An FHA one-time close loan — also called an FHA construction-to-permanent loan or a single-close construction loan — lets you finance the land, the construction, and the finished mortgage in a single FHA-insured transaction. You sign once, before a shovel goes in the ground, and the loan converts to a normal FHA mortgage at completion.
That structure matters, because the alternative is a two-time close: a short-term construction loan from a bank at a higher rate, then a separate refinance into permanent financing. In a two-close structure you qualify twice, pay closing costs twice, and carry the risk that rates or your credit have moved by the time the house is done.
How the one-time close actually works
- Qualify and close. You are underwritten to the finished loan amount up front, using the same FHA rules covered on our FHA requirements page.
- Funds are held and drawn. The lender disburses to the builder on a documented draw schedule as stages complete — foundation, framing, mechanicals, drywall, finish.
- Inspections gate each draw. An inspector verifies completed work before money moves.
- Completion and conversion. When the certificate of occupancy is issued and the final inspection clears, the loan modifies into a permanent FHA mortgage with the rate you already locked.
Down payment and how the loan amount is set
The 3.5% minimum required investment is unchanged. What changes is the number it is applied to. On a construction-to-permanent loan the maximum mortgage is based on the lesser of the appraised value of the completed property or the total acquisition cost — the documented cost of the land plus the construction contract plus permitted soft costs.
| Scenario | Land | Construction contract | Appraised on completion | Basis used | 3.5% down |
|---|---|---|---|---|---|
| Cost equals value | $80,000 | $270,000 | $350,000 | $350,000 | $12,250 |
| Appraises high | $80,000 | $270,000 | $385,000 | $350,000 (cost) | $12,250 |
| Appraises low | $80,000 | $270,000 | $330,000 | $330,000 (value) | $11,550 + $20,000 gap |
The third row is the risk case in every construction file: if the finished home appraises for less than what it cost to build, FHA lends on the lower number and you cover the difference in cash.
Land you already own counts. If you bought the lot outright, its documented value is credited toward your required investment, which is how many one-time close borrowers arrive at closing with little or no additional cash. Land acquired as a gift follows the FHA gift funds rules.
Builder and property requirements
FHA does not insure owner-built homes. You need a licensed, insured general contractor who the lender will underwrite: license verification, general liability and workers' compensation coverage, references on completed projects, and financial capacity to carry the job between draws.
The plans and the finished home must satisfy the same Minimum Property Requirements that apply to any FHA appraisal, plus construction-specific standards:
- A fixed-price construction contract with a complete scope of work, specifications, and plans
- A firm completion timeline, typically 12 months or less
- Builder's risk insurance during the build and hazard coverage at completion
- A 10-year insured protection plan or the applicable warranty where the home is proposed construction
- A final inspection and a certificate of occupancy issued by the local authority
- Compliance with HUD's Minimum Property Standards — see HUD's Single Family Housing Policy Handbook 4000.1 and our appraisal guide
Costs beyond the down payment
Construction files carry line items a stock purchase does not: plan review, permits, a construction inspection fee per draw, a builder's risk policy, and the interest that accrues on drawn funds during the build. Most FHA one-time close programs allow construction-period interest and inspection fees to be financed into the loan rather than paid monthly out of pocket.
The permanent mortgage carries the same upfront MIP of 1.75% and the same annual mortgage insurance as any other FHA loan. Run the numbers on the MIP calculator before you commit to a contract price.
One-time close versus 203(k) versus a two-close construction loan
| One-time close | FHA 203(k) | Two-close construction | |
|---|---|---|---|
| What it builds | A new home from the ground up | Repairs or rehab of an existing home | A new home |
| Closings | One | One | Two |
| Requalification | None | None | Yes, at the refinance |
| Rate risk | Locked before construction | Locked at closing | Exposed until the refinance |
| Down payment | 3.5% | 3.5% | Often 10–20% at the bank |
| Best for | Buyers building on a lot with a licensed builder | Buyers of a fixer-upper | Borrowers who don't qualify for a single close |
If the house already exists and only needs work, the 203(k) is the right tool. If the house does not exist yet, the one-time close is the only FHA path that gets you a 3.5% down payment and a single set of closing costs.
Timeline expectations
Underwriting a construction file takes longer than a purchase because the builder package is underwritten alongside the borrower. Plan on three to six weeks from application to closing, then the contract build period — commonly six to twelve months — then two to four weeks from certificate of occupancy to final conversion and first permanent payment.
The most common delay is not credit. It is an incomplete builder package: an expired license, a missing insurance certificate, or a construction contract without a fixed price. Ask your builder for those three documents the day you start.
Who this loan is not for
If you want to do the work yourself, if your builder will not sign a fixed-price contract, if the finished loan amount exceeds your county FHA loan limit, or if you need to move within 90 days, a one-time close is the wrong product. Say that out loud early — it saves a wasted appraisal fee.
