During the three months ended March 31, 2022, no mortgage term loans were paid off. During the year ended December 31, 2021, we paid off the following mortgage term loans (in millions, except for statistical information): Period Repayment Amount Fixed Interest Rate Maturity Date Loss on Extinguishment of Debt Three months ended December 31, 2021 $ 11.6 (1) 4.3 % February 1, 2022 $ — (1) Includes two mortgage term loans which matured on February 1, 2022. During the three months ended March 31, 2022 and year ended December 31, 2021, we did not enter into any new mortgage term loans. The mortgage term loans, which total $3.4 billion as of March 31, 2022, are secured by 190 properties comprised of 75,378 sites representing approximately $3.1 billion of net book value. Unsecured Debt Senior Unsecured Notes In October 2021, the Operating Partnership issued $450.0 million of senior unsecured notes with an interest rate of 2.3 percent and a seven ten In June 2021, the Operating Partnership issued $600.0 million of senior unsecured notes with an interest rate of 2.7 percent and a ten-year term, due July 15, 2031 (the "2031 Notes"). Interest on the 2031 Notes is payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2022. The net proceeds from the offering were approximately $592.4 million, after deducting underwriters' discounts and estimated offering expenses. The proceeds were used to pay down borrowings under our Senior Credit Facility. The total outstanding balance of senior unsecured notes was $1.2 billion at March 31, 2022. This balance is recorded in the Unsecured debt line item on the Consolidated Balance Sheets. Line of Credit In June 2021, we entered into a senior credit agreement (the "Credit Agreement") with certain lenders. The Credit Agreement combined and replaced our prior $750.0 million credit facility, which was scheduled to mature on May 21, 2023, (the "A&R Facility"), and the $1.8 billion credit facility between Safe Harbor and certain lenders, which was scheduled to mature on October 11, 2024 (the "Safe Harbor Facility"). The Safe Harbor Facility was terminated in connection with the execution of the Credit Agreement. We repaid all amounts due and outstanding under the Safe Harbor Facility on or prior to the effective date. We recognized a Loss on extinguishment of debt in our Consolidated Statement of Operations related to the termination of the A&R Facility and the Safe Harbor Facility of $0.2 million and $7.9 million, respectively. Pursuant to the Credit Agreement, we may borrow up to $2.0 billion under a revolving loan (the "Senior Credit Facility"). The Senior Credit Facility is available to fund all of the Company's business, including its marina business conducted by Safe Harbor. The Credit Agreement also permits, subject to the satisfaction of certain conditions, additional borrowings (with the consent of the lenders) in an amount not to exceed $1.0 billion with the option to treat all, or a portion, of such additional funds as an incremental term loan. The Senior Credit Facility has a four-year term ending June 14, 2025, and, at our option, the maturity date may be extended for two additional six-month periods, subject to the satisfaction of certain conditions. However, the maturity date with respect to $500.0 million of available borrowing under the Senior Credit Facility is October 11, 2024, which, under the terms of the Credit Agreement, may not be extended. The Senior Credit Facility bears interest at a floating rate based on the Adjusted Eurocurrency Rate or BBSY rate, plus a margin that is determined based on the Company's credit ratings calculated in accordance with the Credit Agreement, which can range from 0.725 percent to 1.4 percent. As of March 31, 2022, the margin based on our credit ratings was 0.85 percent on the Senior Credit Facility. At the lenders' option, the Senior Credit Facility will become immediately due and payable upon an event of default under the Credit Agreement. We had $1.4 billion and $1.0 billion of borrowings on the Senior Credit Facility as of March 31, 2022 and December 31, 2021. Of the total amount borrowed as of March 31, 2022, $1.2 billion is scheduled to mature on June 14, 2025 and $203.0 million is scheduled to mature October 11, 2024. These balances are recorded in Unsecured debt on the Consolidated Balance Sheets. The Senior Credit Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under the Senior Credit Facility, but does reduce the borrowing amount available. We had $2.2 million of outstanding letters of credit at March 31, 2022 and December 31, 2021, respectively. Refer to Note 19, "Subsequent Events," for information regarding the amendment of our Senior Credit Facility completed after March 31, 2022. Bridge Loan Termination On March 31, 2022, we terminated our commitment letter with Citigroup Global Markets, Inc. ("Citigroup"), pursuant to which, Citigroup (on behalf of its affiliates), committed to lend us up to £950.0 million, or approximately $1.2 billion converted at the March 31, 2022 exchange rate (the "Bridge Loan"). As of the date of termination, we did not have any borrowings outstanding under the Bridge Loan. During the three months ended March 31, 2022, we recognized a loss on extinguishment of debt in our Consolidated Statement of Operations of $0.3 million related to the termination of the Bridge Loan. Unsecured Term Loan In October 2019, we assumed a term loan facility, in the amount of $58.0 million in relation to an acquisition. The term loan has a four-year term ending October 29, 2023, and bears interest at a floating rate based on the Eurodollar rate or Prime rate plus a margin ranging from 1.20 percent to 2.05 percent. Effective July 1, 2021, the agreement was amended to release the associated collateral. The amendment extended the term loan facility maturity date to October 29, 2025 and adjusted the interest rate margin to a range from 0.8 percent to 1.6 percent. As of March 31, 2022, the margin was 0.95 percent. The outstanding balance was $28.4 million at March 31, 2022 and $31.6 million at December 31, 2021. These balances are recorded in Unsecured debt and Secured debt on the Consolidated Balance Sheets, respectively. Preferred Equity - Sun NG Resorts - Mandatorily Redeemable In connection with the investment in Sun NG Resorts, $35.3 million of mandatorily redeemable Preferred Equity ("Preferred Equity - Sun NG Resorts") was purchased by unrelated third parties. The Preferred Equity - Sun NG Resorts carries a preferred rate of return of 6.0 percent per annum. The Preferred Equity - Sun NG Resorts has a seven Preferred OP Units - mandatorily redeemable Preferred OP units at March 31, 2022 and December 31, 2021 include $34.7 million of Aspen preferred OP units issued by the Operating Partnership. As of March 31, 2022, these units are convertible indirectly into 393,724 shares of our common stock. In January 2020, we amended the Operating Partnership's partnership agreement. The amendment extended the automatic redemption date and reduced the annual distribution rate for 270,000 of the Aspen preferred OP units (the "Extended Units"). Subject to certain limitations, at any time prior to January 1, 2024 (or prior to January 1, 2034 with respect to the Extended Units), the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the average closing price of our common stock for the preceding ten trading days is $68.00 per share or less, 0.397 common OP units; or (b) if the ten-day average closing price is greater than $68.00 per share, the number of common OP units is determined by dividing (i) the sum of (A) $27.00 plus (B) 25.0 percent of the amount by which the ten-day average closing price exceeds $68.00 per share, by (ii) the ten-day average closing price. The current preferred distribution rate is 3.8 percent on the Extended Units and 6.5 percent on all other Aspen preferred OP units. On January 2, 2024 (or January 2, 2034 with respect to the Extended Units), we are required to redeem for cash all Aspen preferred OP units that have not been converted to common OP units. As of March 31, 2022, 270,000 of the Extended Units and 1,013,819 other Aspen preferred units were outstanding. These balances are recorded within the Unsecured debt line item on the Consolidated Balance Sheets. Covenants The mortgage term loans, senior unsecured notes and Senior Credit Facility are subject to various financial and other covenants. The most restrictive covenants are pursuant to (a) the terms of the Senior Credit Facility, which contains a minimum fixed charge coverage ratio, maximum leverage ratio, distribution ratio and variable rate indebtedness and (b) senior unsecured notes, which contain a total debt to total assets, secured debt to total assets, consolidated income available for debt service to debt service and unencumbered total asset value to unsecured debt covenants. At March 31, 2022, we were in compliance with all covenants. In addition, certain of our subsidiary borrowers own properties that secure loans. These subsidiaries are consolidated within our accompanying Consolidated Financial Statements, however, each of these subsidiaries' assets and credit are not available to satisfy our debts and other obligations, and any of our other subsidiaries or any other person or entity.

Time based awards for directors generally vest over three years. Time based awards for key employees and executives generally vest over five years.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting ASC Topic 280, " Segment Reporting " ("ASC 280"), establishes standards for the way the business enterprises report information about operating segments in its financial statements. As described in Note 1, "Basis of Presentation," we analyze our operating results through the following segments: (i) Manufactured home ("MH") communities, (ii) Recreational vehicle ("RV") resorts and (iii) Marina. The MH segment owns, operates, develops, or has an interest in, a portfolio of MH communities throughout the U.S. and the UK, and is in the business of acquiring, operating and developing ground up MH communities to provide affordable housing solutions to residents. The MH segment also provides manufactured home sales and leasing services to tenants and prospective tenants of our communities. The RV segment owns, operates, develops, or has an interest in, a portfolio of RV resorts and is in the business of acquiring, operating and developing ground up RV resorts throughout the U.S. and in Canada. It also provides leasing services for vacation rentals within the RV resorts. The Marina segment owns, operates, and develops marinas, and is in the business of acquiring and operating marinas throughout the U.S., with the majority of such marinas concentrated in coastal regions, and others located in various inland regions and Puerto Rico.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We have elected to be taxed as a real estate investment trust ("REIT") pursuant to Section 856(c) of the Internal Revenue Code of 1986, as amended ("Code"). In order for us to qualify as a REIT, at least 95 percent of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90 percent of its REIT taxable income (calculated without any deduction for dividends paid and excluding capital gain) to its shareholders and meet other tests. Qualification as a REIT involves the satisfaction of numerous requirements (on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are 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 three months ended March 31, 2022. As a REIT, we generally will not be subject to United States ("U.S.") federal income taxes at the corporate level on the ordinary taxable income we distribute to our shareholders 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. Even if we qualify as a REIT, we may be subject to certain state and local income taxes as well as U.S. federal income and excise taxes on our undistributed income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state and local income taxes. We are also subject to local income taxes in Canada and Puerto Rico due to certain properties located in Canada and one located in Puerto Rico. We do not provide for withholding taxes on our undistributed earnings from our Canadian subsidiaries as they are reinvested and will continue to be reinvested indefinitely outside of the U.S. However, we are subject to Australian withholding taxes on distributions from our investment in Ingenia Communities Group. Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the basis 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 and basis differences between tax and GAAP. Our deferred tax assets that have a full valuation allowance relate to our taxable REIT subsidiaries. Net deferred tax liabilities of $20.7 million for Canadian entities have been recorded in relation to corporate entities and included in Other liabilities in our Consolidated Balance Sheets as of March 31, 2022 and December 31, 2021, respectively. We had no U.S. federal deferred tax liabilities as of March 31, 2022. U.S. federal deferred tax liabilities of $0.1 million have been recorded and included in our Consolidated Balance Sheets as of December 31, 2021. We had no unrecognized tax benefits as of March 31, 2022 and 2021. We do not expect significant changes in tax positions that would result in unrecognized tax benefits within one year of March 31, 2022. For the three months ended March 31, 2022, we recorded a current tax expense for federal, state and Canadian income taxes as well as Australian withholding taxes of $1.3 million. For the three months ended March 31, 2021, we recorded a current tax benefit for federal, state and Canadian income taxes of $0.2 million. For the three months ended March 31, 2021 , we recorded a deferred tax benefit of $0.1 million.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period on a basic and diluted basis. We calculate diluted earnings per share using the more dilutive of the treasury stock method and the two-class method for stock option and restricted common shares, the treasury stock method for forward equity sales and the if converted method for convertible units. From time to time, we enter into forward equity sales agreements, which are discussed in Note 9, "Equity and Temporary Equity." We considered the potential dilution resulting from the forward equity sales agreements on the earnings per share calculations. At inception, the agreements do not have an effect on the computation of basic earnings per share as no shares are delivered unless and until there is a physical settlement. Common shares issued upon the physical settlement of the forward equity sales agreements, weighted for the period these common shares are outstanding, are included in the denominator of basic earnings per share. To determine the dilution resulting from the forward equity sales agreements during the period of time prior to settlement, we calculate the number of weighted-average shares outstanding - diluted. Our potentially dilutive securities include our potential common shares related to our forward equity offerings, our unvested restricted common shares, and our Operating Partnership outstanding common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series C preferred OP units, Series D preferred OP units, Series E preferred OP units, Series F preferred OP units, Series G preferred OP units, Series H preferred OP units, Series I preferred OP units, Series J preferred OP units and Aspen preferred OP Units, which, if converted or exercised, may impact dilution. Diluted earnings per share considers the impact of potentially dilutive securities except when the potential common shares have an antidilutive effect. Our unvested restricted stock common shares contain rights to receive non-forfeitable distributions and participate equally with common stock with respect to distributions issued or declared, and thus, are participating securities, requiring the two-class method of computing earnings per share. In calculating the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average number of shares outstanding during the period. The two-class method determines earnings per share by (1) dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of shares of common stock outstanding for the period; and (2) dividing the sum of distributed earnings allocated to participating securities and undistributed earnings allocated to participating securities by the weighted average number of shares of participating securities for the period. The remaining potentially dilutive common shares do not contain rights to distributions and are included in the computation of diluted earnings per share. Computations of basic and diluted earnings per share were as follows (in millions, except for per share data): Three Months Ended March 31, 2022 March 31, 2021 Numerator Net Income Attributable to Sun Communities, Inc.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments And Hedging Activities	Derivative Financial Instruments Our objective and strategy in using interest rate derivatives is to manage exposure to interest rate movements, thereby minimizing the effect of interest rate changes and the effect they could have on future cash outflows (forecasted interest payments) on a forecasted issuance of long-term debt. Treasury locks are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes. We have designated the treasury lock contracts as cash flow hedges under ASC Topic 815, " Derivatives and Hedging ." The risk being hedged is the interest rate risk related to forecasted transactions and the benchmark interest rate used is the on-the-run 10-year U.S. Treasury rate. As of March 31, 2022, we had four Treasury lock contracts with an aggregate notional amount of $600.0 million that were designated as cash flow hedges of interest rate risk. The unrealized gains or losses on the Treasury lock contracts were recorded in Accumulated other comprehensive income within the Consolidated Balance Sheets, and will be reclassified into earnings in the same period during which the hedged transaction affects earnings. These unrealized gains or losses will be amortized as reduction or increase to Interest expense within the Consolidated Statements of Operations. The following table presents the gross fair value amounts of our derivative financial instruments and the associated notional amounts (in millions): March 31, 2022 December 31, 2021 Derivatives designated as cash flow hedges Notional Fair Value of Assets (1) Fair Value of Liabilities Notional Fair Value of Assets (1) Fair Value of Liabilities Interest rate derivatives $ 600.0 $ 25.6 $ — $ 150.0 $ 0.4 $ — (1) Included within Other Assets, net on the Consolidated Balance Sheets. As of March 31, 2022, the net accumulated gain on our interest rate derivatives before tax effect was $25.6 million. We estimate that $3.4 million will be reclassified as a reduction to interest expense over the next 12 months. The maximum length of time for which we will hedge our exposure to the variability in future cash flows is 10 years. Refer to Note 15, "Fair Value of Financial Instruments," for additional information related to the fair value methodology used for derivative financial instruments. Refer to Note 19, "Subsequent Events," for information regarding derivative transactions completed after March 31, 2022.

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments	Fair Value of Financial Instruments Our financial instruments consist primarily of cash, cash equivalents and restricted cash, marketable securities, notes and other receivables, derivatives assets, debt, warrant, and other liabilities. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures, pursuant to ASC 820, " Fair Value Measurements and Disclosures ." The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: ASC 820, " Fair Value Measurements and Disclosures ," requires disclosure regarding determination of fair value for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumption. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy: Level 1 - Quoted unadjusted prices for identical instruments in active markets that we have the ability to access; 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 significant inputs and significant value drivers are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severity, etc.) in active markets or can be corroborated by observable market data; and Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The unobservable inputs reflect our assumptions about the assumptions that market participants would use. Assets by Hierarchy Level The table below sets forth our financial assets and liabilities (in millions) that required disclosure of fair value on a recurring basis as of March 31, 2022. The table presents the carrying values and fair values of our financial instruments as of March 31, 2022 and December 31, 2021, that were measured using the valuation techniques described above. The table excludes other financial instruments such as other receivables and accounts payable as the carrying values associated with these instruments approximate their fair value since their maturities are less than one year. These are classified as Level 1 in the hierarchy.

This contingent consideration was included within Other liabilities on the Consolidated Balance Sheets at December 31, 2021. 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 in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash, Cash Equivalents and Restricted Cash The carrying values of cash, cash equivalents and restricted cash approximate their fair market values due to the short-term nature of the instruments. These are classified as Level 1 in the hierarchy. Marketable Securities Marketable securities held by us and accounted for under ASC 321 " Investments - Equity Securities " are measured at fair value. Any change in fair value is recognized in the Consolidated Statement of Operations in Gain / (loss) on Remeasurement of marketable securities in accordance with ASU 2016-01 " Financial Instruments - Overall (Subtopic 825-10): Recognition and measurement of financial assets and financial liabilities ." The fair value is measured by the quoted unadjusted share price which is readily available in active markets (Level 1). The change in the marketable securities balance is as follows (in millions): Three Months Ended Year Ended March 31, 2022 December 31, 2021 Beginning Balance $ 186.9 $ 124.7 Additional purchases — 35.5 Change in fair value measurement (34.5) 33.4 Foreign currency translation adjustment 4.4 (9.2) Dividend reinvestment, net of tax 1.5 2.5 Ending Balance $ 158.3 $ 186.9 Installment Notes Receivable on Manufactured Homes Installment notes receivable on manufactured homes are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs, inclusive of default rates, interest rates and recovery rates (Level 3). Refer to Note 4, "Notes and Other Receivables," for additional information. Notes Receivable from Real Estate Developers and Operators Notes receivable from real estate developers and operators are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs including interest rates and counterparty performance (Level 3). The carrying values of the notes generally approximate their fair market values either due to the nature of the note and / or the note being secured by underlying collateral and / or personal guarantees. Refer to Note 4, "Notes and Other Receivables," for additional information. Derivative Assets- Interest Rate Derivatives Interest rate derivatives are recorded at fair value and consist of Treasury locks. The fair value of the Treasury lock is measured using observable inputs based on the 10-year Treasury note rate (Level 2). Secured Debt Secured debt consists primarily of our mortgage term loans. The fair value of mortgage term loans is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information. Unsecured Debt Senior unsecured notes - the fair value of senior unsecured notes is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information. Line of credit and other unsecured debt - consists primarily of our Senior Credit Facility. We have variable rates on our Senior Credit Facility. The fair value of the debt with variable rates approximates carrying value as the interest rates of these amounts approximate market rates. The estimated fair value of our indebtedness as of March 31, 2022 approximated its gross carrying value. Other Financial Liabilities We estimate the fair value of contingent consideration liabilities based on valuation models using significant unobservable inputs that generally consider discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (Level 3). Level 3 Reconciliation, Measurements and Transfers We review the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. Availability of secondary market activity and consistency of pricing from third-party sources impacts our ability to classify securities as Level 2 or Level 3. There were no transfers into or out of Level 3 during the three months ended March 31, 2022. The following table summarizes changes to our financial instruments carried at fair value and classified within Level 3 of the fair value hierarchy for the three months ended March 31, 2022 (in millions):

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Pronouncements - Adopted In August 2020, the FASB issued ASU 2020-06, " Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity ." This update simplifies the accounting for convertible instruments by eliminating the models that require separation of a cash conversion or beneficial conversion feature from the host contract. Under the amended guidance, a convertible debt instrument is treated as one liability accounted for at its amortized cost and convertible preferred stock is considered one equity instrument accounted for at its historical cost, unless (a) there are other features that require bifurcation as a derivative, or (b) convertible debt was issued at a substantial premium. This update also eliminates several triggers for derivative accounting, including a requirement to settle certain contracts by delivering registered shares. Additionally, this update provides clarifications to improve the consistency of earnings per share (EPS) calculations. We adopted the ASU on January 1, 2022. The adoption of this ASU did not have an impact on our Consolidated Financial Statements. Recent Accounting Pronouncements - Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, " Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting ," which provides optional guidance for accounting for contracts, hedging relationships and other transactions affected by the reference rate reform, if certain criteria are met. The provisions of this standard are available for election through December 31, 2022. As of March 31, 2022, we do not expect the reference rate reform will have a material impact on our Consolidated Financial Statements as the majority of our debt has fixed interest rates. Refer to Note 19, "Subsequent Events," for information regarding the amendment of our Senior Credit Facility, now based on SOFR after amendment, completed after March 31, 2022. amendment.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Acquisitions Subsequent to the three months ended March 31, 2022, we completed our previously announced acquisition of Park Holidays in the UK for £950 million (or approximately $1.2 billion). As consideration for the acquisition, we (i) issued an aggregate of 186,044 shares of our common stock with a value of approximately $34.0 million as of the closing to certain individual sellers who are also members of Park Holidays' senior management team, and (ii) paid the remainder of the purchase price in cash. Property Name Property Type Sites, Wet Slips and Dry Storage Spaces Development State / Province or Country Total Park Holidays (1) MH 15,906 1,140 UK $ 1,242.1 Christies Parks (2) MH 249 — UK 10.1 Bluewater Yacht Sales Marina 200 — Various 25.0 Jarrett Bay Bluewater Yacht Sales (3) Marina — — Various 17.6 Total Subsequent Acquisitions 16,355 1,140 $ 1,294.8 (1) Includes 40 owned and two managed properties. (2) Combined with an existing adjacent MH community. (3) Combined with an existing marina. Debt Senior Credit Facility Amendment On April 7, 2022, in connection with the closing of the Park Holidays acquisition, the Operating Partnership as borrower, and Sun Communities, Inc., as guarantor, and certain lenders entered into Amendment No. 1 to the Fourth Amended and Restated Credit Agreement and Other Loan Documents (the "Credit Facility Amendment"), which amended our Senior Credit Facility. The Credit Facility Amendment increases the aggregate amount of our Senior Credit Facility to $4.2 billion with the ability to upsize the total borrowings by an additional $800 million, subject to certain conditions. The increased aggregate amount under the Senior Credit Facility consists of the following: (a) a revolving loan in an amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, Pounds sterling, Euros, Canadian dollars and Australian dollars, subject to certain limitations. The Credit Facility Amendment extends the maturity date of the revolving loan facility to April 7, 2027, assuming the Operating Partnership's exercise of each of its two six-month extension options and, further, the Credit Facility Amendment also extends the maturity date of the term loan facility to April 7, 2025, which may not be extended. Prior to the amendment, the Senior Credit Facility permitted aggregate borrowings of up to $2.0 billion, with an accordion feature that allowed for additional commitments of up to $1.0 billion, subject to the satisfaction of certain conditions. The Senior Credit Facility bears interest at a floating rate based on Adjusted Term SOFR, the Adjusted Eurocurrency Rate, the Daily RFR Rate, the Australian Bank Bill Swap Bid Rate (BBSY), the Daily SONIA Rate or the Canadian Dollar Offered Rate, as applicable, plus, in all cases, a margin, which can range from 0.725 percent to 1.6 percent, subject to certain adjustments. As of March 31, 2022, the margin based on our credit ratings would have been 0.85 percent on the revolving loan facility and 0.95 percent on the term loan facility. Senior Unsecured Notes On April 12, 2022, the Operating Partnership issued $600.0 million of senior unsecured notes with an interest rate of 4.2 percent and a 10-year term, due April 15, 2032 (the "2032 Notes"). The net proceeds from the offering were $592.3 million after deducting underwriters' discounts and estimated offering expenses. We used the net proceeds from the offering to repay borrowings outstanding under our Senior Credit Facility. In connection with the 2032 Notes issuance, we settled four 10-year Treasury rate locks totaling $600.0 million and received a settlement payment of $35.3 million. The balance is included in the Accumulated other comprehensive income in our Consolidated Balance Sheets, and will be amortized as a reduction of interest expense on a straight line basis over the 10-year term of the hedged transaction. Equity Transactions On April 15, 2022, we settled forward sale agreements with respect to 1,200,000 shares of common stock under our at the market offering program. We also settled forward sale agreements with respect to 4,025,000 shares of common stock under the November 2021 Forward Sale Agreements related to an underwritten registered public offering. The aggregate net proceeds from the settlement of these forward sale agreements was $934.9 million. We used the net proceeds to repay borrowings outstanding under our Senior Credit Facility. We have evaluated our Consolidated Financial Statements for subsequent events through the date that this Form 10-Q was issued.
