Construction Loans Explained: Types, Rates, and Lender Requirements

A construction loan pays for building or renovating a home in stages, releasing money as work gets done instead of handing over one lump sum at closing like a traditional mortgage. Because the lender is financing something that doesn’t exist yet, the underwriting process looks different, the rates run higher, and the paperwork requirements are heavier. Understanding how these loans work before you talk to a lender saves weeks of back and forth and can keep your project from stalling mid-build.

How a Construction Loan Differs From a Regular Mortgage

A standard mortgage is secured by a finished, appraised property. A construction loan is secured by a piece of dirt, a set of blueprints, and a builder’s contract. Lenders can’t simply compare your project to three recent sales down the street, because there’s nothing standing yet. Instead, they underwrite the land, the plans, the builder, and you, all at once.

Money is released in a series of draws tied to completed work: foundation poured, framing up, roof on, drywall hung, and so on. An inspector or appraiser typically confirms each stage before the lender releases the next payment. Interest during construction is usually charged only on the amount drawn so far, not on the full loan amount, which keeps monthly payments lower during the build phase.

Main Types of Construction Loans

Most borrowers choose from a handful of structures, and the right one depends on whether you’re building new, renovating, or acting as your own general contractor.

Construction-to-permanent loan: One loan covers the build and then converts automatically into a standard mortgage once the certificate of occupancy is issued. You close once, pay one set of closing costs, and lock a rate either at the start or after conversion depending on the lender’s terms.
Stand-alone construction loan: A short-term loan (usually 6 to 18 months) that covers only the build. Once construction finishes, you refinance into a separate permanent mortgage. This means two closings and two sets of closing costs, but it gives you flexibility to shop rates again after the home is done.
Owner-builder loan: For borrowers who plan to act as their own general contractor rather than hiring one. Lenders approve these far less often and usually require proof of construction experience or a licensed contractor’s background.
Renovation loans (including FHA 203(k) and conventional rehab products): Built for buyers purchasing a fixer-upper or homeowners doing a major remodel. The loan wraps the purchase price (or existing mortgage balance) and renovation costs into a single loan amount based on the projected after-repair value.

What Rates and Costs Actually Look Like

Construction loan rates typically run 0.5 to 1.5 percentage points higher than a comparable fixed-rate mortgage, and most are variable during the build, often tied to the prime rate plus a margin (for example, prime plus 1%). A borrower might see a construction-phase rate around 8% to 9% in a market where standard 30-year mortgage rates sit near 6.5% to 7%, though exact numbers shift with the broader rate environment.

Expect these additional costs beyond the interest rate:

An origination or construction fee, often 0.5% to 1% of the loan amount
Draw inspection fees, usually $150 to $500 per site visit, charged each time an inspector confirms a construction stage
A contingency reserve, commonly 5% to 10% of the total construction budget, held back in case of cost overruns
Appraisal fees for both the projected “as-completed” value and, in some cases, a second appraisal near the end of the build

Down payment requirements are also steeper than a typical mortgage. Where a conventional home purchase might allow 5% to 20% down, construction loans commonly require 20% to 25%, and sometimes more if the borrower is acting as an owner-builder or building a highly custom home that’s harder to appraise.

What Lenders Actually Look For

Approval hinges on more than your income and credit score, though those still matter. Most lenders want to see a credit score of 680 or higher for a construction loan, compared with scores as low as 620 accepted on some standard mortgage products. Debt-to-income ratio limits are usually similar to conventional loans, generally capped around 43% to 45%.

Beyond the numbers, lenders scrutinize the project itself:

Detailed plans and specifications: Full architectural drawings, a materials list, and a line-item construction budget, not a rough sketch and a guess at total cost.
A signed, fixed-price contract with a licensed, insured builder: Lenders often require the builder to carry general liability insurance and provide references or proof of past completed projects.
Builder financials and license verification: Some lenders run a background check on the contractor’s licensing status and check for liens or unresolved complaints.
An “as-completed” appraisal: An appraiser estimates what the home will be worth once finished, based on the plans and comparable newly built homes nearby.
Proof of funds for the down payment and reserves: Lenders typically want to see enough liquid reserves to cover several months of payments after the loan converts to permanent financing.

Land ownership status matters too. If you already own the lot free and clear, that equity can often count toward your down payment. If you’re purchasing the land as part of the loan, expect the lender to underwrite the land value separately from the construction budget.

Managing the Draw Schedule and Avoiding Delays

Once the loan closes, funding follows a draw schedule agreed upon in advance, typically five to ten draws tied to milestones like site work, foundation, framing, mechanical rough-in, drywall, and final finishes. Before releasing each draw, the lender sends an inspector to confirm the work matches what was billed. Delays at this stage are common and usually come from incomplete paperwork, unexpected code issues, or a builder falling behind schedule.

Borrowers can keep the process moving by requesting lien waivers from subcontractors after each payment, keeping receipts and invoices organized by draw stage, and staying in direct contact with the builder about inspection scheduling rather than assuming the lender and builder are coordinating automatically.

Before applying, request a sample draw schedule and full fee disclosure from at least two or three lenders, then compare the total cost of construction-to-permanent versus stand-alone options side by side using your actual budget numbers. That comparison, done on paper before you sign anything, is what determines whether the loan structure fits your project or fights it.
