FOR IMMEDIATE RELEASE


                   SUN COMMUNITIES, INC. REPORTS 2004 RESULTS


SOUTHFIELD, MI, FEBRUARY 24, 2005 - SUN COMMUNITIES, INC. (NYSE: SUI), a real
estate investment trust (REIT) that owns and operates manufactured housing
communities, today reported fourth quarter and year ended December 31, 2004
results.

Income from rental property increased 5.5 percent to $167.8 million for the year
ended December 31, 2004 from $159.1 million for the year ended December 31,
2003. Net loss for the year ended December 31, 2004 was $(40.5) million or
$(2.21) per common share compared to net income of $23.7 million or $1.29 per
diluted common share during 2003. Funds from operations (FFO)(1) was $(3.3)
million, or $(0.16) per share/OP Unit for the year ended December 31, 2004; a
decrease from FFO of $65.5 million, or $3.14 per diluted share/OP Unit for the
year ended December 31, 2003. The decreases in net income and FFO are due
largely to charges of $51.6 million for prepayment costs, fees and related
expenses and $5.6 million of deferred financing costs associated with the
repurchase of $345 million of unsecured debt in the second quarter of 2004 and
the associated recapitalization of the Company. Excluding these costs, FFO for
2004 would have been $53.9 million or $2.57 per diluted share/OP unit and net
income would have been $16.7 million or $0.91 cents per diluted common share.

During the fourth quarter ended December 31, 2004, income from rental property
increased 9.6 percent to $43.5 million, compared with $39.7 million in the
fourth quarter of 2003. Income from continuing operations for the fourth quarter
of 2004 was $1.3 million or $0.07 per diluted common share, compared with loss
of $(2.6) million, or $(0.14) per diluted common share for the same period in
2003. Funds from continuing operations decreased from $11.7 million, or $0.55
per diluted share/OP Unit in the fourth quarter 2003 to $10.3 million, or $0.50
per diluted share/OP Unit in the fourth quarter 2004.

For 108 communities owned throughout both years, total revenues increased 4.0
percent for the year ended December 31, 2004 and expenses increased 3.4 percent,
resulting in an increase in net operating income(2) of 4.25 percent. Same
property occupancy in the manufactured housing sites decreased from 88.4 percent
at September 30, 2004 to 87.4 percent at December 31, 2004.

As previously noted the Company completed a significant restructuring of its
capital and operating debt during 2004. Secured debt financings of $734 million
with average terms approximating 10 years and weighted average interest rates of
approximately 5.0% were concluded, as well as the successful negotiation of a
new $115 million revolving line of credit at LIBOR + 1.75%. Proceeds from the
secured financings were used to retire existing debt, acquire communities, and
repurchase the Company's stock. The Company has also provided the required
notice to retire $50 million of 8.875% perpetual preferred partnership units
during the first quarter of 2005 and is authorized to repurchase up to 1 million
additional shares of its stock.

During 2004 the Company acquired nine manufactured housing communities
comprising approximately 2950 developed and 570 undeveloped sites. The aggregate
purchase price was $120.4 million and included the assumption of approximately
$34.3 million in debt. Three of the communities are in northeast Atlanta, four
are located in Michigan and the remaining properties are located in Colorado and
Texas.

"While we looked for a year of industry transition, manufactured housing
conditions never reversed, but did seem to stabilize during 2004. Home
shipments, repossessions, finance company recoveries and delinquencies ended the
year at similar or slightly improved levels over 2003. The first half of the
year reflected strongly improving occupancy statistics in the Company's
portfolio, the second half suffered from another surge of repossessed homes,
depressing overall occupancy. Performance of the same site portfolio was one
bright spot in an otherwise difficult manufactured home environment." said Gary
A. Shiffman, Chief Executive Officer.

"This past year marks many significant accomplishments that position the Company
to regain positive year over year FFO growth. Putting both the refinancing and
implementation of an entirely new software system in both accounting and
operations behind us, management is focused on its leasing and sales efforts, as
well as acquisition opportunities. While it remains early, the overall portfolio
has had a net gain of 61 sites so far this year." Shiffman added.

Through February 19, 2005, the Company has added 61 net leased sites which
represents five weeks of positive performance after losses of 42 net sites in
the first two weeks of the year. This leasing rate, if maintained, will result
in 445 net leased sites which is the plan for 2005. For the first fifty days of
the year, the Company has averaged leasing gains and losses of 7.8 and 6.6 per
day, respectively.

The Company stands by its previously issued earnings guidance.

Sun Communities currently owns and operates a portfolio of 136 communities
mainly in the Midwest and Southeast United States. The Company's properties are
comprised of over 46,800 developed sites and approximately 7,300 additional
sites available for development.

(1) Funds from operations ("FFO") is defined by the National Association of Real
    Estate Investment Trusts ("NAREIT") as net income (computed in accordance
    with generally accepted accounting principles), excluding gains (or losses)
    from sales of depreciable operating property, plus real estate-related
    depreciation and amortization, and after adjustments for unconsolidated
    partnerships and joint ventures. FFO is a non-GAAP financial measure that
    management believes is a useful supplemental measure of the Company's
    operating performance. Management generally considers FFO to be a useful
    measure for reviewing comparative operating and financial performance
    because, by excluding gains and losses related to sales of previously
    depreciated operating real estate assets and excluding real estate asset
    depreciation and amortization (which can vary among owners of identical
    assets in similar condition based on historical cost accounting and useful
    life estimates), FFO provides a performance measure that, when compared year
    over year, reflects the impact to operations from trends in occupancy rates,
    rental rates and operating costs, providing perspective not readily apparent
    from net income. Management believes that the use of FFO has been beneficial
    in improving the understanding of operating results of REITs among the
    investing public and making comparisons of REIT operating results more
    meaningful.

    Because FFO excludes significant economic components of net income including
    depreciation and amortization, FFO should be used as an adjunct to net
    income and not as an alternative to net income. The principal limitation of
    FFO is that it does not represent cash flow from operations as defined by
    GAAP and is a supplemental measure of performance that does not replace net
    income as a measure of performance or net cash provided by operating
    activities as a measure of liquidity. In addition, FFO is not intended as a
    measure of a REIT's ability to meet debt principal repayments and other cash
    requirements, nor as a measure of working capital. FFO only provides
    investors with an additional performance measure. Other REITS may use
    different methods for calculating FFO and, accordingly, the Company's FFO
    may not be comparable to other REITs.

(2) Investors in and analysts following the real estate industry utilize net
    operating income ("NOI") as a supplemental performance measure. NOI is
    derived from revenues (determined in accordance with GAAP) minus property
    operating expenses and real estate taxes (determined in accordance with
    GAAP). NOI does not represent cash generated from operating activities in
    accordance with GAAP and should not be considered to be an alternative to
    net income (determined in accordance with GAAP) as an indication of the
    Company's financial performance or to be an alternative to cash flow from
    operating activities (determined in accordance with GAAP) as a measure of
    the Company's liquidity; nor is it indicative of funds available for the
    Company's cash needs, including its ability to make cash distributions. The
    Company believes that net income is the most directly comparable GAAP
    measurement to net operating income. Because of the inclusion of items such
    as interest, depreciation and amortization, the use of net income as a
    performance measure is limited as these items may not accurately reflect the
    actual change in market value of a property, in the case of depreciation and
    in the case of interest, may not necessarily be linked to the operating
    performance of a real estate asset, as it is often incurred at a parent
    company level and not at a property level

    The Company believes that net operating income is helpful to investors as a
    measure of operating performance because it is an indicator of the return on
    property investment, and provides a method of comparing property performance
    over time. The Company uses NOI as a key management tool when evaluating
    performance and growth of particular properties and/or groups of properties.
    The principal limitation of NOI is that it excludes depreciation,
    amortization and non-property specific expenses such as general and
    administrative expenses, all of which are significant costs, and therefore,
    NOI is a measure of the operating performance of the properties of the
    Company rather than of the Company overall.

(3) The Company entered into three interest rate swaps and an interest rate cap
    agreement. The valuation adjustment reflects the theoretical noncash profit
    and loss were those hedging transactions terminated at the balance sheet
    date. As the Company has no expectation of terminating the transactions
    prior to maturity, the net of these noncash valuation adjustments will be
    zero at the various maturities. As any imperfection related to hedging
    correlation in these swaps is reflected currently in cash as interest, the
    valuation adjustments reflect volatility that would distort the comparative
    measurement of FFO and on a net basis approximate zero. Accordingly, the
    valuation adjustments are excluded from Funds from Operations. The valuation
    adjustment is included in interest expense.

(4) The Company acquired the equity interest of another investor in SunChamp in
    December 2002. Consideration consisted of a long-term note payable at net
    book value. Although the adjustment for the allocation of the SunChamp
    losses (based on SunChamp as a stand-alone entity) is not reflected in the
    accompanying financial statements, management believes that it is
    appropriate to provide for this adjustment because the Company's payment
    obligations with respect to the note are subordinate in all respects to the
    return of the members' equity (including the gross book value of the
    acquired equity) plus a preferred return. As a result, the losses that are
    allocated to the Company from SunChamp as a stand-alone entity under
    generally accepted accounting principles are effectively reallocated to the
    note for purposes of calculating Funds from Operations. A situation such as
    this is not contemplated in the NAREIT definition of FFO due to the unique
    circumstances of the transaction. Although not comparable to the precise
    NAREIT definition, the Company believes the inclusion of this item in its
    calculation of FFO to be appropriate as noted above.
