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, 1998, 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 102 developed
properties located in fourteen states (the "Properties"), including 91
manufactured housing communities, 5 recreational vehicle communities and 6
properties containing both manufactured housing and recreational vehicle sites.
At December 31, 1998, the Properties contained an aggregate of 31,512 developed
manufactured home sites, approximately 2,500 manufactured home sites suitable
for development and approximately 5,100 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 Indianapolis, Indiana, Orlando, Florida and
Austin, Texas. The Company employed 552 people as of December 31, 1998.

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 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.



3

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 community 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 552 employees, 492 are located on-site as property
managers, support staff, or maintenance personnel.

The Company's community managers are overseen by Brian W. Fannon,
Senior Vice President and Chief Operating Officer of the General Partner, who
has 29 years of property management experience, two Senior Vice Presidents, four
Regional Vice Presidents and twelve Regional Property Managers. In addition, the
Regional Property Managers are responsible for semi-annual market surveys of
competitive communities, interaction with local manufactured home dealers and
regular property inspections.

Each community 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 community 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.



4

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, 27 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.


5


Insurance. Management believes that the Properties are covered by
adequate fire, flood, property and business interruption insurance provided by
reputable companies and with 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, 1998, the Properties consisted of 91
manufactured housing communities, 5 recreational vehicle communities and 6
properties containing both manufactured housing and recreational vehicle sites
concentrated in fourteen states in the midwestern and southeastern United
States. At December 31, 1998, the Properties contained 31,512 developed
manufactured home sites, approximately 2,500 manufactured home sites suitable
for development and approximately 5,100 recreational vehicle sites. In addition,
at December 31, 1998, the Company owned nine undeveloped properties on which the
Company plans to develop approximately 4,400 manufactured home sites. Most of
the Properties include amenities oriented towards family and retirement living.
Of the 102 Properties, 47 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 94.2% as of December
31, 1998, excluding recreational vehicle sites. Since January 1, 1998, the
Properties have averaged an aggregate annual turnover of homes (where the home
is moved out of the community) of approximately 3% 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%.

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 each of Colorado, Nevada and Oregon, 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.

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, 1998 to year ended December 31, 1997

For the year ended December 31, 1998, income before other, net
increased by $3.5 million from $27.9 million to $31.4 million, when compared to

$24.3 million while expenses increased by $20.9 million.

Income from property increased by $21.1 million from $93.2 million to
$114.3 million due primarily to the acquisition of 10 communities comprising
approximately 2,100 developed sites during 1998 and 14 communities comprising
approximately 5,200 developed sites during 1997.

Income from affiliates increased by $2.9 million to $4.4 million from
$1.5 million due to increased sales of homes by Sun Home Services, Inc. ("SHS")
and interest income earned on advances to Bingham Financial Services Corporation
("BFSC").

Property operating and maintenance expenses increased by $4.5 million
from $21.1 million to $25.6 million due primarily to the acquired communities.

Real estate taxes increased by $1.2 million from $7.5 million to $8.7
million due primarily to the acquired communities.

to $2.3 million representing 2.0 percent of income from property in 1998 and
1997.

General and administrative expenses increased by $.7 million from $2.6
million to $3.3 million due primarily to additional staff and facilities as a
result of the Company's growth.

Interest expense increased by $9.7 million from $14.5 million to $24.2
million due primarily to investments in rental property. Included in interest is
amortization of deferred finance costs of $.7 million and $.2 million in 1998
and 1997, respectively.

Earnings before interest, taxes, depreciation and amortization
("EBITDA") increased by $17.5 million from $63.1 million to $80.6 million.
EBITDA as a percent of revenues was 66.8% compared to 65.6% in 1997.

$20.7 million to $25.0 million due primarily to the acquisition of communities
in 1998 and 1997.

Included in other, net of $.6 million are $1.5 million in net gains on
asset sales offset by $.9 million related to an unsuccessful portfolio
acquisition.

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

For the year ended December 31, 1997, income before other, net and
extraordinary item increased by $5.9 million from $22.0 million to $27.9
million, when compared to the year ended


14

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 and financing of 14 communities

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.

Property management expenses increased by $.7 million to $1.9 million
from $1.2 million representing 2.0 percent and 1.7 percent of income from
property in 1997 and 1996, respectively.

General and administrative expenses increased by $.4 million from $2.2
million to $2.6 million due primarily to additional staff and facilities 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.

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.

SAME PROPERTY INFORMATION

The following table reflects property-level financial information as of
and for the years ended December 31, 1998 and 1997. The "Same Property" data
represents information regarding the operation of communities owned as of
January 1, 1997. 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 766 sites in 1998 and 1,873 sites in 1997.

Sites under development 145 542 2,019 904



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

On a same property basis, property revenues increased by $5.4 million
from $70.6 million to $76.0 million, or 7.6 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 575 leased
sites at December 31, 1998 compared to December 31, 1997.

Property operating expenses increased by $.9 million from $19.9 million
to $20.8 million, or 4.4 percent, due to increased occupancies and costs and
increases in assessments and millage by local taxing authorities. Property
EBITDA increased by $4.5 million from $50.7 million to $55.2 million, or 8.9
percent.

LIQUIDITY SOURCES AND REQUIREMENTS

Net cash provided by operating activities increased by $12.4 million
from $40.2 million to $52.6 million for the year ended December 31, 1998 as
compared to the year ended December 31, 1997. This increase was due primarily to
a $7.8 million increase in income before depreciation and amortization and
other, net and a $6.3 million increase in accounts payable and other liabilities
offset by a $2.1 million increase in other assets.

Net cash used in investing activities decreased by $1.8 million from
$107.7 million to $105.9 million for the year ended December 31, 1998 as
compared to the year ended December 31, 1997. This was due to a $7.7 million
reduction of cash used for notes receivable and investment in and advances to
affiliates offset by a $5.9 million increase in investment in rental properties,
net of proceeds from asset sales.
16

Net cash provided by financing activities increased by $.2 million from
$60.5 million to $60.7 million for the year ended December 31, 1998 as compared
to the year ended December 31, 1997. This increase was due to a $12.8 million
increase in proceeds from net borrowings including payments for deferred
financing costs, offset by an increase of $3.3 million in distributions and a
$9.2 million reduction in capital contributions.

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 $100 million line of credit which bears interest at LIBOR
plus .90% and is due November 1, 1999.

At December 31, 1998, the Company's debt to total market capitalization
approximated 32.4% (assuming conversion of all Preferred OP Units), with a
weighted average maturity of approximately 6.1 years and a weighted average
interest rate of 7.07%.

Capital expenditures for 1998 included recurring capital expenditures of
$5.3 million including $.4 million for additional space and related costs at
corporate headquarters and revenue producing capital expenditures of $.9 million
which principally consisted of water metering programs.

RATIO OF EARNINGS TO FIXED CHARGES

The Company's ratio of earnings to fixed charges for the years ended
December 31, 1998, 1997, and 1996 was 2.04:1, 2.40:1, and 2.49:1 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.

SAFE HARBOR STATEMENT

This Form 10-K contains various "forward-looking statements" within the
meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934,
and the Company intends that such forward-looking statements be subject to the
safe harbors created thereby. The words "may", "will", "expect", "believe",
"anticipate", "should", "estimate", and similar expressions identify
forward-looking statements. These forward-looking statements reflect the
Company's current views with respect to future events and financial performance,
but are based upon current assumptions regarding the Company's operations,
future results and prospects, and are subject to many uncertainties and factors
relating to the Company's operations and business environment which may cause
the actual results of the Company to be materially different from any future
results expressed or implied by such forward-looking statements. Please see the
section entitled "Risk Factors" of the Company's Registration Statement on Form
S-3 filed with the Securities and Exchange Commission on February 16, 1999 for a
list of uncertainties and factors.

Such factors include, but are not limited to, the following: (i) changes
in the general economic climate; (ii) increased competition in the geographic
areas in which the Company owns and operates


17

manufactured housing communities; (iii) changes in government laws and
regulations affecting manufactured housing communities; and (iv) the ability of
the Company to continue to identify, negotiate and acquire manufactured housing
communities and/or vacant land which may be developed into manufactured housing
communities on terms favorable to the Company. The Company undertakes no
obligation to publicly update or revise any forward-looking statements whether
as a result of new information, future events, or otherwise.

YEAR 2000 UPDATE

The Year 2000 ("Y2K") issue concerns the inability of computerized
information systems and non-information systems to accurately calculate, store
or use a date after 1999. This could result in computer system failures or
miscalculations causing disruptions of operations.

In 1997, the Company implemented a corporate-wide Y2K program to
minimize any such disruption caused by the failures of its own internal systems
or those of its business supply chain. In the first phase of the project, the
Company reviewed its inventory of computer hardware and software, and other
devices with embedded microprocessors. The Company also discussed its software
applications and internal operational programs with its current information
systems' vendors. Finally, in this assessment phase, key members of the business
supply chain were contacted and interviewed regarding their awareness of the Y2K
problem and the status of their own Y2K project. The first phase was completed
on schedule during 1998 and all key members of the Company's business supply
chain reported that they were aware of the Y2K problem and were in the process
of readying for the Y2K issue.

In the second phase of the project, all systems found to be Y2K
non-compliant were upgraded, fixed, replaced and tested. The second phase was
also completed on schedule in December 1998. The Company believes that as a
result of this Implementation/Testing phase, its applications and programs will
properly recognize calendar dates beginning in the year 2000. The Company plans
to continue monitoring Y2K communications from its software vendors and
anticipates that some vendors will recommend further patches/upgrades and
testing.

In the third and final phase of the Y2K program, the Company is
surveying its material third-party service providers, such as its banks, payroll
processor, stock transfer agent and telecommunications provider. The purpose of
the survey is to follow-up on the status of their Y2K compliance efforts and
assess what effect their possible non-compliance might have on the Company. In
addition, the Company is discussing with its material vendors the possibility of
any interface difficulties and/or electrical or mechanical problems relating to
Y2K which may affect properties owned or operated by the Company. The Company
plans to complete its assessment of Y2K compliance by such parties by April 30,
1999. Until such time, the Company cannot estimate any potential adverse impact
resulting from the failure of vendors or third-party service providers to
address their Y2K issues; however, to date, no significant Y2K related
conditions have been identified.

Expenditures for assessing the Company's Y2K issues have not been
material because the evaluation has been conducted by its own personnel or by
its vendors in connection with their servicing operations. The Company has
contracted a consultant for $25,000 to assess the methodology of its Y2K
program. The Company plans to remedy any exceptions found during this review
process and deemed as material by the Company by June 30, 1999.

Based on its current information, the Company believes that the risk
posed by any foreseeable Y2K related problem with its internal systems and the
systems at its properties (including both information and non-information
systems) or with its vendors is minimal. Y2K related problems with the Company's
software applications and internal operational programs or with the electrical
or



18

mechanical systems at its properties are unlikely to cause more than minor
disruptions in the Company's operations. The Company believes that the risk
posed by Y2K related problems for certain third-party service providers is
marginally greater, though, based on its current information, the Company does
not believe any such problems would have a material effect on its operations.
Any Y2K related problems at these third-party service providers could delay the
processing of financial transactions or payroll and could disrupt the Company's
internal and external communications.

While the Company believes that it will be Y2K capable by December 31,
1999, there can be no assurance that the Company has been or will be successful
in identifying and assessing Y2K issues, or that, to the extent identified, the
Company's efforts to resolve such issues will be effective such that Y2K issues
will not have a material adverse effect on the Company's business, financial
condition, or results of operation.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). This Statement establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. This statement will be adopted
effective January 1, 2000. The Company has not yet determined the impact of SFAS
133 on the earnings and financial position of the Company.

OTHER

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 1998, 1997
and 1996:

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company's principle market risk exposure is interest rate risk.
The Company's exposure to market risk for changes in interest rates relates
primarily to refinancing long-term fixed rate obligations, the opportunity cost
of fixed rate obligations in a falling interest rate environment and its
variable rate line of credit. The Company primarily enters into debt obligations
to support general corporate purposes including acquisitions, capital
improvements and working capital needs. The Company has used interest rate hedge
agreements to hedge against rising interest rates in anticipation of refinancing
or new debt issuance. Information relating to quantitative and qualitative
disclosure about market risk as it relates to hedging transactions is described
in Note 5 "Debt" to the Company's Consolidated Financial Statements and is
incorporated herein by reference.

The table below presents principal, interest and related weighted
average interest rates by year of maturity (in thousands):

REPORT OF INDEPENDENT ACCOUNTANTS


To the Partners of Sun Communities
Operating Limited Partnership:

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, partners' capital and of cash flows present
fairly, in all material respects, the financial position of Sun Communities
Operating Limited Partnership (the "Company") at December 31, 1998 and December
31, 1997, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles. In addition, in our opinion, the
financial statement schedule listed in the index appearing under Item 14(a)(1)
presents fairly, in all material respects, the information set forth therein
when read in conjunction with the related consolidated financial statements.
These financial statements and financial statement schedule are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

1. BASIS OF PRESENTATION:

Sun Communities Operating Limited Partnership (the "Company") owns and
operates or finances manufactured housing community properties. Sun
Communities, Inc. ("Sun"), a self-administered and self-managed Real Estate
Investment Trust with no independent operations of its own, is the sole
general partner of the Company. As general partner, Sun has unilateral
control and complete responsibility for management of the Company. Pursuant
to the terms of the operating partnership agreement, the Company is
required to reimburse Sun for the net expenses incurred by Sun. Amounts
paid on behalf of Sun by the Company are reflected in the statement of
income as general and administrative expenses. The balance sheet of Sun as
of December 31, 1998 is identical to the accompanying Company balance
sheet, except as follows:

2. SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES:

A. BUSINESS: The Company and its subsidiaries own and operate or finance
104 manufactured housing communities located in 15 states concentrated
principally in the Midwest and Southeast comprising approximately
37,500 developed sites and approximately 6,900 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.

SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP

DECEMBER 31, 1998, 1997 AND 1996

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 an annual
cumulative 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,
1998 stock price of $34.81, the 1.325 million POP Units would have
converted into 1.2 million OP Units.

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. INVESTMENTS IN AND ADVANCES TO AFFILIATES: Sun Home Services ("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.

Bingham Financial Services, Corp. ("BFSC") is a specialty finance
company whose primary business activities include the financing of
manufactured homes and all aspects of commercial real estate mortgage
banking, including originating, underwriting, placing, securitizing and
servicing commercial real estate loans. The Company owns 25,000 shares
of the common stock of BFSC (less than 2% of the issued and outstanding
shares of common stock of BFSC) and the Company owns warrants to
purchase 680,000 shares of common stock of BFSC exercisable at prices
ranging from $10 to $14 per share from 2001 through 2018. The market
price of BFSC stock at December 31, 1998 was $14.50. Interest earned on
advances to BFSC is included in income from affiliates.

F. 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES, CONTINUED:

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

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

I. 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.

J. RECLASSIFICATIONS: Certain 1997 and 1996 amounts have been reclassified
to conform with the 1998 financial statement presentation. Such
reclassifications have no effect on operations as originally presented.

Land improvements and buildings consist primarily of infrastructure, roads,
landscaping, and clubhouses, maintenance buildings and amenities. Included
in rental property at December 31, 1998 and 1997 are net carrying amounts
related to capitalized leases of $29.8 million and $18.4 million,
respectively.

During 1998, the Company acquired 10 manufactured housing communities
comprising 2,100 developed sites and 1,000 sites suitable for development
for $65.5 million and 8 development communities comprising 3,650 sites for
$20.1 million. During 1997, the Company acquired 12 manufactured housing
communities comprising 4,250 developed sites and 425 sites suitable for
development for $69.8 million. 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 a prior year acquisition, the Company is obligated to
issue $11.1 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.

SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED

5. DEBT CONTINUED:

The Company has a $100 million unsecured line of credit at LIBOR plus .90%
maturing in November, 1999, of which $74 million was available at December
31, 1998. The average interest rate of outstanding borrowings at December
31, 1998 was 6.30%.

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, 1998, the Company has Treasury Rate Locks for a total
notional amount of $52.8 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 1999 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, 1998, the maturities of debt, excluding the line of credit,
during the next five years were approximately as follows: 1999 - $1.7
million; 2000 - $1.8 million; 2001 - $76.2 million; 2002 $17.1 million; and
2003 - $86.0 million.

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:



1998 1997 1996
--------- --------- ---------


Estimated fair value per share/unit of options granted during year......................$ 2.43 $ 2.82 $ 1.94

Assumptions:
Annualized dividend yield .......................................................... 7.0% 7.1% 6.9%
Common stock/partnership interest price volatility ................................. 15.9% 15.6% 15.1%
Risk-free rate of return ........................................................... 5.4% 6.7% 6.2%
Expected option term (in years) .................................................... 4 7 8



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 $29.3
million, $25.0 million and $13.2 million and net income per OP Unit of $1.53,
$1.36 and $.84 in 1998, 1997 and 1996 respectively.


7. PARTNERS CAPITAL:

In June 1998, the Company's general partner issued stock awards of 165,00
restricted shares to executive officers which are being amortized over
their 10 year vesting period.

In December 1998, the Company and its general partner issued common stock
and OP units aggregating $25.5 million to directors, employees and
consultants. The purchase was financed by personal bank loans guaranteed by
the Company.


8. EARNINGS PER OP UNIT (AMOUNTS IN THOUSANDS):




1998 1997 1996

Earnings used for basic and diluted earnings per
OP Unit computation $29,549 $25,422 $13,387

Total shares used for diluted earnings per OP Unit
computation 19,276 18,631 15,733

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 1998, 1997 and 1996.
