How Construction Loans Work: The Complete Guide (2026)

What Is a Construction Loan?

A construction loan is short-term financing designed specifically to fund the building of a new home. Unlike a standard mortgage — where a finished property serves as collateral from day one — a construction loan is secured by a project that does not yet exist. That fundamental difference shapes everything about how these loans work: the approval process, the disbursement structure, the payment schedule, and the eventual conversion to a permanent mortgage.

Because the lender is financing an unbuilt home, they evaluate both the borrower and the project itself. Your credit profile, income stability, and debt load carry more weight than in a conventional purchase. The lender also reviews your builder's qualifications, the construction plans, and a detailed budget before approving the loan. This dual evaluation is why construction loans typically require stronger borrower credentials and more documentation than a standard mortgage.

Construction loans are typically structured as 12-month terms (though 18- and 24-month terms are available for larger projects), with variable interest rates during the build phase. Rates generally run higher than conventional mortgage rates — reflecting the increased risk to the lender — though the exact spread varies by lender, program, and market conditions. See current construction loan rates for today's estimated figures.

How the Draw Schedule & Interest-Only Payments Work

The draw schedule is the mechanism that controls how construction loan funds are released. Rather than receiving the full loan amount at closing, your lender holds the approved funds in escrow and disburses them in stages as construction progresses. Each disbursement — called a "draw" — is tied to a specific construction milestone.

Before each draw is released, the lender typically sends an inspector to verify that the milestone work has been completed to the required standard. This inspection process protects both parties: the lender confirms their collateral is being built correctly, and you confirm that your builder is completing work before receiving payment.

A typical five-draw schedule might look like this:

• Draw 1 — Foundation (15–20% of loan): Released after site work, excavation, and foundation pour are complete and inspected.
• Draw 2 — Framing (20–25%): Released after structural framing, roof sheathing, and exterior sheathing are complete.
• Draw 3 — Mechanical rough-in (20%): Released after plumbing, electrical, and HVAC rough-in pass inspection.
• Draw 4 — Interior finish (20–25%): Released after drywall, insulation, cabinets, flooring, and interior trim are installed.
• Draw 5 — Completion (10–20%): Released after final inspection and certificate of occupancy is issued.

During construction, you make interest-only payments on the funds that have been disbursed — not the full loan amount. Early in the build, when only the foundation draw has been released, your monthly payment is relatively small. As more draws are released and more of the total loan is outstanding, your interest payment increases proportionally.

Construction-to-Permanent vs. Two-Time Close

There are two primary structures for construction financing, and the choice between them affects your closing costs, rate flexibility, and administrative burden.

Construction-to-Permanent (One-Time Close)

A construction-to-permanent loan covers both the construction phase and the permanent mortgage in a single closing. You qualify once, pay one set of closing costs, and your construction loan automatically converts to a permanent mortgage (typically a 30-year fixed) when the home is complete. This is the most common structure for borrowers who want simplicity and rate certainty. Read the full one-time-close guide for details on how the conversion works.

Stand-Alone Construction Loan (Two-Time Close)

A stand-alone construction loan covers only the build period. When construction is complete, you apply for and close on a separate permanent mortgage. This means two qualification processes and two sets of closing costs — but it gives you the flexibility to shop for the best permanent rate once your home is finished and market conditions may have changed. Some borrowers prefer this structure when they expect rates to drop during their build timeline.

Using Land You Already Own as Your Down Payment

If you already own the lot where you plan to build, most construction lenders will count your land equity toward the required down payment or equity contribution. This is one of the most significant advantages for borrowers who purchased their land separately or inherited it.

For example, if your total project cost (land + construction) is $500,000 and the lender requires a 20% equity contribution ($100,000), owning a lot appraised at $100,000 or more could satisfy the entire requirement — meaning no additional cash down payment beyond closing costs. The land must typically be owned free and clear or have minimal remaining debt, and the lender will require a current appraisal to establish its value.

If you haven't purchased land yet, a lot loan can help you acquire it before you're ready to build. Some lenders offer combined lot-and-construction financing that rolls the land purchase into the construction loan.

What You Need to Qualify

Construction loan qualification is more involved than a standard mortgage because the lender is evaluating both you and an unbuilt project. While specific requirements vary by lender and program, here is what most lenders look for:

• Credit profile: Most conventional construction lenders look for credit scores in the mid-to-upper range, though government-backed programs (FHA, VA, USDA) may accept lower scores. The exact threshold varies by lender.
• Down payment or equity: Conventional construction loans typically require a larger equity contribution than a standard purchase mortgage. Government-backed programs often allow lower down payments — VA construction loans may require zero down for eligible veterans.
• Debt-to-income ratio: Lenders evaluate your total monthly debt obligations relative to your gross income. Construction loans may use the projected permanent payment (not the lower interest-only payment) for qualification purposes.
• Licensed builder: Most lenders require a licensed, insured general contractor with a track record of completed projects. Owner-builder programs exist but are less common and typically require demonstrated construction experience.
• Detailed plans and budget: Complete architectural plans, specifications, and a line-item construction budget are required. The lender uses these to establish the as-completed appraised value.

Government-Backed Construction Loan Programs

Several federal programs make construction loans more accessible by reducing down payment requirements, accepting lower credit scores, or offering favorable terms for specific populations:

• FHA Construction Loans — Lower down payment and credit requirements, insured by the Federal Housing Administration. Available as one-time-close.
• VA Construction Loans — Zero-down construction financing for eligible veterans, active-duty service members, and surviving spouses. Guaranteed by the Department of Veterans Affairs.
• USDA Construction Loans — Zero-down option for eligible properties in USDA-designated rural areas. Income limits apply.
• HUD Section 184 — Construction financing for Native American and Alaska Native borrowers on trust or fee-simple land.

Each program has distinct eligibility criteria and loan limits. Visit the individual program pages for detailed requirements, or get matched with a specialist who handles your specific program.
