How much down payment do I need for a construction loan?

    By Updated September 2026

    A construction loan typically requires equity of 20 to 35 percent of total project cost, meaning land plus hard and soft costs, with experienced borrowers at the low end and first projects at the high end. Land you already own counts toward that equity at purchase price or appraised value, which can reduce the cash required to little or nothing.

    How the number is calculated

    Lenders size the loan as a percentage of total cost, capped by a percentage of completed value. Your equity is the difference between total cost and the loan.

    Borrower profileTypical loan-to-costEquity required
    Experienced, bank lender75 to 85 percent15 to 25 percent
    Experienced, private lender80 to 85 percent15 to 20 percent
    First project, private lender65 to 75 percent25 to 35 percent
    Speculative or unusual asset60 to 70 percent30 to 40 percent

    Ranges vary by lender.

    A worked example

    Total cost $1.5 million (land $300,000, hard costs $1,050,000, soft costs and interest reserve $150,000). At 75 percent loan-to-cost the loan is $1,125,000 and your equity is $375,000. If you own the land free and clear and it appraises at $300,000, that equity covers $300,000, and you bring $75,000 in cash plus closing costs. If you are buying the land as part of the project, you bring the full $375,000.

    What counts as equity

    • Cash at closing.
    • Land you own, at purchase price if bought within about a year, or appraised value if held longer or entitled since.
    • Prepaid soft costs, such as plans, permits, and engineering already paid, when documented.
    • Sweat equity: generally not counted.
    • Seller financing on the land: rarely allowed to sit behind a construction loan; ask first.

    Reserves on top of equity

    Separate from the equity, lenders want reserves after closing, typically 10 to 15 percent of the loan amount. On a $1,125,000 loan that is $112,000 to $170,000 in verified funds. This is the number that surprises first-time developers.

    The completed-value cap

    Even with enough equity, the loan cannot exceed 60 to 75 percent of the as-completed appraised value. If the project cost is high relative to the finished value, the lender reduces the loan and the equity requirement rises. A project that costs $1.5 million and appraises at $1.7 million finished is at the edge for many lenders.

    Lowering the cash requirement

    1. Use land you already own.
    2. Bring an experienced partner or contractor to move to a lower equity tier.
    3. Reduce scope to what the appraisal supports.
    4. Document prepaid soft costs.
    5. Choose a lender whose grid fits your profile rather than the first bank to say 35 percent.
