Already own the lot? FHA has a specific Building on Own Land framework.
FHA treats construction on land the borrower already owns differently from simply buying a completed house. Land ownership, construction cost, liens and acquisition cost drive the maximum-mortgage analysis.
Acquisition cost matters
For applicable cases, FHA Connection uses Acquisition Cost rather than ordinary sales price in the LTV calculation when Building on Own Land is identified. HUD's current system guidance notes this treatment for case numbers assigned on or after May 31, 2024.
Land equity
Existing equity in eligible land can be important to the transaction, but the lender must establish ownership, liens, cost basis and the applicable FHA calculation rather than simply calling the land value a cash down payment.
Construction documentation
Plans/specifications, construction status, builder/contractor information, appraisal and new-construction documentation must satisfy the applicable FHA pathway.
Source standard
Mortgage Navigator uses HUD/FHA Handbook 4000.1 and current HUD program materials as its policy baseline. Current Handbook update: August 12, 2026. Draft policy is not treated as effective policy.
