What interest rate do construction loans charge?

    By Updated September 2026

    Construction loans typically charge prime plus 1 to 2.5 percent at banks and 9 to 13 percent at private lenders, always interest-only and usually only on the funds drawn so far, plus one to three points at closing. Because the balance grows through the build, the effective interest over a twelve-month project is roughly half of what the full loan would cost for a year.

    Ranges vary by lender and move with the index.

    Interest on drawn funds

    Interest accrues on the amount advanced to date, not the full commitment. On a $1.2 million loan drawn evenly over twelve months at 11 percent, total interest is about $66,000 rather than $132,000. The interest reserve is sized on that curve, which is why it is smaller than a flat calculation suggests.

    The interest reserve

    Most construction lenders fund an interest reserve from the loan so you do not make payments from cash during the build. It is sized for the construction period plus lease-up and is itself part of the loan, so it accrues interest. When it runs out, payments come from your pocket.

    What moves the rate

    • Leverage. 65 percent of cost prices lower than 85 percent.
    • Experience. A completed comparable project is the biggest discount.
    • Asset type. Single-family and small multifamily price lowest; hospitality, special-purpose, and land-heavy projects price highest.
    • Pre-leasing or pre-sales. Signed leases or contracts lower the risk and the rate.
    • Recourse. Full personal guarantees price lower than limited recourse.

    Fees beyond the rate

    • Draw inspection fees: $150 to $400 per draw.
    • Budget and plan review: $1,000 to $3,000.
    • Appraisal with as-completed value: $2,000 to $5,000.
    • Extension: a half to one point if the build runs long.
    • Legal: higher than a permanent loan because of the construction agreements.

    A worked example

    $1.2 million private construction loan, 11 percent, two points, twelve-month build with even draws, then a two-month lease-up before refinance:

    • Interest during build: about $66,000
    • Interest during lease-up on the full balance: about $22,000
    • Points: $24,000
    • Inspections, review, appraisal: about $8,000
    • Total: about $120,000, or 10 percent of the loan over fourteen months
