✓ Written and reviewed by Ken Clark Jr., Certified Mortgage Advisor, NMLS #225375 . Published September 27, 2026 . Updated September 27, 2026

One application, one closing, one set of closing costs.

A one-time close loan finances the land (if needed) and the build, then becomes your regular mortgage when the home is finished. Ken Clark Jr. helps buyers, landowners, and veterans structure one-time close financing through PRMG programs in Sacramento, Northern California, New Jersey, and nationwide where licensing permits.

Short answer: A one-time close construction loan (also called single-close or construction-to-permanent) combines the construction loan and the permanent mortgage into one loan with one closing. You qualify once, funds are released in draws during the build, and the loan converts to a regular mortgage when the home is complete, without a second closing. Depending on eligibility, it may be available through VA, FHA, USDA, conventional, and jumbo programs.

  • Other names: single-close, single-closing, construction-to-permanent, C2P, OTC.
  • Closings: one, at the start.
  • During construction: funds released in draws; on FHA and VA, in most cases no mortgage payments until completion.
  • At completion: final inspection, then automatic conversion to the permanent loan.
  • Programs: VA, FHA, USDA, conventional, and jumbo, depending on eligibility and state.
  • Land: can be purchased at closing or already owned; equity may help.

What is a one-time close construction loan?

Short answer: A one-time close loan is a single mortgage that covers both phases of a build: the construction period and the long-term (permanent) loan. You sign once, at the beginning.

With a one-time close loan, the permanent loan terms are written into the loan documents at closing, so when construction is finished the loan converts to the permanent phase automatically. Fannie Mae describes it this way in its Selling Guide: because the loan documents specify the permanent financing terms, the construction loan automatically converts upon completion. During construction, the lender manages disbursements to the builder, contractors, and suppliers.

One-time close vs two-time close

Short answer: one-time close has one closing and no requalifying at the end. Two-time close has a construction-only loan, then a second closing for the mortgage.

ClosingsOneTwo
Closing costsOne setTwo sets
Qualify again at completionGenerally no, though some documents may be updatedYes
Permanent loan termsSet at the start (program dependent)Chosen after construction
Exposure to rate, income, or credit changes mid-buildLowerHigher
Flexibility to shop the final loanLowerHigher

For most owner-occupied buyers, the certainty of one closing outweighs the flexibility of shopping the final loan later. If your income is changing or you expect to pay down a large amount at completion, a two-time close may be worth comparing.

How does a one-time close loan work, step by step?

  1. Strategy call. Land, budget, builder, timeline, and which program fits.
  2. Application and credit review. Income, assets, credit, and debts, just like a purchase loan.
  3. Builder registration. Your builder submits license, insurance, experience, and identification for program eligibility review. See builder requirements.
  4. Plans, contract, and budget. Final plans and specifications, a signed contract, and a line-item budget with a contingency.
  5. Appraisal. Completed based on the plans to estimate the as-completed value.
  6. One closing. The lot is purchased or refinanced, the construction funds are set aside, and the permanent loan terms are documented.
  7. Construction and draws. Funds are released as work is completed and verified.
  8. Completion and conversion. Final inspection and completion report, certificate of occupancy, then the loan converts to the permanent phase.

Which programs offer one-time close financing?

Short answer: depending on eligibility and state, PRMG programs may offer one-time close financing through VA, FHA, USDA, conventional, and jumbo loans. Each has its own down payment, property, and builder requirements.

ProgramMay fitKey considerations
VA one-time closeEligible veterans and service membersMay allow no down payment with full entitlement; builder needs a VA builder ID; primary residence
FHA one-time closeModerate credit or smaller down paymentFHA minimum 3.5% down for eligible borrowers; FHA loan limits and construction guidelines apply
USDA one-time closeIncome-eligible buyers in eligible rural areasMay allow no down payment; location and income limits apply
Conventional one-time closeStronger credit, second homesConstruction period rules and LTV limits set by the investor
Jumbo constructionCustom homes above conforming and high-balance limitsAvailable for eligible borrowers; larger down payment and reserves typically required

PRMG programs are available in every state where PRMG is licensed (all states except New York). In California, permits are typically required before closing. The first step is matching your scenario to the programs that fit.

How long can the construction period be?

Short answer: it depends on the program. Many single-family builds finish in about 6 to 12 months, and programs set limits on how long the construction phase can run.

As one example, Fannie Mae's conventional single-closing guidelines limit any single construction period to 12 months and the total construction period, including extensions, to 18 months. Government programs and investors set their own limits. Build your schedule with a cushion for weather, inspections, and permitting.

What do I pay during construction?

Short answer: it depends on the program. On FHA and VA one-time close loans, in most cases you make no mortgage payments until the home is finished, because the interim interest is typically built into the builder's contract price. USDA one-time close commonly sets aside a payment reserve at closing. Conventional one-time close usually requires interest-only payments on the funds drawn so far.

You are typically responsible for property taxes that come due during construction. Your loan documents will state exactly what is due and when full principal and interest payments begin. If you are renting while you build, plan for that too.

Is my rate locked at closing?

Short answer: with most one-time close structures the permanent loan terms are set in the loan documents at closing, which is one of the main benefits. The exact rate lock and any float-down or modification options depend on the program and market conditions.

Ask specifically how the rate works during construction versus after conversion, and whether any extension of the construction period affects your terms.

Can I use land I already own, or buy the lot at closing?

Short answer: both are possible. If you already own the lot, its equity may count toward the down payment. If you are buying it, some programs finance the lot purchase and construction together at the single closing.

For conventional single-closing loans, Fannie Mae treats these differently. If you already own the lot, the loan is structured as a limited cash-out refinance and the loan-to-value is based on the as-completed appraised value of the lot and home. If you are buying the lot at closing, the loan-to-value is based on the lesser of the total purchase price (lot plus construction) or the as-completed value. That is why owned land can be such a powerful source of equity. More on using land equity.

How does the appraisal work on a one-time close loan?

Short answer: the appraiser values the home as if it were already built, based on your plans and specifications. At completion, the appraiser confirms the home was built as planned.

Under Fannie Mae's conventional guidelines, for example, the appraisal can be no more than four months old at closing, and a completion report (Form 1004D) is required when construction is finished. If the finished home is worth less than expected, the loan may need to be adjusted. This is why a budget that lines up with what similar homes sell for matters so much.

Ken's Take: mistakes that cost one-time close borrowers time

Example: one-time close with lot purchase (hypothetical)

Educational illustration only. Not an actual client, loan offer, or commitment to lend.

A buyer in Placer County finds a $175,000 lot with utilities at the street. Their builder's budget is $525,000 including a contingency, and the as-completed appraisal comes in at $725,000. Total cost is $700,000.

With a one-time close loan, the lot purchase and the construction budget are financed at one closing. The down payment is based on the program's limits applied to the lesser of the $700,000 total cost or the $725,000 appraised value (for conventional), and the rest of the construction funds are released in draws as the home is built. When the home is finished and inspected, the loan converts to the permanent mortgage with no second closing.

Frequently asked questions

Answered by Ken Clark Jr., Certified Mortgage Advisor. Program availability and requirements vary and are subject to change.

What is a one-time close construction loan?

It is a single loan that covers both the construction phase and the permanent mortgage, with one closing at the start. The loan converts to the permanent mortgage when construction is complete.

Is one-time close the same as construction-to-permanent?

Yes. One-time close, single-close, single-closing, and construction-to-permanent generally describe the same structure: construction financing and the permanent mortgage in one loan.

What is the difference between one-time close and two-time close?

One-time close has one closing and one set of closing costs, and you generally do not requalify at the end. Two-time close uses a construction-only loan and then a separate mortgage, which means two closings and qualifying again.

Can I get a VA one-time close construction loan?

Eligible veterans may be able to use VA financing to build with a one-time close structure, subject to entitlement, a builder with a VA builder ID, appraisal, and program guidelines.

Can I get an FHA one-time close construction loan?

FHA allows construction-to-permanent financing for eligible borrowers, subject to FHA loan limits, construction guidelines, and lender requirements.

Can I get a USDA one-time close construction loan?

USDA construction financing may be available for income-eligible buyers building in eligible rural areas, subject to program guidelines and availability.

Do I have to requalify when construction is finished?

With one-time close you generally do not go through a second full approval, but some documents such as credit or income may need to be updated at conversion, depending on the program and how long construction took.

What happens if construction takes longer than planned?

Many programs allow extensions within limits. Fannie Mae conventional single-closing loans, for example, allow up to 18 months total. Extensions may have costs and conditions, so build in a schedule cushion.

Do I make mortgage payments during construction?

It depends on the program. On FHA and VA one-time close loans, in most cases no mortgage payments are due until the home is complete. USDA commonly uses a payment reserve set up at closing. Conventional one-time close usually requires interest-only payments on funds drawn. Full payments begin after conversion.

Can I buy the lot with a one-time close loan?

Often yes. Some programs finance the lot purchase and construction together at one closing, subject to the lot, builder, plans, and program guidelines.

Can I use a lot I already own?

Yes, in many cases. Equity in land you own may count toward the down payment, and any existing loan on the lot is usually paid off at closing.

Can I build a manufactured or modular home with one-time close?

Some programs allow modular homes and multi-section manufactured homes on a permanent foundation, subject to property and program requirements. Single-wide homes, log homes, and post-frame or barndominium construction are commonly ineligible on government programs. Ask before you order the home.

Who manages paying the builder?

The lender or its draw administrator releases funds in draws as work is completed and verified by inspection or photo review.

What if the appraisal comes in low?

The loan amount is limited by the appraised value. You may need to bring more cash, reduce the budget, or adjust the plans. A realistic budget up front helps avoid this.

Can I act as my own builder on a one-time close loan?

Generally no. One-time close programs require a licensed builder who acts as the general contractor under a fixed-price contract and completes builder registration. Owner-builder options are limited to certain investor programs.
