Financing a Custom Home When Your Builder Requires a Large Deposit
Editorial review: My Construction Path team ·
If your custom home builder requires a large deposit before your construction loan closes, talk to your lender before you pay. Some lenders can credit a documented builder deposit toward your side of the deal or reimburse certain costs at closing; others can't. Put the deposit in the contract and protect it where possible.

Why do custom home builders ask for a deposit before the loan closes?
Builders often need money up front for design, engineering, permits and ordering materials. A deposit also shows the builder you're committed before it reserves crews and a spot on its schedule.
That's common on custom homes. The challenge is timing: the deposit is often due weeks or months before your construction loan closes, and once the money leaves your account, it's at risk if the project stalls.
Can I pay a builder deposit before my construction loan closes?
Often, yes, but tell your lender first. Lenders want to see where every dollar in the deal came from and where it went.
A deposit paid before closing can affect:
- The cash you still need to bring. Money you've already paid isn't in your account at closing, so the lender will want proof it went to the builder.
- The budget and contract. The lender compares your contract, cost breakdown and deposit to make sure the numbers match.
- The lender's review. Some lenders won't close if work started before the loan, so a deposit for materials is different from a deposit that lets crews break ground. Our guide to starting construction before your loan closes explains why.
Will the lender count my deposit or pay it back at closing?
It depends on the lender and program. Some credit a documented deposit toward your side of the deal; some reimburse certain early costs at closing; some do neither.
Ask each lender these questions before you pay:
| Question to ask the lender | Why it matters |
|---|---|
| Do you credit a builder deposit toward my contribution? | It may reduce the cash you need at closing. |
| Can any of it be reimbursed at closing? | Some lenders repay certain documented costs, such as plans or permits. |
| What proof do you need? | Usually the contract, a receipt and bank statements showing the funds left your account. |
| Does it matter what the deposit pays for? | Design and permit costs may be treated differently from materials or site work. |
| Do you need to approve the builder first? | Paying a builder the lender later won't approve can leave you stuck. |
Builder approval is often the step to finish first. See our guide to construction loan builder approval. If a builder relationship falls apart later, see changing builders after closing.
How can I protect a large builder deposit?
Use the contract, an escrow arrangement and paperwork to limit the risk. The goal is to tie your money to clear terms and to work that's actually done.
- Write it into the contract. State the deposit amount, what it covers, when it's due, and when it's refundable.
- Use escrow or a separate account. A third-party escrow, or a builder's dedicated project account, keeps your money apart from the builder's other jobs. Ask an attorney what's available in your state.
- Pay the builder, not individuals. Pay by check or bank transfer to the company named in the contract.
- Get receipts and lien waivers. Ask for a lien waiver from the builder and major suppliers when your deposit pays for materials.
- Check state rules. Some states limit how large a deposit a contractor can require. Maine law, for example, caps it on home construction contracts unless both sides agree in writing to waive the limit.
The Maine Attorney General's office explains why lien waivers matter:
"To avoid a mechanic's lien on your property, you should ask for a lien waiver when you make a payment to contractors or subcontractors. A lien waiver is evidence that the person who gave the waiver received payment in the amount indicated."
What happens to the money after the loan closes?
After closing, the lender usually controls how construction money reaches the builder, through a draw schedule tied to inspections.
Fannie Mae's Selling Guide section on single-closing construction-to-permanent loans puts it this way: "When a single-closing transaction is used, the lender will be responsible for managing the disbursement of the loan proceeds to the builder, contractor, or other authorized suppliers." That's one reason a large deposit outside the loan carries more risk than money paid through draws. Our guide to how construction loan draws work covers inspections and lien waivers during the build.
Why does the deposit stay at risk for so long on a custom home?
Because custom builds take time. A deposit paid before closing may sit with the builder for months before the home is finished.
The U.S. Census Bureau tracks custom homes built on the owner's land as "contractor-built" houses (Census definitions). As of the Census Bureau's 2025 annual data, published July 1, 2026, those homes took an average of 10.5 months from start to completion, compared with 6.1 months for homes built for sale (Census start-to-completion times). That excludes the time before construction starts, when many deposits are paid.
What should I do before I sign and pay?
Work through these steps in order:
- Check the builder. Confirm licensing where your state requires it, insurance, references and recent custom homes.
- Talk to lenders. Ask how each one treats a deposit paid before closing.
- Get builder approval. Start the lender's builder review before money changes hands.
- Negotiate the deposit. Ask whether part can wait until closing or be tied to milestones such as finished plans or issued permits.
- Put it in writing. Contract terms, refund conditions, escrow details and a receipt.
- Keep a paper trail. Save bank statements showing the transfer and any lien waivers.
Frequently asked questions
Can I pay my builder a deposit before my construction loan closes?
Often, yes, but tell your lender first. The lender needs to know what you paid, why, and how it shows up in the contract and budget.
Will I get my deposit back at closing?
Sometimes. Some lenders credit a documented deposit toward your side of the deal or reimburse certain costs at closing, and some don't. Ask before you pay.
Can the deposit go into escrow?
Often it can. A third-party escrow or a builder's separate project account adds protection. Ask your builder and attorney what's available in your state.
What is a lien waiver?
A signed statement that a contractor or supplier has been paid for the amount shown. It helps protect you from a mechanic's lien if the builder doesn't pay its subs.
What if my builder won't start without a large deposit?
Ask what the deposit covers, whether part of it can wait until closing, and whether your lender can fund early costs such as plans or permits through the loan.
