Quick Answer
Most construction loans require 10% to 25% down, with many lenders expecting around 20% due to higher project risk.
Unlike a mortgage on an existing home, a construction loan is based on a home that has not been built yet — which means more risk for the lender and typically a larger down payment requirement for you. The exact amount depends on loan type, whether you already own the land, your credit profile, and how the lender calculates your loan amount.
Borrowers with strong credit, stable income, or existing land equity often qualify for the lower end of the range, while first-time builders or those with thinner credit profiles should expect to land closer to 25%.
Down Payment by Loan Type
Typical ranges vary significantly depending on which construction loan program you use.
| Loan Type | Typical Down Payment | Notes |
|---|---|---|
| Conventional construction loan | 20% – 25% | Most common for owner-occupied new builds. Down payment is based on total project cost — land plus construction — not just the structure. |
| Construction-to-permanent loan | 15% – 25% | One closing covers both the build phase and the permanent mortgage. Down payment requirements are similar to a standalone construction loan. |
| Stand-alone construction loan | 20% – 30% | Requires a separate closing to convert to a permanent mortgage after completion, which usually means stricter down payment requirements. |
| VA construction loan | 0% | Available to eligible veterans and active-duty service members. No down payment required, but the builder must be VA-approved. |
| USDA construction loan | 0% | Available for eligible rural properties and qualifying income levels. No down payment required if the property and borrower meet program criteria. |
| FHA construction loan | 3.5% | Lower down payment option for qualifying borrowers, but comes with mortgage insurance requirements and stricter builder qualification rules. |
Before You Talk to a Lender
Know your real build cost before estimating your down payment
Lenders size your down payment off total project cost — land, construction, and contingency. A rough guess leads to a rough down payment estimate.
What Affects Your Down Payment Amount
These six factors drive how much cash a lender will actually require from you.
If you already own the land free and clear, its appraised value can often count toward your required down payment — sometimes covering it entirely. If you are purchasing land as part of the project, lenders typically require 20% to 50% down on the land portion specifically.
Most construction lenders look for a credit score of 680 or higher. Stronger credit (740+) can sometimes unlock lower down payment options or better interest rates during the build phase.
Lenders may base your loan on total project cost (loan-to-cost) or on the appraised value of the completed home (loan-to-value). If the home appraises higher than the build cost, a loan-to-value structure can sometimes reduce the cash you need upfront.
Most lenders require a licensed, insured builder with a track record before approving a construction loan. Working with an unproven or owner-builder arrangement can increase down payment requirements or disqualify certain loan programs entirely.
Lenders generally want total debt obligations to stay under 45% of monthly income. A higher DTI can mean a larger required down payment to offset perceived risk.
Detailed plans, a fixed-price contract, and a realistic contingency budget (typically 10-15% of cost) all factor into how a lender assesses risk — and risk assessment directly affects the down payment they require.
Land Equity Can Cover Your Entire Down Payment
If you already own your lot free and clear, its appraised value typically counts toward your required down payment — and in some cases, can cover it completely. For example, on a $500,000 total project with a 20% down payment requirement ($100,000), land worth $100,000 or more with no mortgage against it may satisfy the entire requirement.
If your land still has a mortgage, only your equity in it — the value minus what you owe — typically counts toward the down payment.

Before talking to a lender, know your actual project cost — land, construction, permits, and a contingency buffer. Lenders size your down payment off total project cost, not a rough guess.
If you own land already, get a current appraisal or assessed value. This can be applied toward your down payment requirement and may reduce or eliminate the cash you need to bring.
Not all mortgage lenders offer construction loans. Look specifically for lenders experienced in construction-to-permanent or stand-alone construction financing.
Ask each lender how they calculate your loan amount. A loan based on completed appraised value, rather than just cost, can sometimes lower your required down payment.
Many lenders require your builder to be pre-approved or meet specific licensing and insurance criteria before they finalize your down payment terms.

Frequently Asked Questions
What is the minimum down payment for a construction loan?
The minimum is typically 10% to 20% for conventional construction loans, though most lenders expect around 20% to 25% due to higher project risk. VA and USDA construction loans can offer 0% down for qualifying borrowers, and FHA construction loans may allow as little as 3.5% down.
Does owning my land count toward the down payment?
Yes, in most cases. If you own the land free and clear, its appraised value typically counts toward your required down payment and can sometimes cover it entirely. If there is a mortgage on the land, only your equity in it usually counts.
Is a construction loan down payment based on total project cost or just the home?
Most lenders calculate the down payment based on total project cost — land plus construction — rather than just the structure. This is one reason construction loan down payments are often higher than a typical home purchase down payment.
Can I reduce my construction loan down payment?
Strategies include applying land equity toward the down payment, exploring VA or USDA programs if eligible, choosing a lender that bases the loan on completed appraised value rather than cost, and improving your credit score before applying.
Do construction loans require more cash upfront than a regular mortgage?
Generally yes. Because the home does not exist yet, lenders see construction loans as higher risk and typically require larger down payments (often 20%+) compared to a conventional mortgage on an existing home.
What other upfront costs should I budget for besides the down payment?
Beyond the down payment, budget for draw inspection fees (typically $100-$150 per inspection), a construction administration or builder's risk fee ($500-$1,500), closing costs, and your contingency reserve for unexpected costs during the build.
