Construction loan down payment requirements usually start at 20% for conventional loans, drop to 3.5% for FHA loans, and can reach zero for eligible VA and USDA borrowers. Where you land inside those bands depends on your credit score, your debt load, the complexity of the build, and whether you already own the land. Because a construction lender is financing a house that doesn’t exist yet, the equity you bring in cushions the bank against a half-built collateral problem, and that’s why the numbers run higher than on a standard purchase mortgage.
Down Payment by Loan Type
The loan program you use is the single biggest factor in what you’ll owe at closing. Each has its own minimum, its own fees, and its own eligibility rules.
Conventional Construction Loans
Most private lenders require at least 20% down on a conventional construction loan. Some push that to 25% for custom builds with complex engineering or high-end finishes, where cost overruns are more likely. Unlike a standard purchase mortgage where you might put down as little as 3%, construction lenders face the risk of holding a half-built house as collateral if something goes wrong, so they demand more equity upfront.
Credit score decides where you land in that range. Borrowers with scores above 720 and low debt loads tend to qualify at the 20% floor, while scores closer to the mid-600s often trigger a 25% requirement or higher. Most conventional construction lenders set a minimum credit score around 680, though some will go as low as 620 with compensating factors like substantial cash reserves.
FHA Construction Loans
The FHA’s construction-to-permanent loan allows a minimum 3.5% down payment for borrowers with credit scores of 580 or above.1U.S. Department of Housing and Urban Development. Loans If your score falls between 500 and 579, the FHA still allows the loan but bumps the down payment to 10%. The trade-off for that low entry point is mandatory mortgage insurance: an upfront premium of 1.75% of the loan amount, plus ongoing monthly premiums for the life of the loan if you put less than 10% down.
FHA construction loans must go through an FHA-approved lender, and the builder has to meet HUD’s licensing and inspection standards. The program wraps the construction phase and the permanent mortgage into a single closing, which keeps total closing costs lower than financing them separately.
VA Construction Loans
Eligible veterans, active-duty service members, and surviving spouses can finance new construction with zero down payment through the VA’s home loan program.2Veterans Affairs. Funding Fee and Closing Costs Zero down doesn’t mean zero cost at the table. The VA charges a funding fee that varies based on whether you’ve used your VA loan benefit before and how much you put down. For a first-time user making no down payment, the fee is 2.15% of the loan amount. Subsequent use with no down payment jumps to 3.30%. Putting at least 10% down drops the fee to 1.25% for first-time users.3U.S. Department of Veterans Affairs. Funding Fee Schedule for VA Guaranteed Loans
VA construction loans require a VA-registered builder, and the builder must obtain a VA Builder ID number before the project begins.4U.S. Department of Veterans Affairs. Construction and Valuation – VA Home Loans Finding lenders that offer VA construction financing is harder than finding those that offer standard VA purchase loans, so expect a narrower field of options.
USDA Construction Loans
The USDA’s Single Family Housing Guaranteed Loan Program offers 100% financing with no down payment for homes built in eligible rural and suburban areas.5Rural Development. Single Family Housing Guaranteed Loan Program To qualify, your household income cannot exceed 115% of the area’s median income, and the home must be your primary residence. The program has no official minimum credit score, but lenders will expect a reliable payment history. USDA loans are fixed at a 30-year term and carry an upfront guarantee fee plus an annual fee, both typically lower than FHA’s mortgage insurance premiums.
Jumbo Construction Loans
When your project cost exceeds the 2026 conforming loan limit of $832,750, you’re in jumbo territory, and different rules apply.6FHFA. FHFA Announces Conforming Loan Limit Values for 2026 Down payment requirements for jumbo construction loans scale with the loan amount. Loans between $500,000 and $1.25 million may qualify for 10% down with a credit score of 680 or higher. Financing up to $2 million typically requires 20% down, and projects approaching $2.5 million usually need 25%. A credit score below 680 but above 660 can still get approved, but expect to put 15% to 20% down regardless of loan size. Investment properties are generally ineligible for jumbo construction financing.
What Moves Your Number Within a Loan Type
Even inside a single loan program, two borrowers building identical homes can face different down payment requirements. A handful of metrics set the exact figure.
Loan-to-Cost and Loan-to-Value
The loan-to-cost (LTC) ratio compares the loan amount to the total hard and soft costs of the project. The loan-to-value (LTV) ratio compares the loan amount to the appraised value of the finished home. These two numbers rarely match, and the lender typically uses whichever ratio produces the more conservative result. If your total build cost is $500,000 but the completed home appraises at $600,000, the lender may base its calculation on the higher construction cost rather than the lower appraised value, because the cost is what it actually has to fund.
The appraisal itself is done “as-completed,” meaning the appraiser reads your blueprints, specifications, and itemized budget and compares them to recently sold homes with similar features nearby.7Federal Deposit Insurance Corporation. Frequently Asked Questions on Residential Tract Development Lending If that value comes back lower than you expected, your down payment goes up, because the lender will only lend a fixed percentage of the appraised value.
Credit Score and Debt-to-Income
Your credit score and debt-to-income (DTI) ratio work together to set where you land in the range. Fannie Mae’s guidelines cap the DTI at 36% for manually underwritten loans, though borrowers with strong credit scores and adequate reserves can qualify with ratios up to 45%. Loans processed through Fannie Mae’s automated underwriting system can be approved with a DTI as high as 50%.8Fannie Mae. B3-6-02, Debt-to-Income Ratios A borrower with a 750 score and a 30% DTI is going to get the minimum down payment for their loan type. A borrower with a 660 score and a 44% DTI is either getting a higher down payment requirement or a denial letter.
Project Complexity
The design itself changes the risk assessment. A three-bedroom on a flat lot with standard materials is about as safe as construction lending gets. A hillside custom home with structural steel, geotechnical engineering, and imported finishes is a different story. Complex builds are more likely to run over budget and over schedule, so lenders buffer that risk by requiring 25% to 30% down. Unusual homes are also harder for the appraiser to comp, which can compress the LTV ratio and push your down payment higher.
Using Land Equity Instead of Cash
If you already own the lot where you’re building, your equity in that land can serve as part or all of the down payment. The lender determines how much credit you get by subtracting any outstanding liens from the land’s current market value. If the lot appraises at $100,000 and you owe $20,000 on a land loan, you have $80,000 in equity that functions as cash toward the construction down payment. Plenty of borrowers start building without bringing any additional liquid cash to closing, because their land equity meets or exceeds the required percentage.
How the lender values the land depends on how long you’ve owned it. For land held longer than 12 months, most lenders accept the full current appraised value. If you bought the lot recently, the lender often uses the original purchase price plus the cost of any documented improvements, like grading, utility connections, or clearing. This prevents borrowers from relying on short-term market swings to inflate their equity position. Either way, expect the lender to require a standalone land appraisal before approving the construction loan.7Federal Deposit Insurance Corporation.

How the Draw Process Spends Your Down Payment First
Construction loans don’t hand over the full loan amount at closing. Funds are released in a series of draws as the builder completes defined stages of work, and before each draw the lender sends an inspector to verify the work matches what the builder is claiming.
Most lenders require your down payment funds to be spent before any loan proceeds are disbursed. If you put $100,000 down on a $500,000 build, that $100,000 covers the first chunk of construction costs. Only after your equity is exhausted does the lender start releasing its funds. That’s the lender’s way of ensuring you have real skin in the game from day one, not just a promise to contribute later. It also affects timing: the money you bring to closing is gone within the first few weeks of the build, so any additional cash reserves you’re relying on for other expenses need to be genuinely separate.
Other Cash You’ll Need Around Closing
The down payment is the biggest upfront number, but it isn’t the only one. Several other expenses either come out of pocket or get folded into the loan, and knowing about them before you apply prevents surprises at closing.
Contingency Reserves
Lenders set aside a portion of the loan for unexpected cost overruns. FHA 203(k) guidelines, a useful benchmark, require a contingency reserve of 10% to 20% of the financeable construction costs.9FHA Connection Single Family Origination. Standard 203(k) Contingency Reserve Requirements Conventional construction lenders typically require something in the same neighborhood. These funds sit in escrow and can only be released to cover legitimate overruns, not upgrades you decide to add mid-build. Any contingency money left unspent at completion is applied as a principal reduction on the permanent mortgage.
Post-Closing Cash Reserves
Beyond the contingency reserve built into the loan, lenders want to see that you still have liquid assets after closing. The USDA’s construction-to-permanent program allows lenders to fund a reserve account covering up to 12 months of principal, interest, taxes, and insurance (PITI) during the construction period.10eCFR. Subpart C Loan Requirements Conventional lenders commonly want to see two to six months of PITI in liquid reserves after closing, depending on the loan amount and your credit profile. These reserves prove you can absorb unexpected costs without defaulting.
Permits, Impact Fees, and Documenting Your Funds
Building permits for residential construction range widely depending on your jurisdiction and the project’s valuation. Some municipalities charge a flat fee; others base the cost on a per-thousand-dollar rate applied to the construction value. Impact fees, which fund infrastructure like roads, schools, and sewer connections, can add thousands more in certain areas. These are typically paid before construction begins and can sometimes be rolled into the construction loan, but you’ll need to confirm with your lender whether they count as eligible project costs or must come out of pocket.
Whatever you’re bringing to closing, expect to prove where it came from. Lenders require at least two months of consecutive bank statements showing the source of your down payment funds. Large deposits that appear during that window need paper trails, whether they came from selling investments, a 401(k) loan, or a gift. The point is proving the money is seasoned and doesn’t represent an undisclosed personal loan that would inflate your actual debt load.
