Subsequent Events [Abstract]
Subsequent Events	Subsequent Events During October 2017, we sold 336,290 shares of common stock as part of the ATM equity offering program at a weighted average price of $85.13, resulting in net cash proceeds of $28.3 million. Our Board of Directors has approved a new ATM equity offering program having an aggregate offering price of up to $200.0 million. On October 16, 2017, we entered into a $204 million secured facility with Fannie Mae, maturing in 2037 and bearing a 3.97% fixed interest rate. The loan is secured by five manufactured home communities. We used the proceeds to pay, in full, $194.2 million of loans that would have matured in 2018. We incurred approximately $2.2 million in prepayment penalties associated with the debt repayment. On October 27, 2017, we entered into a Second Amended and Restated Credit Agreement (the “Second Amended and Restated Credit Agreement”) by and among us, MHC Operating Limited Partnership, Wells Fargo Bank, National Association, as Administrative Agent (the “Administrative Agent”) and other lenders named therein, which amends and restates the terms of the obligations owed by us under the Amended, Restated and Consolidated Credit Agreement dated as of July 17, 2014 pursuant to which we have access to a $400 million unsecured line of credit (the “LOC”) and the $200 million senior unsecured term loan facility (the “Term Loan”). The LOC maturity date was extended to October 27, 2021, and this term can be extended an additional year in two six month increments, subject to certain conditions. The LOC bears interest at a rate of LIBOR plus 1.10% to 1.55% and requires an annual facility fee of 0.15% to 0.35%. We also extended the term of our Term Loan. The Term Loan now matures on April 27, 2023 and has an interest rate of LIBOR plus 1.20% to 1.90% per annum. For both the LOC and Term Loan, the spread over LIBOR is variable based on leverage throughout the respective loan terms. We incurred commitment and arrangement fees of approximately $3.6 million to enter into the Second Amended and Restated Credit Agreement.
