Real Estate [Abstract]
Land Under Development	Land Under DevelopmentOn a limited basis, we directly acquire raw land parcels already zoned for its intended use to develop into finished lots.  Land under development includes the land acquisition costs, direct improvement costs, capitalized interest where applicable, and real estate taxes.As of March 31, 2020, we directly owned a total of five separate raw land parcels with a carrying value of $68,139 that are expected to produce approximately 600 finished lots. We also have additional funding commitments of approximately $5,900 under a joint development agreement related to one parcel, a portion of which we expect will be offset by development credits of approximately $2,700. None of the raw parcels had any indicators of impairment as of March 31, 2020.
