What Is an FHA One-Time Close Construction Loan?
An FHA One-Time Close construction loan combines the construction loan and the permanent mortgage into a single closing, so you sign one set of documents before ground is broken and never go back to the closing table when the home is finished. FHA backs it with the same 3.5% minimum down payment rule (with a qualifying credit score) that applies to any FHA purchase, per HUD guidelines. The loan converts automatically to a permanent mortgage once the certificate of occupancy is issued, with no second underwriting, no second appraisal, and no second set of closing costs.
Most construction financing works in two separate closings: one loan to build the house, then a refinance into a permanent mortgage once it's done. FHA's One-Time Close (OTC) program collapses that into a single transaction. You get approved once, you close once, and the same loan carries you from the day the builder breaks ground to the day you make your first regular mortgage payment.
That structure matters because two-time-close deals expose you to a second qualification event. If your income changed, your credit dipped, or rates moved between closings, you could lose the deal or the terms you expected. With FHA OTC, the rate and terms are locked at the first closing and the loan simply converts when construction is done and the certificate of occupancy is issued.
How does FHA One-Time Close differ from a traditional construction loan?
A traditional (two-time close) construction loan is really two loans stitched together. The builder draws against a short-term construction note, and once the home is complete, you refinance into a permanent mortgage. That refinance is a brand-new application: new credit pull, new appraisal, new underwriting, and a second round of closing costs.
FHA OTC skips the second transaction entirely. The construction phase and the permanent phase are documented as a single loan from day one. You still go through draws during construction, but there's no refinance event waiting at the end, just an automatic conversion once the home passes final inspection and the certificate of occupancy is on file.
What are the steps from pre-qualification to closing?
The process runs in a fairly fixed order, and skipping a step usually means restarting it:
- Pre-qualification. Your loan officer reviews income, credit, and the FHA loan limit for your county (check the loan limits lookup if you're not sure what applies where you're building) to confirm you fit the program before you sign anything with a builder.
- Builder and plan approval. FHA requires an approved, licensed general contractor and a full set of plans and specs. The builder has to be underwritten alongside you: license, insurance, and a signed construction contract with a fixed budget.
- Appraisal on the finished plans. Because the home doesn't exist yet, the appraiser values the property based on the plans, specs, and comparable completed homes, not on a physical walkthrough.
- Underwriting and the single closing. Underwriting reviews your file and the construction budget together. You close once, funding the lot (if not already owned) and the construction budget into an escrow account controlled by the lender.
- Construction draws. The builder gets paid in stages as work is completed and inspected, not in one lump sum upfront.
- Final inspection and certificate of occupancy. The local building authority signs off, and that certificate is what triggers the loan's conversion.
- Conversion to permanent financing. No new application, no second closing. Your payment shifts from interest-only on the drawn balance to full principal-and-interest on the completed loan.
What happens during construction draws?
The builder doesn't get the full construction budget on day one. Funds sit in an escrow account and get released in stages, typically tied to milestones like foundation, framing, and final finishes. A draw inspection confirms the work is actually done before money moves. This protects you and the lender from paying for work that hasn't happened, and it's the same mechanic used in most construction lending, FHA or not.
During this phase you generally pay interest only on the funds that have actually been drawn, not on the full loan amount. That keeps payments manageable while the home is being built, since you're not paying full principal and interest on a house you can't live in yet.
How does the certificate of occupancy convert the loan to a permanent mortgage?
The certificate of occupancy (CO) is issued by the local building department once the home passes final inspection and is legally habitable. For FHA OTC, that certificate is the trigger event: it tells the lender the construction phase is complete and the loan can convert to permanent amortizing terms. There's no new credit decision at this point. The rate and terms you locked at the original closing carry through, and your payment resets to standard principal-and-interest based on the full loan balance.
This is the entire point of the One-Time Close structure. The FHA construction pillar page walks through the program's eligibility rules in more depth, but the short version is: one approval, one closing, one conversion, no surprises at the finish line.
What credit and down payment do borrowers need?
FHA One-Time Close follows standard FHA guidelines, per HUD: a minimum 3.5% down payment for borrowers with a qualifying credit score, or 10% down for lower scores in FHA's approved range. Because you're financing land, construction, and the permanent loan together, lenders also want to see the full picture upfront, meaning the builder's fixed-price contract, complete plans and specs, and a realistic budget with room for contingencies. If you want to see how the construction budget and eventual mortgage payment interact, the One-Time Close calculator is built for exactly that.
FHA One-Time Close vs. two-time close vs. conventional construction-to-perm
| Feature | FHA One-Time Close | FHA/Conventional Two-Time Close | Conventional Construction-to-Perm |
|---|---|---|---|
| Number of closings | One | Two | One or two, lender-dependent |
| Requalification at completion | Not required | Full new underwriting | Varies by lender |
| Down payment | 3.5% (qualifying credit) or 10%, per HUD | Set by each phase's program | Typically higher than FHA |
| Rate locked at first closing | Yes | No, re-set at refinance | Sometimes |
| Builder requirements | Licensed, approved GC required | Varies | Varies |
| Best fit | Buyers who want certainty and lower down payment | Buyers comfortable requalifying later | Buyers who don't need FHA flexibility |
A real scenario
A client came to Jesse wanting to build on a lot they already owned, using FHA One-Time Close to keep the down payment low. Mid-construction, the builder submitted a change order after a framing issue pushed the budget higher than the original contract. Because the loan had a contingency reserve built into the original construction budget at closing, the increase was absorbed without reopening underwriting or requiring a new appraisal. The home passed final inspection, the certificate of occupancy was issued, and the loan converted to permanent financing on schedule, with the same rate and terms locked at the first closing. The lesson: build a realistic contingency into the construction budget before you close, because FHA OTC doesn't give you a second closing to fix a budget that ran short.
Who should consider this over other loan options?
FHA One-Time Close makes the most sense for buyers building a primary residence who want the lower down payment FHA is known for without taking on the requalification risk of a two-time close. If you're a first-time buyer building rather than buying existing, it's worth comparing against a standard FHA purchase loan on an already-built home, since construction timelines and builder risk add complexity a resale purchase doesn't have. If your income or credit profile doesn't fit FHA guidelines, or you're building an investment property rather than a primary residence, a conventional construction-to-perm product or a dedicated bridge and construction loan may fit better.
Frequently asked questions
What is FHA One-Time Close?
FHA One-Time Close is a construction loan that combines the construction financing and the permanent mortgage into a single closing, so you don't refinance once the home is built.
How much down payment does FHA One-Time Close require?
It follows standard FHA guidelines: 3.5% down for borrowers with a qualifying credit score, or 10% down for borrowers in FHA's lower approved credit range, per HUD.
Does the loan get reunderwritten when construction finishes?
No. The certificate of occupancy triggers an automatic conversion to permanent financing at the rate and terms locked at the original closing, with no new credit decision.
Can I use land I already own with FHA One-Time Close?
Yes, an owned lot can be included in the transaction, and its value can count toward your equity in the deal depending on how the file is structured.
Who has to approve the builder on an FHA One-Time Close loan?
The lender underwrites the general contractor alongside you, verifying license, insurance, and a signed fixed-price construction contract before closing.
How are the funds paid to the builder during construction?
Funds are held in a lender-controlled escrow account and released in staged draws tied to inspected construction milestones, not paid out in one lump sum.
What happens if construction costs exceed the original budget?
A contingency reserve built into the original construction budget at closing can absorb reasonable overages; without one, a large overage may require the borrower to cover the difference out of pocket.
Is FHA One-Time Close only for single-family homes?
It's typically used for primary-residence, site-built single-family homes; check current program eligibility with your loan officer for manufactured or unusual property types.
