Real Estate [Abstract]
Land Under Development	Land Under DevelopmentOn a limited basis, we directly acquire raw land parcels already zoned for their 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 September 30, 2020, we directly owned three separate raw land parcels with an aggregate carrying value of $63,608 that are expected to produce approximately 500 finished lots. We also had additional funding commitments of approximately $5,200 under a joint development agreement related to one parcel, a portion of which we expect will be offset by development credits of approximately $2,900. None of the raw parcels had any indicators of impairment as of September 30, 2020.
