occurred had the above transactions taken place on January 1 of each year. 
   In the following table, the amounts are in thousands except per unit

</TABLE>


The Company has a $75 million unsecured line of credit at LIBOR plus .90%
maturing in November, 1999, of which $58 million  was available at December 31,
1997.  The interest rate at December 31, 1997 was 6.89%.

The  term loan is collateralized by 7 communities comprising approximately
3,400 sites.  Annual payments under capitalized lease obligations range from
$1.3 million to $1.4 million during their terms.  The extraordinary item of
$6.9 million in 1996 results from the early extinguishment of debt and includes
prepayment penalties and related deferred financing costs.

At December 31, 1997, the Company has Treasury Rate Locks for a total notional
amount of $88.7 million and an unrealized loss of $1.5 million for the purpose
of hedging against the potential for increased interest expense on anticipated
future fixed rate financings.  At the present time, the Company anticipates
issuing fixed rate securities in 1998 with a maturity of at least five to ten
years.  Should medium term interest rates increase, the value of the Treasury
Rate Locks will increase offsetting a portion of the additional interest
expense incurred.  Alternatively, should medium term interest rates decrease,
the Company will incur costs which would be offset by lower interest expense.

At December 31, 1997, the maturities of debt during the next five years were
approximately as follows: 1998 - $.8 million; 1999 - $.8 million; 2000 - $.9
million; 2001 $66.0 million; and 2002 - $16.6 million.

     $22.28, respectively.  There are 628,200 and 182,620 options outstanding
     and exercisable, respectively, which range from $28.00 - $35.99.  The
     weighted average exercise price for these outstanding and exercisable
     options is $30.26 and $28.70, respectively.  The weighted average
     contractual life of outstanding options is 6.9 years.


Sun's stock option plans provide for up to 1.6 million shares/units of common
stock/partnership interests that may be granted to directors, executive
officers and other key employees of Sun or the Company.  At December 31, 1997,
432,000 shares/units of common stock/partnership interests were available for
the granting of options.  Options are granted at fair market value and
generally vest over a two-year period and may be exercised for 10 years after
date of grant.  In addition, the Company established a Long-Term Incentive Plan
for its nonexecutive officer employees permitting a grant of up to 240,000
options which were granted in 1997, and become exercisable in equal
installments in 2002-2004 based on corporate profit performance.

The Company has opted to measure compensation cost utilizing the intrinsic
value method.  The fair value of each option grant was estimated as of the date
of grant using the Black-Scholes option-pricing model with the following
assumptions for options granted in:

Estimated fair value per share/unit of options granted during year ..  $2.82   $1.94

Assumptions:
    Annualized dividend yield........................................   7.1%    6.9%
    Common stock/partnership interest price volatility...............  15.6%   15.1%
    Risk-free rate of return.........................................   6.7%    6.2%
    Expected option term (in years)..................................      7       8
</TABLE>

If compensation cost for stock option grants had been recognized based on the
fair value at the grant date, this would have resulted in net income of $25.0
million and $13.2 million and net income per OP Unit of $1.36 and $.84 in 1997
and 1996, respectively.

   Diluted earnings per OP Unit reflect the potential dilution that would occur
   if securities were exercised or converted into OP Units.  Convertible POP
   Units are excluded from the computations as their inclusion would have an
   anti-dilutive effect on earnings per OP Unit in 1997 and 1996.
