Most construction loans require a down payment, but the amount varies by lender and loan type
Yes, construction loans typically require a down payment. The amount ranges from 10% to 25% of the total project cost, depending on your lender, the type of construction loan, and whether you are building a new home or renovating an existing one. Some lenders require more if you have a lower credit score or limited construction experience.
The down payment for a construction loan works differently than a mortgage down payment. You pay it upfront to the lender before construction begins, and it counts toward your total equity in the project. The lender then disburses the remaining funds in stages as construction progresses, rather than giving you one lump sum at closing.
A few specialty programs or lenders may accept lower down payments—sometimes as low as 5%—but these typically come with higher interest rates or additional fees. If you cannot meet the down payment requirement, you have options: finding a co-borrower, using a construction-to-permanent loan (which may have different terms), or waiting until you have saved more.
Key Takeaways
- Construction loans usually require 10% to 25% down, paid to the lender before work begins, not to the contractor.
- The down payment is held as your equity and does not go toward construction costs directly—the lender disburses funds in stages as work is completed.
- Your credit score, debt-to-income ratio, and the lender's assessment of the project's feasibility all affect the down payment amount you will be asked to pay.
- Construction-to-permanent loans sometimes have lower down payment requirements than standalone construction loans, but rates and terms vary by lender.
- If you cannot meet the down payment, you can explore co-borrower options, delay the project, or look for lenders that specialize in lower-down-payment construction financing.
How construction loan down payments differ from mortgage down payments
A construction loan down payment is not the same as a down payment on a finished home. With a mortgage, you put down a percentage of the home's purchase price and the lender gives you the rest as a single check at closing. With a construction loan, you put down a percentage of the estimated total project cost, and the lender holds that money as your equity stake in the project.
The lender then releases funds in draws or disbursements as construction milestones are met. A typical schedule might release funds when the foundation is complete, when framing is done, when the roof is on, and so on. An inspector or the lender's representative visits the site to verify work before each draw is released. Your down payment stays with the lender as your ownership share and is credited toward your final mortgage when construction ends.
This structure protects the lender because they are not handing over all the money at once to a contractor they do not know. It also protects you because the lender has incentive to make sure the work is actually being done before releasing the next payment.
Down payment amounts by lender type and loan structure
The down payment you need depends on which lender you work with and what kind of construction loan you choose. Bank construction loans typically require 15% to 25% down and have stricter requirements around credit score, income verification, and project plans. Credit union construction loans often have similar requirements but may offer slightly lower rates. Mortgage lenders that offer construction financing may require 20% to 25% down.
Construction-to-permanent loans (also called one-time-close loans) sometimes allow lower down payments—as low as 10%—because the lender is financing both the construction and the permanent mortgage. This reduces their risk since they know you will have a traditional mortgage in place when construction is done. The tradeoff is that rates on construction-to-permanent loans are often slightly higher than on a standalone construction loan.
Portfolio lenders and private lenders may accept 5% to 10% down, but interest rates are usually 1% to 3% higher than bank rates, and fees are more common. These lenders are less regulated and hold loans in their own portfolio rather than selling them on the secondary market, so they have more flexibility on down payment but charge for that flexibility.
| Lender Type | Typical Down Payment | Credit Score Requirement | Timeline to Approval |
|---|---|---|---|
| Bank or mortgage lender | 15–25% | 680+ | 4–8 weeks |
| Credit union | 15–25% | 680+ | 4–8 weeks |
| Construction-to-permanent | 10–20% | 680+ | 4–8 weeks |
| Portfolio or private lender | 5–15% | 620+ | 2–4 weeks |
What factors determine your down payment amount
Lenders do not use a single formula for down payments on construction loans. They look at your credit score, your debt-to-income ratio, the size and complexity of the project, whether you are an experienced builder or a first-time homeowner, and the quality of your project plans and contractor.
If your credit score is below 700, expect to put down 20% or more. If you have a high debt-to-income ratio—meaning your existing monthly debt payments are already large relative to your income—the lender may ask for a larger down payment to reduce their risk. If your project is unusual (a custom home on difficult terrain, for example), or if your contractor is new or unproven, the lender may also ask for more money down.
Conversely, if you have a strong credit score (740+), low debt-to-income ratio, detailed plans from a licensed architect, and a contractor with a solid track record and references, you may be offered a down payment at the lower end of the range—sometimes as low as 10% even with a traditional bank.
Where the down payment money comes from and where it goes
Your down payment comes from your own savings or assets. You cannot borrow it from another lender or use a gift that comes with strings attached (most lenders require gift money to be documented and truly given, not loaned). Some lenders allow a portion of the down payment to come from a gift, but you will need a signed gift letter stating the money is a gift and not a loan you have to repay.
The down payment is wired or transferred directly to the lender's escrow account, not to the contractor. The lender holds it there and credits it against your equity in the project. When construction is complete and you close on the permanent mortgage, the down payment is applied to your loan balance or returned to you as part of the closing process, depending on your loan structure.
You do not pay the contractor directly from your down payment. The contractor is paid from the construction loan draws. This is why the lender requires detailed invoices and site inspections—they are verifying that the work is actually done before they release money to pay the contractor.
Options if you cannot meet the down payment requirement
If the down payment is out of reach, you have several paths forward. The first is to delay the project and save more money. Construction costs do not always rise quickly, and waiting six months to a year to save an additional 5% or 10% may be worth it to avoid higher interest rates or private lending fees.
The second option is to find a co-borrower—a spouse, family member, or business partner—who can contribute to the down payment and be listed on the loan. The co-borrower's income and credit are factored into the approval, which may help you may have access to for a lower down payment or better rate.
The third option is to explore construction-to-permanent loans, which sometimes have lower down payment requirements than standalone construction loans. You will want to compare rates and fees across multiple lenders because the savings on down payment can be offset by higher interest rates.
The fourth option is to work with a portfolio lender or private lender that accepts lower down payments. Be aware that these lenders typically charge higher interest rates (often 2% to 4% above bank rates) and may charge origination fees, appraisal fees, or other costs that a bank would not. Calculate the total cost over the life of the loan before committing.
How down payments affect your interest rate and total loan cost
A larger down payment typically results in a lower interest rate. When you put down 20% or 25%, lenders see you as lower risk because you have more of your own money at stake. A 15% down payment might cost you 0.25% to 0.5% more in interest. A 10% down payment might cost you 0.5% to 1% more. A 5% down payment can cost 1% to 2% more.
On a $400,000 construction project, the difference between a 10% and 20% down payment is $40,000 upfront. But if that extra $40,000 down payment saves you 0.5% in interest over a 20-year loan, you will save roughly $40,000 to $50,000 in interest charges. The math often favors a larger down payment if you have the cash available and are not depleting your emergency savings to do it.
Some lenders also charge mortgage insurance or lender's insurance on construction loans with down payments below a certain threshold (often 20%). This insurance protects the lender if you default, and the cost is added to your monthly payment or rolled into the loan balance. If you can avoid this by putting down 20% or more, it is usually worth doing.
Frequently Asked Questions
Can I use a gift for my construction loan down payment?
Yes, but the lender will require a signed gift letter from the person giving you the money, stating that it is a gift and not a loan you have to repay. The gift giver may also need to provide bank statements showing they have the funds. Some lenders allow the entire down payment to be a gift; others require you to contribute at least 5% of your own money.
What happens to my down payment after construction is done?
Your down payment is credited toward your equity in the project. When you close on the permanent mortgage, it is applied to your loan balance. You do not get it back as cash; instead, it reduces the amount you have to borrow for the permanent mortgage.
Do I have to pay the down payment all at once, or can I pay it in installments?
Most lenders require the full down payment to be paid before construction begins. Some construction-to-permanent lenders may allow a portion to be paid at the construction closing and the remainder at the permanent closing, but this is less common. Ask your lender about their specific requirements.
What if my project costs more than the estimate and I need extra money?
If construction costs exceed the original estimate, you have a few options: pay the overage out of pocket, ask the lender for a loan modification to increase the construction loan amount (which may require a larger down payment on the increase), or negotiate with the contractor to reduce scope. Most lenders will not automatically increase the loan amount without your request and approval.
Can I get a construction loan with no money down?
No. All construction lenders require a down payment because they need you to have financial skin in the game. If a lender claims to offer zero-down construction financing, they are either not a legitimate lender or the terms are so unfavorable (extremely high rates, large fees, or both) that the offer is not worth considering.
