Construction Loans: Financing New Home Builds
Construction loans occupy a distinct segment of the mortgage market, structured to fund the phased costs of building a residential structure rather than purchasing an existing property. Unlike conventional mortgages, these instruments disburse funds incrementally as construction progresses, carrying different underwriting standards, draw schedules, and conversion mechanisms. Understanding how this financing category is structured — and where it sits within the broader mortgage landscape — is essential for borrowers, builders, and real estate professionals navigating new residential development.
Definition and scope
A construction loan is a short-term credit facility used to finance the labor, materials, and related costs of building a new home from the ground up. The Consumer Financial Protection Bureau (CFPB) classifies construction-purpose loans as a distinct origination category under the Home Mortgage Disclosure Act (HMDA) reporting framework, separate from home purchase and refinance loans.
The defining characteristic is the draw structure: rather than receiving a lump sum at closing, the borrower (or their builder) draws funds against the loan commitment at predetermined construction milestones. The loan term is typically 6 to 18 months, after which the balance is either repaid in full or converted to a permanent mortgage. Interest during the construction phase accrues only on funds drawn, not on the full committed amount.
Construction loans fall under Regulation Z (Truth in Lending Act) administered by the CFPB, which governs disclosure requirements. For federally chartered lenders, the Office of the Comptroller of the Currency (OCC) and the Federal Reserve set capital and appraisal standards applicable to these products under 12 CFR Part 34 and interagency appraisal guidelines.
How it works
The construction loan process follows a defined sequence with clear decision points at each phase:
-
Pre-qualification and underwriting: The lender evaluates the borrower's creditworthiness, the builder's credentials (license, insurance, track record), and the proposed project plans. A licensed appraiser performs an "as-completed" appraisal estimating the property's value upon project completion — this figure caps the loan amount.
-
Loan commitment and closing: At closing, the borrower signs the full loan agreement. No funds are disbursed at this stage for construction costs. A construction escrow account is established to hold the committed loan proceeds.
-
Draw schedule establishment: The lender and borrower agree on a draw schedule, typically tied to 4 to 6 construction milestones (foundation completion, framing, mechanical rough-in, drywall, substantial completion, final walkthrough). Each draw request triggers an inspection by a bank-designated inspector or appraiser.
-
Construction phase disbursements: As each milestone is verified, the lender releases the corresponding draw to the builder or contractor. Interest accrues on the outstanding drawn balance at a variable rate, commonly pegged to the Wall Street Journal Prime Rate plus a margin.
-
Construction completion and transition: Upon issuance of a certificate of occupancy by the local building authority, the construction phase ends. The borrower either pays off the balance (often through a separately arranged take-out mortgage) or triggers a conversion to permanent financing.
Lenders typically require a 20% down payment based on the total project cost (land plus construction), though programs backed by the Federal Housing Administration (FHA) — specifically the FHA 203(k) and the One-Time Close construction program under HUD Handbook 4000.1 — permit lower down payments for qualifying borrowers. The Department of Veterans Affairs (VA) also offers a construction-to-permanent option for eligible service members (VA Lenders Handbook, Chapter 6).
Common scenarios
Three primary use cases define the construction loan market:
Owner-builder construction: The borrower acts as their own general contractor. Lenders apply stricter scrutiny in this scenario — most conventional lenders require demonstrated construction management experience, and loan availability is narrower. These arrangements are documented under state contractor licensing law, which varies by jurisdiction.
Builder-financed spec construction (third-party build): A licensed general contractor manages the project under a fixed-price or cost-plus contract. This is the most common residential construction scenario and presents the most straightforward underwriting path for lenders.
Lot acquisition and construction: When the borrower does not yet own the land, the loan commitment covers both land purchase and construction costs. Land value typically cannot exceed 25–30% of the total loan amount under standard lender guidelines, though this threshold is not universally codified.

Decision boundaries
The choice between a two-close construction loan and a one-time close (OTC) construction-to-permanent loan is the primary structural decision in this financing category.
| Feature | Two-Close | One-Time Close |
|---|---|---|
| Closings | 2 (construction + permanent) | 1 |
| Closing costs | Paid twice | Paid once |
| Rate lock | Permanent rate set at second close | Rate locked at initial close |
| Flexibility | Can shop permanent lender separately | Permanent terms fixed at outset |
| Common programs | Conventional, jumbo | FHA, VA, USDA, some conventional |
Two-close structures offer rate flexibility but expose the borrower to interest rate risk between closings. One-time close structures eliminate that risk but lock in permanent terms before the home's final appraised value is established.
Loan sizing is also subject to conforming loan limits published annually by the Federal Housing Finance Agency (FHFA) (FHFA Conforming Loan Limits). As of the FHFA's 2024 announcement, the baseline conforming limit for single-unit properties is $766,550, with higher-cost area ceilings reaching $1,149,825 — figures that directly affect whether a construction loan can be originated as a conforming product.
