Conventional One-Time Close Loans in Florida

You do not need a VA benefit to explore building a home with construction and permanent financing arranged together. A conventional one-time close construction loan is another route. But the borrower, land, builder, and project all have to fit.

If you are planning a custom home around Orlando or elsewhere in Florida, I would start with those pieces before you commit to a lot or a large builder deposit. A preliminary mortgage conversation is not project approval.

What One-Time Close Actually Means

The construction financing and permanent mortgage are established in one coordinated closing. Money is released through an approved draw process during construction. After completion and the required modification, the loan enters its permanent repayment phase.^[1] One closing does not mean one document, no construction fees, or no further review.

Fannie Mae's single-closing framework allows construction and permanent financing to be arranged together, with the lender managing disbursements. Its rules distinguish purchasing the lot from building on land already owned, and applicable property matrices still control eligibility. That agency framework does not mean every lender offers the product.^[2]

The details below come primarily from a participating wholesale investor program guide reviewed October 20, 2026. They are lender-specific program requirements, not universal conventional rules. The guide displays no revision date. Current availability and file-specific requirements need confirmation. The participating lender and required disclosures will be identified during an actual transaction.

The Conventional Structures in the Reviewed Guide

Permanent financing: Fixed-rate and adjustable-rate mortgage options, subject to current program availability and file review.
Automated underwriting: Fannie Mae Desktop Underwriter, or DU, must return Approve/Eligible; Freddie Mac Loan Product Advisor, or LPA, must return Accept/Eligible.
Loan size: Conforming and high-balance limits. A loan above the standard conforming baseline is not automatically jumbo. County, unit count, and the available product route need review.
Occupancy: Primary residences, second homes, and investment properties appear in the guide, subject to the applicable borrower, property, and occupancy matrix.
Financing ceiling: Up to 95% LTV/CLTV/HCLTV is the guide's overall maximum, not a promise for every occupancy, property type, or unit count.

LTV compares the mortgage with the applicable property value. CLTV and HCLTV also account for other secured financing and, where applicable, a home equity line's credit limit. Your required contribution depends on your specific property and loan structure. Your actual financing limit can be lower, and cash to close also involves costs and prepaid expenses. The guide flags declining or risky markets for possible additional restrictions.^[1]

Credit needs its own review. I would check the score, recent installment-loan late payments, full credit history, AUS result, any mortgage-insurance requirements, and the current program overlay before discussing eligibility. A score by itself is not an approval, and this article does not advertise a universal minimum or a no-minimum-score program.

Buying the Lot Versus Building on Land You Own

If you buy the lot at closing: The reviewed program treats that as a purchase structure. The initial disbursement can include the land purchase and approved construction funds. The land contract and construction budget need to fit the same financing plan.^[1]

If you already own the land: The guide places that in its construction-refinance route. If there is an existing lot loan, its payoff must be part of the review. Owning the land free and clear does not turn the file into a lot purchase simply because you have not built the house yet.

Land equity and cash are different. The guide says land is included in the appraised property value and can lower the financing ratio, but its value is not cash available to pay your closing costs. I would review title ownership, acquisition history, liens, the proposed completed value, and the construction budget before estimating the funds you need.

Do not move title around to try to force a financing category. Have the lender and title professionals review the existing ownership structure first. This article is not advice to transfer land to a builder or change legal ownership.

You Make Interest-Only Payments During Construction

Under the reviewed conventional structure, construction-period payments are interest-only and based on the amount actually drawn, not automatically the entire approved loan amount. As additional loan funds are drawn, the interest due generally increases. Ask for a draw-based cash-flow explanation rather than relying on a single average estimate.^[1]

Once construction and modification are complete, principal-and-interest repayment begins. The full permanent repayment term starts at modification; construction months are not subtracted from that term under this structure.

I would build a separate household budget for construction interest, your current housing, and expenses outside the loan. The guide requires your current mortgage payment in qualification unless you sell that residence before closing to exclude it. Future income you expect to earn cannot simply be added to make the file work.

For veterans comparing routes, see the VA one-time close construction companion. Construction payments and other requirements differ, so we should review each option separately.

The Build Budget Needs More Than the Contract Price

The reviewed program requires a contingency equal to 5% of construction costs in the project budget. That is a construction-cost reserve, not a down-payment percentage. It is included in the initial loan amount to address underestimated construction costs. Unused contingency funds reduce the borrower's principal balance; they are not described as a cash refund.^[1]

A contingency does not make overruns disappear. The guide says the borrower may need to provide additional money if completion costs exceed the budget and available contingency. Before approving an upgrade, ask who pays, whether the contract and budget need amendment, and whether the lender needs to review the change.

Request an itemized explanation of project review, draw, inspection, appraisal, title, and completion costs. Ask which charges appear in closing disclosures, which belong in the construction budget, and when they are collected. One closing is not a promise that these services are free.

Keep documented construction prepayments separate from deposits and other credits. Paid invoices and proof of the source of funds matter. A builder's worksheet alone should not be treated as proof that you will receive a credit, and the same deposit cannot reduce cash to close twice.

The Builder and Project Need Separate Approval

Borrower approval does not approve the builder. The reviewed program requires a contractor package that includes licensing, insurance or an applicable workers' compensation exemption, and business documentation. A builder's prior relationship with a lender does not replace approval for your file.^[1]

The project package needs a signed construction contract, a matching cost breakdown, full plans and specifications, permit information, and documented prepayments where applicable. The construction contract and budget totals must agree. The lender orders a full appraisal based on the proposed completed home, not just the vacant lot.

For an Orlando-area project, I would ask the builder to identify what is included for site preparation, utilities, drainage, and permitting. Those are budget questions to resolve, not promises that any particular expense is financeable.

If work has started, tell me the exact stage before authorizing more. The construction desk must confirm whether your project can use this program.

Property Type and Owner-Builder Limits Matter

The guide lists modular and manufactured homes and permits consideration of certain unique properties when acceptable comparable sales support the appraisal. Its broad property parameters allow up to four units, but that does not make every property-and-occupancy combination available. Applicable agency, investor, appraisal, and property-specific requirements still apply.^[1]

A barndominium plan, factory-built delivery schedule, or unusual design needs early review. Factory-built homes use a different draw process, so the manufacturer's deposit requirements must be reconciled with lender requirements before you commit.

Attached condominiums, cooperatives, and temporary buydowns are ineligible under the reviewed product. Owner-builders are considered only for conventional primary residences in this guide, not automatically approved. Borrower affiliation with the builder also requires review. Do not assume an owner-builder exception applies to second homes, investments, or VA financing.

Insurance, Taxes, and Escrows Need a Construction Plan

The conventional program waives the tax-and-insurance escrow account during construction and establishes it at modification. That does not waive the underlying bills. Ask who pays each expense during the build and when funds must be available.^[1]

The guide requires builder's risk coverage or an acceptable construction endorsement effective at closing. It also calls for a completed-home insurance quote when builder's risk is used. Have the insurance professional and lender coordinate the construction and permanent coverage, effective dates, and payer. Do not count the same premium twice or assume a vacant-land policy covers the build.

Tax planning must reflect land and improvements, not just the current vacant-lot bill. For related planning questions, read Florida homeowners insurance and mortgage approval and Florida mortgage reserves. Required reserves and money you personally want left after closing are separate conversations.

Completion Is a Deadline, Not Just a Move-In Date

The guide allows an 11-month maximum build period followed by a one-month modification period. It requires the modification agreement to be signed within 12 months of closing; otherwise, requalification is required. The guide also says a build taking longer than 11 months requires requalification. A delayed build needs immediate review rather than an assumption that the original approval lasts indefinitely.^[1]

Completion involves the required appraisal update and/or completion report, Form 1004D, the certificate of occupancy before signing the modification package, and the lender's final documentation. The final draw is held until the modification agreement is signed. Moving into the house is not a substitute for completing that process.

There may be an optional float-down opportunity at modification if the lender's current conditions are met. Do not budget on receiving one. Request the actual written terms and eligibility review. One-time close does not guarantee a lower final rate, no updated documents, or no re-underwriting. For loans following Fannie Mae rules, modified terms outside applicable tolerances, a falling appraised value that raises LTV, or required updated credit documents can trigger requalification. Missing the lender's deadline is not the only trigger.^[2]

Start With a Conventional Build-Ready Review

My starting review covers borrower qualification, land structure, builder readiness, contract and budget, and construction stage. Send general project facts first: Florida county; whether the lot is being purchased or already owned; who holds title and whether there are liens; intended occupancy, unit count, and property type; builder name; estimated budget; expected timeline; and work already completed.

Use the contact form for that initial outline or the application page when you are ready to begin the formal process. Do not send Social Security numbers, account statements, or other sensitive documents in a general message. We can identify the appropriate document-submission process after the initial conversation.

This is general mortgage education, not individualized financial, legal, tax, or final underwriting advice. Guidelines and lender availability can change. Consult your loan officer for current requirements. Eligibility, approval, construction completion, closing dates, and funding are not guaranteed.
