BSPRA is equal to 10% of all eligible costs, excluding land value (for new construction) or as-is value (for substantial rehabilitation projects), as a mortgageable cost. Note, however, that BSPRA is only a mortgageable cost used for underwriting purposes; BSPRA is not a source of cash for payments of any amounts due to the contractor or otherwise. BSPRA is a non-cash cost and non-cash source in the underwriting and settlement statements.
