Construction loans typically require a down payment of 20 to 25 percent, though some lenders accept 10 to 15 percent depending on the project type and your financial profile

A construction loan finances the building process itself, not the finished home. The lender disburses money in stages as work progresses, rather than handing over a lump sum at closing. Because the lender is funding an asset that doesn't yet exist, they treat down payments differently than a traditional mortgage does.

The down payment on a construction loan covers your equity stake in the land and the project. You pay it upfront, before construction begins. The lender then finances the remaining cost of land acquisition, materials, labor, and permits. If you're building on land you already own, your down payment may be smaller because the lender's risk is lower—you've already paid for the collateral.

Construction loans are short-term, usually 12 to 24 months. Once the home is finished, you refinance into a permanent mortgage. That permanent mortgage may have its own down payment requirement, though many lenders credit the construction loan down payment toward it.

Key Takeaways

  • Construction loans require 10 to 25 percent down, with 20 percent being the most common threshold across major lenders.
  • If you own the land outright, some lenders reduce the down payment requirement because your equity is already in place.
  • The down payment is drawn at closing, before construction starts, and covers your ownership stake in the project.
  • When construction ends, you refinance into a standard mortgage, which may have a separate down payment or may roll the construction loan down payment into the new loan.
  • Construction loans are riskier for lenders than mortgages on finished homes, which is why down payments tend to be higher.

How construction lenders calculate your down payment requirement

Construction lenders look at the total project cost, which includes land, labor, materials, permits, and contingencies. They then determine what percentage you must cover out of pocket. A 20 percent down payment on a $400,000 project means you pay $80,000 upfront.

The lender's decision also depends on your credit score, debt-to-income ratio, and whether you're an experienced builder or a first-time homeowner. Borrowers with strong credit and low existing debt may may have access to for 10 to 15 percent down. Those with weaker profiles or no building experience often face 25 percent or higher.

If you're buying land and building on it, the lender may require you to pay for the land in full or put down a substantial amount before they'll finance construction. Some lenders treat land acquisition and construction as separate loans with separate down payments. Others bundle them into one construction loan with a single down payment covering both.

Down payment differences between owner-builders and contractors

If you're the owner-builder—meaning you're managing the project yourself rather than hiring a general contractor—lenders often require a higher down payment. They view owner-builders as higher risk because they lack the professional liability insurance and track record of a licensed contractor. Expect 20 to 25 percent down in this scenario.

If you hire a licensed general contractor with a solid reputation and insurance, lenders may accept 15 to 20 percent down. The contractor's experience and bonding reduce the lender's perceived risk. Some lenders offer slightly better terms if the contractor has worked with them before.

Spec builders—companies that build homes on speculation to sell later—often negotiate lower down payments with lenders because they have established relationships and a history of completed projects. First-time builders rarely get this advantage.

What happens to your down payment during construction

Your down payment sits in an escrow account held by the lender or a title company. It is not spent immediately. Instead, the lender disburses construction funds in draws, usually tied to completion milestones: foundation poured, framing complete, roof on, interior finished, and so on.

Each draw request requires inspection and approval from the lender's inspector or the general contractor. The lender pays the contractor or suppliers directly from the construction loan funds. Your down payment remains in reserve as a cushion for the lender. If the project runs over budget or the contractor fails to complete work, the lender can draw from your down payment to cover losses.

Once construction is complete and you refinance into a permanent mortgage, your down payment is credited toward the new loan or returned to you, depending on the lender's terms. Read your construction loan agreement carefully to understand when and how you recover that money.

Down payment requirements when you already own the land

Owning the land outright changes the down payment calculation. Your land is collateral, which reduces the lender's risk. Some lenders will finance 80 to 90 percent of construction costs if you own the land free and clear, meaning you only need 10 to 20 percent down for the building phase.

If you have a mortgage on the land, the calculation is more complex. The lender will want to know the land's current value and what you still owe. If you have significant equity in the land, they may lower the construction down payment. If you owe most of the land's value, they'll treat it like any other construction project and require 20 to 25 percent down.

Some lenders allow you to refinance the land mortgage and the construction loan together into one package. This can reduce your total down payment requirement, but it also means you're borrowing against the land's value to fund construction. Discuss this option with your lender early, because it affects your overall financing structure.

Comparing down payment requirements across lender types

Lender TypeTypical Down Payment RangeNotes
Traditional bank20–25%Stricter requirements, longer approval, lower rates if you may have access to.
Credit union15–20%May offer better rates to members; approval can be faster.
Mortgage broker10–20%Can shop multiple lenders; may find options for weaker credit.
Portfolio lender10–20%Holds loans in-house; more flexible on credit and experience.
FHA construction loan3.5–10%Government-backed; requires FHA-approved lender and builder; longer timeline.

Portfolio lenders—banks that keep loans on their own books rather than selling them—often have more flexibility on down payments. They can approve borrowers with lower credit scores or less building experience because they're not selling the loan to investors with strict guidelines.

FHA construction loans exist but are less common. They allow down payments as low as 3.5 percent if you meet FHA requirements. However, the approval process is slower, and you must use an FHA-approved lender and builder. FHA loans also require mortgage insurance, which adds to your monthly payment.

How to reduce your down payment requirement

Improve your credit score before applying. A score above 740 opens doors to better rates and lower down payment requirements. Pay down existing debt to lower your debt-to-income ratio. Lenders want to see that you can handle the construction loan payment plus your other obligations.

Hire an experienced, licensed general contractor with a strong track record. Lenders view this as lower risk and may reduce your down payment by 5 to 10 percent. Get references and ask the lender if they've worked with this contractor before.

Put down more than the minimum if you can. A 25 percent down payment instead of 20 percent shows the lender you're serious and reduces their risk. Some lenders offer rate discounts for larger down payments.

Consider a construction-to-permanent loan, which locks in your permanent mortgage rate during construction. Some lenders offer slightly lower down payments on these combined products because they know they'll keep your business after construction ends.

Frequently Asked Questions

Can I use a gift for my construction loan down payment?

Most lenders accept gift funds for down payments, but they require a gift letter from the donor stating the money is a gift, not a loan. The donor usually cannot have any claim to the property. Some lenders limit how much of your down payment can come from gifts; verify this with your lender before accepting money from family.

What if I don't have 20 percent down for a construction loan?

You have several options: find a lender that accepts 10 to 15 percent down (credit unions and portfolio lenders often do), improve your credit and debt ratios to may have access to for lower down payments, use an FHA construction loan if you meet the requirements, or partner with a co-borrower who can contribute to the down payment.

Do I pay interest on the down payment during construction?

No. Your down payment sits in escrow and earns little to no interest. You pay interest only on the construction loan funds that are actually disbursed. Once you refinance into a permanent mortgage, you begin paying interest on the full loan amount, which includes the down payment you made.

Can I get my down payment back if the project is abandoned?

Rarely. If the project fails or is abandoned, the lender uses your down payment to cover their losses and any unpaid contractor bills. Read your loan agreement to understand what happens to your down payment if construction stops. Some lenders have clauses that protect a portion of your down payment in specific scenarios, but this is not standard.

Is the construction loan down payment the same as the permanent mortgage down payment?

Not necessarily. When you refinance into a permanent mortgage, that loan may have its own down payment requirement. However, most lenders credit your construction loan down payment toward the permanent mortgage down payment, so you don't pay twice. Confirm this in writing before you close on the construction loan.
