Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Revenue Recognition Our revenue streams are predominantly derived from customers renting our Sites or entering into membership subscriptions. Leases with customers renting our Sites are accounted for as operating leases. The rental income associated with these leases is accounted for in accordance with the Accounting Standards Codification (“ASC”) 842, Leases, and is recognized over the term of the respective lease or the length of a customer’s stay. MH Sites are generally leased on an annual basis to residents who own or lease factory-built homes, including manufactured homes. RV and marina Sites are leased to those who generally have an RV, factory-built cottage, boat or other unit placed on the site, including those customers renting marina dry storage slips. Annual Sites are leased on an annual basis, including those Northern Properties that are open for the summer season. Seasonal Sites are leased to customers generally for one to six months. Transient Sites are leased to customers on a short-term basis. We do not separate expenses reimbursed by our customers (“utility recoveries”) from the associated rental income as we meet the practical expedient criteria of ASC 842, Leases to combine the lease and non-lease components. We assessed the criteria and concluded that the timing and pattern of transfer for rental income and the associated utility recoveries are the same and, as our leases qualify as operating leases, we account for and present rental income and utility recoveries as a single component under Rental income in our Consolidated Statements of Income and Comprehensive Income. In addition, customers may lease homes that are located in our communities. These leases are accounted for as operating leases. Rental income derived from customers leasing homes is also accounted for in accordance with ASC 842, Leases and is recognized over the term of the respective lease. The allowance for credit losses related to the collectability of lease receivables is presented as a reduction to Rental income. Lease receivables are presented within Other assets, net on the Consolidated Balance Sheets and are net of an allowance for credit losses. The estimate for credit losses is a result of our ongoing assessments and evaluations of collectability, including historical loss experience, current market conditions and future expectations in forecasting credit losses. Annual membership subscriptions and membership upgrades are accounted for in accordance with ASC 606, Revenue from Contracts with Customers. Membership subscriptions provide our customers access to specific Properties for limited stays at a specified group of Properties. Upgraded memberships provide enhanced benefits for members in good standing, including longer stays, the ability to make earlier reservations, potential discounts on rental units, and potential access to additional properties. Beginning in the first quarter of 2025, membership upgrade product offerings include two-to four-year term subscription products, that require a non-refundable upfront deposit. Prior to the introduction of subscription-based upgrade products, membership upgrades required non-refundable upfront payments, and members in good standing are entitled to enhanced benefits for as long as they choose to remain in the program. Membership subscriptions, including subscription-based membership upgrades, are presented within Annual membership subscriptions on the Consolidated Statements of Income and Comprehensive Income. Payments for membership subscriptions are deferred and recognized on a straight-line basis over the period during which access to Sites at certain Properties is provided. Membership subscription receivables are presented within Other assets, net on the Consolidated Balance Sheets and are net of an allowance for credit losses. Non-refundable upfront payments are recognized on a straight-line basis over 24 years and are presented within Membership upgrade revenue on the Consolidated Statements of Income and Comprehensive Income. Financed upgrade sales (also known as contract receivables) are presented within Notes receivable, net on the Consolidated Balance Sheets and are net of an allowance for credit losses. Revenue from home sales is recognized when the earnings process is complete. The earnings process is complete when the home has been delivered, the purchaser has accepted the home and title has transferred. We have a limited program under which we purchase loans made by an unaffiliated lender to homebuyers at our Properties. Financed home sales (also known as chattel loans) are presented within Notes receivable, net on the Consolidated Balance Sheets and are net of an allowance for credit losses. (b) Restricted Cash As of March 31, 2025 and December 31, 2024, restricted cash consisted of $21.3 million and $19.0 million, respectively, primarily related to cash reserved for customer deposits and escrows for insurance and real estate taxes. (c) Fair Value of Financial Instruments We disclose the estimated fair value of our financial instruments according to a fair value hierarchy. The valuation hierarchy is based on the transparency of the lowest level of input that is significant to the valuation of an asset or a liability as of the measurement date. The three levels are defined as follows: Level 1 - Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The carrying values of cash and restricted cash, accounts receivable and accounts payable approximate their fair market values due to the short-term nature of these instruments. The carrying value of the notes receivable approximates the fair market value as the interest rates are generally comparable to current market rates. Concentrations of credit risk with respect to notes receivable are limited due to the size of the receivable and geographic diversity of the underlying Properties. The fair market value of mortgage notes payable, the term loan and interest rate derivatives are measured with Level 2 inputs using quoted prices and observable inputs from similar liabilities as disclosed in Note 7. Borrowing Arrangements and Note 8. Derivative Instruments and Hedging Activities. We also utilize Level 2 and Level 3 inputs as part of our determination of the purchase price allocation for our acquisitions. (d) Insurance Recoveries We carry comprehensive insurance coverage for losses resulting from property damage and environmental liability and business interruption claims on all of our properties. We record the estimated amount of expected insurance proceeds for property damage, clean-up costs and other losses incurred as an asset (typically a receivable from our insurance carriers) and income up to the amount of the losses incurred when receipt of insurance proceeds is deemed probable. Any amount of insurance recovery in excess of the losses incurred and any amount of insurance recovery related to business interruption are considered a gain contingency and will be recognized in the period in which the insurance proceeds are received. During the quarters ended March 31, 2025 and March 31, 2024, we recognized approximately $0.8 million and $0.5 million, respectively, of expense related to debris removal and cleanup related to Hurricane Ian, Hurricane Milton and Hurricane Helene, with $0.6 million and $0.5 million of offsetting insurance recovery revenue accruals which offset the expenses incurred during the same periods. During the quarter ended March 31, 2024, we also recorded $14.8 million of insurance recovery revenue in excess of expenses and business interruption proceeds related to Hurricane Ian. The debris and cleanup costs and offsetting recovery accrual and reimbursement of capital expenditures are reflected in Casualty-related charges/(recoveries), net on the Consolidated Statements of Income and Comprehensive Income. During the quarters ended March 31, 2025 and March 31, 2024, we recognized business interruption recovery revenue of approximately $1.8 million and $1.9 million, respectively, related to Hurricane Ian. (e) New Accounting Pronouncements In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”). ASU 2024-03 requires additional disaggregated disclosure of the nature of expenses included in the income statement into certain required expense categories. This update is effective for annual periods beginning after December 15, 2026, with early adoption being permitted. We are currently evaluating the impact of ASU 2024-03 on our consolidated financial statements.
