Can You Do a One-Time-Close Construction Loan?

Yes — and on most new-build scenarios it's the structure to use. A one-time-close (OTC) construction-to-permanent loan does both jobs at a single closing: it funds the build (interest-only draws to the builder during construction), then automatically converts to a 30-year permanent mortgage at completion. The permanent rate is locked at the start of construction, so you don't carry market risk for the 6–12 months the build takes. OTC is supported across all the major loan programs — FHA OTC (HUD Handbook 4000.1, II.A.8.h), VA OTC (VA Pamphlet 26-7, Chapter 3), and Conventional OTC (Fannie Mae Selling Guide B5-3.1) — with slightly different rules at each program. The alternative is a "two-time close": one closing for a short-term construction loan, then a second closing to refinance into a permanent mortgage. Two closings cost more and expose you to whatever rates do during the build.

The handbook view (what the rules actually say)

Each agency has its own framework for construction-to-permanent financing. The shared structure is "single-closing, subject-to-completion appraisal, automatic conversion at completion." The differences live in the eligibility details:

• FHA OTC: One-time-close construction-to-permanent financing is expressly permitted. The builder must be approved by the lender, plans and specs are on file before the first draw, and the appraisal is performed subject to completion of the plans and specs. Maximum mortgage is calculated against the lesser of acquisition cost (lot + construction) or appraised value. Standard FHA program rules apply to the permanent loan — 3.5% minimum down with a 580+ FICO, UFMIP financed into the loan, monthly MIP for the life of the loan when LTV is above 90%. (Source: HUD Handbook 4000.1, II.A.8.h, Construction-to-Permanent and Building on Own Land Programs.)
• VA OTC: VA permits construction-to-permanent loans with a single closing. The veteran's entitlement attaches to the permanent loan. The builder must be registered with VA, the property must meet VA Minimum Property Requirements at completion (with a final inspection), and the standard VA Funding Fee applies to the permanent loan amount. Zero-down financing is available subject to entitlement and lender policy. (Source: VA Lender's Handbook, Pamphlet 26-7, Chapter 3, Section 3.07, Construction Loans; 38 CFR § 36.4360.)
• Conventional OTC: Fannie Mae permits single-closing construction-to- permanent transactions. LTV is calculated against the lesser of (a) total acquisition cost — lot purchase + construction cost — or (b) the subject-to-completion appraised value. Loan-to-value, FICO, DTI, and reserve requirements follow standard Fannie eligibility for the permanent loan type. Freddie Mac permits the same structure under analogous Single-Family Seller/Servicer Guide provisions. (Source: Fannie Mae Selling Guide B5-3.1, Conversion of Construction-to-Permanent Financing — Single- Closing Transactions.)
• Subject-to-completion appraisal mechanics. On every OTC, the appraiser values the not-yet-built property based on the builder's plans and specs and the lot. A final inspection after construction confirms the home was built to those plans and specs before the permanent loan funds. If the as-built value comes in lower than expected, that doesn't typically derail the conversion — the loan was already approved at the original LTV — but material deviations from the originally approved plans can trigger a re-underwrite.
• TRID disclosure framework (12 CFR Part 1026) applies to construction- to-perm loans. Single-closing transactions get a single set of disclosures covering both phases; two-closing transactions require separate disclosure sets for each.

The plain-English translation

The mechanics behind a one-time-close loan, in order of how you experience them:

• You pick a builder, get plans and a fixed-cost contract, and bring it to the lender. The lender vets the builder (license, insurance, financial stability, completed- project track record).
• The appraiser values the home as if it's already built — based on the plans, the specs, and comparable completed homes nearby. The loan is sized off that after-completion number, capped by the total acquisition cost (lot + construction).
• You close. One closing — title, escrow, lender fees, transfer taxes paid once. Your permanent 30-year rate is locked at this closing (often with a one-time float-down option in case rates drop during the build).
• During construction, the lender funds the builder in draws as work completes. You pay interest only on the funds disbursed so far, not on the full loan amount. The builder typically handles draw inspections and submits draw requests directly.
• When the home is finished and the final inspection passes, the loan automatically modifies to a fully amortizing 30-year mortgage at the locked rate. No second closing, no second appraisal in most cases, no re-underwriting.

Side-by-side: FHA OTC vs VA OTC vs Conv OTC

The table is a rule of thumb, not a quote. Specific terms — the actual lock length, whether the lender offers float-down, builder-approval friction — vary per investor. The right move is to pre-screen a few wholesale investors before picking a builder, because the lender's builder-approval process can disqualify a builder you've already committed to.

Lender overlays — where the rules get tighter

Construction-to-perm is one of the most overlay-heavy product categories because the lender is carrying construction risk on top of credit risk. Common overlays:

• FICO floors above the agency minimum. HUD allows 580 on regular FHA; on FHA OTC, most lenders overlay to 640 or 680. VA technically has no FICO minimum; lenders overlay to 620 or 640 on VA OTC. Conventional OTC similarly overlays above the standard 620 conforming minimum.
• Many retail lenders simply don't offer OTC. Their wholesale channel might support it, but the retail loan officer's product menu won't include it — so a borrower asking is told "we do a construction loan and then refinance you," which is the two-time-close structure with the second set of closing costs and rate risk baked in. As an independent broker we shop the wholesale channel directly.
• Builder-approval requirements vary widely. Some investors approve a builder once and let any borrower use them; others require borrower-by-borrower re-approval. Custom and small-volume builders face more scrutiny than national production builders.
• Reserve requirements above program minimum. 6 months PITI in reserves is common on OTC even when AUS doesn't call for it. Build-overrun cushion.
• Float-down policies aren't standardized. Some products allow one float-down with a minimum rate-drop threshold (e.g., 0.25%); some require a waiting period; a few don't offer one at all. Read the lock agreement, not the brochure.
• DTI caps may tighten on OTC. Even when the agency permits 50%+ DTI with AUS approval, lenders may cap OTC at 45%.

Which lenders we actually use for this scenario

Yes — across all three of the major program types. One-time-close construction-to-permanent (OTC, or C2P) exists as a conventional product per Fannie Mae B5-3.1, as an FHA product per HUD 4000.1 Section II.A.8.h, and as a VA product per VA Pamphlet 26-7 Chapter 3. Same skeleton across all three: one application, one underwrite, one closing at the front, construction draws during the build, automatic conversion to the permanent loan when the certificate of occupancy hits. No second closing, no second appraisal, no second title policy, no second underwrite at whatever rates exist 12 months later.

The broker channel's job here is matching the borrower's profile to the right rule book and then to the right wholesaler within that rule book. A veteran with no down payment goes into a VA OTC — and there's a much shorter list of wholesalers actually writing VA OTC than writing the conventional or FHA versions. An FHA OTC fits a borrower with the FHA-style profile (lower credit threshold, 3.5% down) building a primary residence. Conventional OTC fits the conforming-grade borrower with 5-20% down. I keep a working list of which wholesalers are actively writing each version because it rotates — a lender will be in the market one quarter and pulled the next.

The underwriting layer that's common to all three: subject-to-completion appraisal (the appraiser values the property based on plans, specs, and the builder's contract as if it were already done), builder approval by the lender (each wholesaler has a builder-vetting process with financial statements, references, prior projects), construction timeline cap (most programs run 12 months max, some 9), and a draw schedule tied to construction milestones.

Real-world cases

I've seen this pattern over and over: borrower walks into a local bank, gets quoted a stand-alone construction loan (12-month interest-only balloon), and is told “we'll refinance you into a permanent at the end.” Two-time close. That works fine when everything goes right — but “everything goes right” means rates don't move against them during the build, their income holds steady, their credit profile is intact at month 11 when they have to re-qualify, and the appraisal at the end supports the take-out balance. Any one of those slips and they can be stuck holding a construction loan that won't take out cleanly.

A typical OTC case: borrower locks the rate at construction start with a float-down option (terms vary by lender, but most programs let the borrower take the lower rate if the market drops by some threshold before conversion), pays one set of closing costs at the front, makes interest-only payments on the disbursed balance during the build, and on COO the loan flips to a fully-amortizing permanent at the locked terms. The rate-risk is gone from the day the dirt moves. That's the structural advantage — it's not really about being “cheaper” on rate, it's about removing the second closing's cost stack and the take-out rate risk.

Where I've seen OTC NOT be the right tool: borrower wants a builder the wholesaler won't approve (custom one-off builders sometimes can't pass the financial-statement review), or the build timeline is genuinely longer than the lender's lock window allows, or the borrower's profile is clean for the permanent loan but tight for the construction-phase reserves requirement. In those cases the two-time-close path can still be correct — but the borrower needs to walk in with eyes open about what happens at the take-out.

How the big retail lenders typically handle this

The major retail lenders all have a branded one-time-close product. Same skeleton as everything described above. They market them well — borrowers usually hear about OTC for the first time at a retail lender, not from a builder or a broker. That's a feature of the marketing, not of the product economics.

Where the broker channel's advantage shows up: a borrower walking into a retail lender will be quoted that lender's one OTC product on whichever program type that lender prefers — usually conventional, sometimes FHA, occasionally VA depending on the shop. They have no easy way to see whether a different lender on the same program type would price better, or whether a different program type entirely (FHA OTC instead of conventional, for example) would deliver a better answer once MI and rate are stacked.

The short answer to “can you do a one-time-close construction loan”: yes — and the more useful question is which program type and which wholesaler fit the specific borrower, the specific builder, and the specific timeline. That's the broker-floor work. The product exists in all three rule books; picking the right combination is where the experience matters.

A simple decision rule

A 30-second filter for whether OTC is the right structure:

1. 1Building a primary residence ground-up on a lot you own (or are buying)? OTC is almost always the right structure — one closing, locked rate, no re-qualification risk at completion.
2. 2Veteran with full entitlement? Start with VA OTC — zero-down, no monthly MI, Funding Fee waived if you have a service-connected disability rating.
3. 3Limited down payment, FICO 580–700? Compare FHA OTC vs Conv OTC. FHA wins at lower credit; Conventional wins at higher credit (no lifetime MIP).
4. 4Building a second home, investment property, or anything non-owner-occupied? FHA and VA are out — Conv OTC (program-dependent) is the path.
5. 5Builder isn't on any lender's pre-approved list and resists being vetted? That's a signal — either find a builder who's comfortable with the process, or accept that lender selection will be narrower.
