home construction loan interest rates explained for today’s market

How they work

Unlike standard mortgages, construction financing is disbursed in draws, and you usually pay interest-only on money used during the build. Once the home is complete, the loan may convert to a permanent mortgage, or you refinance, which means your true cost combines the build phase rate and the end loan’s terms.

Popular options compared

Here’s how common choices stack up when buyers weigh flexibility versus predictability.

• One-time close: Single underwriting; rate locks early but can price higher for convenience.
• Two-time close: Lower build rate possible; you re-qualify for the end loan, adding risk and fees.
• Fixed during build: Predictable draws; may include a float-down to capture dips.
• Adjustable during build: Tracks prime/SOFR; cheaper upfront, volatile if timelines slip.

What affects your rate

Credit score, loan-to-cost, contingency reserves, builder track record, local supply of funds, and market benchmarks all move pricing. Lender fees and interest-on-draw timing matter as much as the headline APR.

Tips to shop smart

1. Request a draw schedule and per-draw inspection costs in writing.
2. Compare lock length, float-down rules, and conversion fees side by side.
3. Stress-test timelines; budget for delays.
4. Negotiate builder incentives toward points instead of upgrades.
