The accompanying consolidated financial statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. Certain reclassifications have been made to prior periods’ financial statements in order to conform to current period presentation. The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the SEC on February 20, 2014 (the “2013 Annual Report”).

Real Estate Acquisitions and Dispositions

Acquisitions

In June 2014, we acquired Lake Rudolph Campground and Recreational Vehicle Resort ("Lake Rudolph"), a recreational vehicle ("RV") community with 503 sites located in Santa Claus, Indiana.

In April 2014, we acquired Saco/Old Orchard Beach RV Resort ("Saco"), a community with 127 sites located in Saco, Maine.

In February 2014, we acquired Driftwood Camping Resort ("Driftwood"), an RV community with 698 sites and expansion potential of approximately 30 sites located in Clermont, New Jersey, and Seashore Campsites RV and Campground ("Seashore"), an RV community with 685 sites located in Cape May, New Jersey.

In January 2014, we acquired Castaways RV Resort & Campground ("Castaways"), an RV community with 369 sites and expansion potential of approximately 25 sites located in Worcester County, Maryland, and Wine Country RV Resort ("Wine Country"), an RV community with 166 sites and expansion potential of approximately 34 sites located in Paso Robles, California.

The following tables summarize the amounts of the assets acquired and liabilities assumed at the acquisition dates and the consideration paid for acquisitions completed in 2014 (in thousands):

The purchase price allocations for Wine Country, Castaways, Seashore, Driftwood, Saco and Lake Rudolph are preliminary and may be adjusted as final costs and final valuations are determined.

The amount of revenue and net income included in the consolidated statements of operations for the three and six months ended June 30, 2014 for all acquisitions described above is set forth in the following table (in thousands):



	Three Months Ended June 30, 2014		Six Months Ended June 30, 2014
	(unaudited)
Revenue	$	5,026	$	6,079
Net income	$	2,866	$	3,225

2. Real Estate Acquisitions and Dispositions, continued

The following unaudited pro forma financial information presents the results of our operations for the three and six months ended June 30, 2014 and 2013 as if the properties were acquired on January 1, 2013. The unaudited pro forma results reflect certain adjustments for items that are not expected to have a continuing impact, such as adjustments for transaction costs incurred, management fees and purchase accounting. The information presented below has been prepared for comparative purposes only and does not purport to be indicative of either future results of operations or the results of operations that would have actually occurred had the acquisitions been consummated on January 1, 2013 (in thousands, except per-share data).



	Three Months Ended June 30,				Six Months Ended June 30,
	(unaudited)
	2014		2013		2014		2013
Total revenues	$	116,960	$	103,338	$	229,862	$	209,438
Net income attributable to Sun Communities, Inc. common stockholders	$	5,730	$	2,098	$	15,534	$	9,844
Net income per share attributable to Sun Communities, Inc. common stockholders - basic	$	0.14	$	0.06	$	0.40	$	0.30
Net income per share attributable to Sun Communities, Inc. common stockholders - diluted	$	0.14	$	0.06	$	0.40	$	0.30

Transaction costs of approximately $1.1 million and $1.1 million and $1.9 million and $2.2 million have been incurred for the three and six months ended June 30, 2014 and 2013, respectively, and are presented as “Transaction costs” in our consolidated statements of operations.

Dispositions

In June 2014, we closed on the sale of four manufactured housing ("MH") communities: Continental Estates, Davison East, Countryside Village and Desert View Village. During the first quarter of 2014, the Company chose to early adopt Accounting Standards Update ("ASU") 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"). Pursuant to ASU 2014-08, the disposal of the communities does not qualify for presentation as discontinued operations, as the sale does not have a major impact on our operations and financial results and does not represent a strategic shift. Additionally, the communities are not considered individually significant components that do not qualify for presentation as discontinued operations. A gain of $0.9 million is recorded in "Gain on disposition of properties, net" in our consolidated statement of operations.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Transfers Of Financial Assets

Transfers and Servicing [Abstract]

Transfers Of Financial Assets

Transfers of Financial Assets

We completed various transactions with an unrelated entity involving our notes receivable under which we received cash proceeds in exchange for relinquishing our right, title and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of note default, and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note. The percentage used to determine the repurchase price of the outstanding principal balance on the installment note is based on the number of payments made on the note. In general, the repurchase price is determined as follows:



Number of Payments	Repurchase %
Less than or equal to 15	100	%
Greater than 15 but less than 64	90	%
Equal to or greater than 64 but less than 120	65	%
120 or more	50	%

The transferred assets have been classified as collateralized receivables in Notes and Other Receivables (see Note 5), and the cash proceeds received from these transactions have been classified as a secured borrowing in Debt (see Note 9) within the consolidated balance sheets. The balance of the collateralized receivables was $114.9 million (net of allowance of $0.8 million) and $109.8 million (net of allowance of $0.7 million) as of June 30, 2014 and December 31, 2013, respectively. The outstanding balance on the secured borrowing was $115.7 million and $110.5 million as of June 30, 2014 and December 31, 2013, respectively.

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):



	Six Months Ended
	June 30, 2014
Beginning balance	$	110,510
Financed sales of manufactured homes	15,664
Principal payments and payoffs from our customers	(5,148		)
Principal reduction from repurchased homes	(5,366		)
Total activity	5,150
Ending balance	$	115,660

The collateralized receivables earn interest income, and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $2.9 million and $2.6 million and $5.6 million and $5.0 million for the three and six months ended June 30, 2014 and 2013, respectively.

- Definition

The entire disclosure for a transferor's continuing involvement in financial assets that it has transferred in a securitization or asset-backed financing arrangement, the nature of any restrictions on assets reported by an entity in its statement of financial position that relate to a transferred financial asset (including the carrying amounts of such assets), how servicing assets and servicing liabilities are reported, and (for securitization or asset-backed financing arrangements accounted for as sales) when a transferor has continuing involvement with the transferred financial assets and transfers of financial assets accounted for as secured borrowings, how the transfer of financial assets affects an entity's financial position, financial performance, and cash flows.

Origen Financial Services, LLC (“OFS LLC”)

At June 30, 2014 and 2013, we had a 22.9% ownership interest in OFS LLC, an entity formed to originate manufactured housing installment contracts. We have suspended equity accounting as the carrying value of our investment is zero.

Origen Financial, Inc. (“Origen”)

Through Sun OFI, LLC, a taxable REIT subsidiary, we own 5,000,000 shares of common stock of Origen which approximates an ownership interest of 19%. Although it is no longer originating or servicing loans, Origen continues to manage an existing portfolio of manufactured home loans and asset backed securities. We have suspended equity accounting for this investment as the carrying value of our investment is zero. We do, however, receive income from distributions on our shares of Origen common stock. Per Origen's amended earnings release dated June 3, 2014, the distribution payment represented a return of capital. Our investment in Origen had a market value of approximately $7.8 million based on a quoted market closing price of $1.56 per share from the OTC Pink Marketplace as of June 30, 2014.

Variable interest entities ("VIEs") that are consolidated include Rudgate Village SPE, LLC, Rudgate Clinton SPE, LLC and Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”). We concluded that the Rudgate Borrowers qualify as VIEs as we are the primary beneficiary and hold a controlling financial interest in these entities due to our power to direct the activities that most significantly impact the economic performance of the entities, as well as our obligation to absorb the most significant losses and our rights to receive significant benefits from these entities. As such, the transactions and accounts of these VIEs are included in the accompanying consolidated financial statements.

Collateralized Term Loans

In January 2014, we and four of our subsidiaries obtained four mortgage loans (each, an “Individual Loan” and, together, the “Loan”) in the aggregate amount of $99.0 million from The Northwestern Mutual Life Insurance Company (“NM”) pursuant to a Master Loan Agreement with NM. Each Individual Loan accrues interest at a rate of 4.20% and matures on February 13, 2026. We and each of the four borrowers have guaranteed the Loan. The proceeds of the Loan were used to repay a portion of our senior secured line of credit.

9. Debt and Lines of Credit, continued

The collateralized term loans totaling $1.1 billion as of June 30, 2014, are secured by 99 properties comprised of 40,220 sites representing approximately $701.3 million of net book value.

Aspen Preferred OP Units

The Aspen preferred OP units issued by the Operating Partnership are convertible into 526,212 shares of the Company's common stock based on a conversion price of $68 per share with a redemption date of January 1, 2024. The current preferred rate is 6.5%.

Secured Borrowing

See Note 4, "Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Mortgage Notes

The mortgage notes totaling $141.3 million as of June 30, 2014, are collateralized by 18 properties comprised of 7,915 sites representing approximately $241.8 million of net book value.

Lines of Credit

We have a senior secured revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $350.0 million (the "Facility"). The Facility has a four year term ending May 15, 2017, which can be extended for one additional year at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $250.0 million. The Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which can range from 1.65% to 2.90%. Based on our calculation of the leverage ratio as of June 30, 2014, the margin was 1.65%. At June 30, 2014 and December 31, 2013, we had approximately $31.9 million and $178.1 million, respectively, outstanding under the Facility. At June 30, 2014 and December 31, 2013, approximately $2.0 million and $2.7 million, respectively, of availability was used to back standby letters of credit.

The Facility is secured by a first priority lien on all of our equity interests in each entity that owns all or a portion of the properties constituting the borrowing base and collateral assignments of our senior and junior debt positions in certain borrowing base properties.

We also have a $20.0 million secured line of credit agreement collateralized by a portion of our rental home portfolio. The net book value of the rental homes pledged as security for the loan must meet or exceed 200% of the outstanding loan balance. The terms of the agreement require interest only payments for the first five years, with the remainder of the term being amortized based on a 10 year term. The interest rate is the prime rate as published in the Wall Street Journal adjusted the first day of each calendar month plus 200 basis points with a minimum rate of 5.5%. At both June 30, 2014 and December 31, 2013, the effective interest rate was 5.5%, and there was no amount outstanding.

Lastly, we have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us a twelve month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in the Wall Street Journal on the first business day of each month or 6.0%. At June 30, 2014, the effective interest rate was 7.0%. The outstanding balance was $6.6 million and $3.3 million at June 30, 2014 and December 31, 2013, respectively.

Covenants

The most restrictive of our debt agreements place limitations on secured borrowings and contain minimum fixed charge coverage, leverage, distribution and net worth requirements. At June 30, 2014, we were in compliance with all covenants.

Stockholders' Equity Note [Abstract]
Equity Transactions	Equity Transactions In March 2014, we closed an underwritten registered public offering of 4,200,000 shares of common stock at a price of $44.45 per share, and in April 2014, the underwriters exercised their option to purchase an additional 630,000 shares of common stock at a price of $44.45 less the declared dividend of $0.65 per share. Net proceeds from the offering were $214.0 million after deducting underwriting discounts and the expenses related to the offering. We used the net proceeds of the offering to repay borrowings outstanding under the Facility, for acquisitions of properties and for working capital and general corporate purposes. In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock. We have 400,000 common shares remaining in the repurchase program. No common shares were repurchased during the six months ended June 30, 2014 or 2013. There is no expiration date specified for the buyback program. Common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time. During the six months ended June 30, 2014 and 2013, there were no common OP units converted to shares of common stock. Subject to certain limitations, Series A-1 preferred OP unit holders may convert their Series A-1 preferred OP units to shares of our common stock at any time. During the six months ended June 30, 2014, holders of Series A-1 preferred OP units converted 17,075 units to 41,645 shares of common stock. No such units were converted during the six months ended June 30, 2013. Cash distributions of $0.65 per share were declared for the quarter ended June 30, 2014. On July 18, 2014, cash payments of approximately $28.1 million for aggregate distributions were made to common stockholders, common OP unitholders and restricted stockholders of record as of June 30, 2014. In addition, cash distributions of $0.4453 per share were declared on the Company's Series A cumulative redeemable preferred stock. On July 15, 2014, cash payments of approximately $1.5 million for aggregate distributions were made to Series A cumulative redeemable preferred stockholders of record as of July 1, 2014.

Share-based Compensation [Abstract]
Share-Based Compensation	Share-Based Compensation In June 2014, we granted 20,250 shares of restricted stock to employees under our Sun Communities Inc. Equity Incentive Plan ("2009 Equity Plan"). The restricted shares had a fair value of $49.84 per share and will vest as follows: June 30, 2017: 35%; June 30, 2018: 35%; June 30, 2019: 20%; June 30, 2020: 5%; June 30, 2021: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued. In June 2014, we also granted 50,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The restricted shares had a fair value of $49.84 per share and will vest as follows: June 30, 2018: 20%; June 30, 2019: 30%; June 30, 2020: 35%; June 30, 2021: 10%; June 30, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued. In February 2014, we granted 16,000 shares of restricted stock to an executive officer and a key employee under our 2009 Equity Plan. The restricted shares had a fair value of $48.01 per share and will vest as follows: February 12, 2018: 20%; February 12, 2019: 30%; February 12, 2020: 35%; February 12, 2021: 10%; February 12, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued. In February 2014, we granted 14,000 shares of restricted stock to our directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 12, 2017, and had a fair value of $48.01 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued. During the six months ended June 30, 2014, 4,904 shares of common stock were issued in connection with the exercise of stock options and the net proceeds received were $0.1 million. The vesting requirements for 18,045 restricted shares granted to our employees were satisfied during the six months ended June 30, 2014.

Segment Reporting [Abstract]

Segment Reporting

We group our operating segments into reportable segments that provide similar products and services. Each operating segment has discrete financial information evaluated regularly by the Company's chief operating decision maker in evaluating and assessing performance. We have two reportable segments: (i) Real Property Operations and (ii) Home Sales and Rentals. The Real Property Operations segment owns, operates, and develops MH communities and RV communities and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities.

Transactions between our segments are eliminated in consolidation. Transient RV revenue is included in Real Property Operations’ revenues and is expected to approximate $31.7 million annually. This transient revenue was recognized 25.2% and 18.2% in the first and second quarters, respectively, and is expected to be recognized 43.2% in the third quarter and 13.4% in the fourth quarter of 2014. In 2013, transient revenue was $17.4 million and was recognized 40.0% in the first quarter, 15.0% in the second quarter, 30.0% in the third quarter and 15.0% in the fourth quarter.

A presentation of segment financial information is summarized as follows (amounts in thousands):

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2014
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We have elected to be taxed as a real estate investment trust (“REIT”) as defined under Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least ninety-five percent (95%) of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders. Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended June 30, 2014. As a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on the ordinary taxable income we distribute to our stockholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain state and local income taxes and to U.S. federal income and excise taxes on our undistributed income. SHS, our taxable REIT subsidiary, is subject to U.S. federal income taxes. Our deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards and depreciation. A federal deferred tax asset of $1.0 million is included in other assets in our consolidated balance sheets as of June 30, 2014 and December 31, 2013. We had no unrecognized tax benefits as of June 30, 2014 and 2013. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2014. We classify certain state taxes as income taxes for financial reporting purposes. We record Texas Margin Tax as income tax in our financial statements, and we recorded a provision for state income taxes of approximately $0.1 million for the three and six months ended June 30, 2014 and 2013.

Earnings Per Share [Abstract]

Earnings Per Share

We have outstanding stock options and unvested restricted shares, and our Operating Partnership has outstanding common OP units, convertible A-1 preferred OP units, convertible A-3 preferred OP units and Aspen preferred OP Units, which, if converted or exercised, will impact dilution.

Computations of basic and diluted earnings per share from continuing operations were as follows (in thousands, except per share data):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate swaps and caps are used to accomplish this objective. We require hedging derivative instruments to be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract. We do not enter into derivative instruments for speculative purposes.

The following table provides the terms of our interest rate derivative contracts that were in effect as of June 30, 2014:

In January 2014, our interest rate swap agreement with a notional amount of $20.0 million expired. We did not enter into a new interest rate swap agreement.

In accordance with ASC Topic 815, Derivatives and Hedging, we have recorded the fair value of our derivative instruments designated as cash flow hedges on the balance sheet. See Note 16 for information on the determination of fair value for the derivative instruments. The following table summarizes the fair value of derivative instruments included in our consolidated balance sheets as of June 30, 2014 and December 31, 2013 (in thousands):

	Balance Sheet Location	Fair Value				Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments		June 30, 2014		December 31, 2013			June 30, 2014		December 31, 2013
Interest rate swaps and cap agreement	Other assets	$	—	$	—	Other liabilities	$	—	$	97
Total derivatives designated as hedging instruments		$	—	$	—		$	—	$	97

These valuation adjustments will only be realized under certain situations. For example, if we terminate contracts prior to maturity or if derivatives fail to qualify for hedge accounting, we would need to amortize amounts currently included in accumulated other comprehensive income into interest expense over the terms of the derivative contracts. We did not terminate our swap prior to maturity, and it did not fail to qualify for hedge accounting; therefore, the net of valuation adjustments through the maturity date approximated zero.

Our hedges were highly effective and had minimal effect on income. The following tables summarize the impact of derivative instruments for the three and six months ended June 30, 2014 and 2013 as recorded in the consolidated statements of operations (in thousands):



Derivatives in Cash Flow Hedging	Amount of Gain or (Loss) Recognized in OCI (Effective Portion)				Location of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)

Interest rate swaps and cap agreement	$	97	$	177	Interest expense	$	—	$	—
Total	$	97	$	177	Total	$	—	$	—

Our financial derivative instruments are designated and qualify as cash flow hedges and the effective portion of the gain or loss on such hedges are reported as a component of accumulated other comprehensive income in our consolidated balance sheets.

To the extent that the hedging relationship is not effective or does not qualify as a cash flow hedge, the ineffective portion is recorded in interest expense. Hedges that received designated hedge accounting treatment are evaluated for effectiveness at the time that they are designated as well as through the hedging period. No gain or loss was recognized in the consolidated financial

statements related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedge during the three months ended June 30, 2014 or 2013.

Certain of our derivative instruments contain provisions that require us to provide ongoing collateralization on derivative instruments in a liability position. As of December 31, 2013, we had collateral deposits recorded in other assets of approximately $0.7 million. As of June 30, 2014, we had no such deposits recorded.

- Definition

The entire disclosure for derivative instruments and hedging activities including, but not limited to, risk management strategies, non-hedging derivative instruments, assets, liabilities, revenue and expenses, and methodologies and assumptions used in determining the amounts.

Fair Value of Financial Instruments

6 Months Ended

Jun. 30, 2014

Fair Value Disclosures [Abstract]

Fair Value Of Financial Instruments

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories:

Level 1—Quoted unadjusted prices for identical instruments in active markets.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all observable inputs and significant value drivers are observable in active markets.

Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by us.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value.

Derivative Instruments

The derivative instruments held by us are interest rate swap and cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all observable inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair values of derivative instruments on a recurring basis (Level 2). See Note 15 for Derivative Instruments.

Installment Notes on Manufactured Homes

The net carrying value of the installment notes on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). See Note 5 for Installment Notes.

16. Fair Value of Financial Instruments, continued

Long Term Debt and Lines of Credit

The fair value of long term debt (excluding the secured borrowing) is based on the estimates of management and on rates currently quoted and rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). See Note 9 for Long-Term Debt and Lines of Credit.

Collateralized Receivables and Secured Borrowing

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing in the consolidated balance sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). See Note 4 for Collateralized Receivables and Secured Borrowing.

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

The table below sets forth our financial assets and liabilities that required disclosure of their fair values on a recurring basis and presents the carrying values and fair values as of June 30, 2014 and December 31, 2013 that were measured using the valuation techniques described above. The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.



	June 30, 2014				December 31, 2013
Financial assets	Carrying Value		Fair Value		Carrying Value		Fair Value
Installment notes on manufactured homes, net	$	23,134	$	23,134	$	25,471	$	25,471
Collateralized receivables, net	$	114,871	$	114,871	$	109,821	$	109,821
Financial liabilities
Derivative instruments	$	—	$	—	$	97	$	97
Debt (excluding secured borrowing)	$	1,291,642	$	1,328,406	$	1,200,927	$	1,211,821
Secured borrowing	$	115,660	$	115,660	$	110,510	$	110,510
Lines of credit	$	38,461	$	38,461	$	181,383	$	181,383

The derivative instruments are the only financial liabilities that were required to be carried at fair value in the consolidated balance sheets for the periods indicated, and we have no financial assets that are required to be carried at fair value.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Recent Accounting Pronouncements	6 Months Ended
Recent Accounting Pronouncements	Jun. 30, 2014
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2014-09, (“ASU 2014-09”), “Revenue from Contracts with Customers” as a new Topic, Accounting Standards Codification ("ASC") Topic 606. The objective of ASU 2014-19 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new standard, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early adoption is not permitted. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on the consolidated financial statements nor decided upon the method of adoption. In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"). ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation by requiring only those disposals of a component or group of components that represent a strategic shift or that will have a major effect on the Company’s operational and financial results and also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance does not change the presentation 17. Recent Accounting Pronouncements, continued requirements for discontinued operations in the statement where net income is presented. ASU 2014-08 also requires the reclassification of assets and liabilities of a discontinued operation in the statement of financial position for all prior periods presented. The standard expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not meet the definition of a discontinued operation, an entity's continuing involvement with a discontinued operation following the disposal date and retained equity method investments in a discontinued operation. ASU 2014-08 is effective for annual periods beginning on or after December 15, 2014 and interim periods within annual periods beginning on or after December 15, 2015. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. The Company has chosen to early adopt this pronouncement and has applied the guidance to recent applicable disposals (see Note 2).

- Definition

Tabular disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

Commitments And Contingencies	6 Months Ended
Commitments And Contingencies	Jun. 30, 2014
Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	Commitments and Contingencies On June 4, 2010, we settled all of the claims arising out of the litigation filed in 2004 by TJ Holdings, LLC in the Superior Court of Guilford County, North Carolina and the associated arbitration proceeding commenced by TJ Holdings in Southfield, Michigan. Under the terms of the settlement agreement, in which neither party admitted any liability whatsoever, we paid TJ Holdings $360,000. In addition, pursuant to this settlement, TJ Holdings’ percentage ownership interest in Sun/Forest, LLC will be increased on a one time basis, in the event of a sale or refinance of all of the SunChamp Properties, to between 9.03% and 28.99% depending on our average closing stock price as reported by the NYSE during the 30 days preceding the sale or refinance of all the SunChamp Properties. Once this percentage ownership interest has been adjusted, there will be no further adjustments from subsequent sales or refinances of the SunChamp Properties. The likelihood of a sale or refinancing of all of the SunChamp properties is not probable as these properties continue to see growth potential nor do we have a need to refinance all of the properties, so we do not expect it to have a material adverse impact on our results of operations or financial condition. We are involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events We have evaluated our financial statements for subsequent events through the date that this Form 10-Q was issued. Share-based Compensation In July 2014, the Company and Gary A. Shiffman (the Company's Chairman and Chief Executive Officer) entered into an Amended and Restated Restricted Stock Award Agreement, which amended and restated in its entirety the Restricted Stock Award Agreement dated June 20, 2013 between the Company and Mr. Shiffman. Under the original stock award agreement, the Company granted Mr. Shiffman 250,000 restricted shares of the Company's common stock, of which 175,000 restricted shares were awarded in respect of the performance of Mr. Shiffman and the Company over the prior three years and 75,000 restricted shares were awarded to induce Mr. Shiffman to execute a new five-year employment agreement. All of these restricted shares were scheduled to vest over time through June 2020. The restated stock award agreement amended the vesting schedule of the restricted shares, of which 100,000 restricted shares are now subject to performance vesting and the remaining 150,000 shares will vest over time through June 2020. The Company filed a Form 8-K on July 15, 2014 regarding the details of this event. Disposition of Property In July 2014, the Company sold a manufactured housing community located in Michigan for a total of $0.5 million. Debt In July 2014, the Company entered into a 10 year loan agreement for $26.9 million at a rate of 4.57% which is collateralized by two RV communities. The proceeds were used to pay down the Company’s line of credit.
