Borrowing for a down payment is legal, but most lenders will not allow it

You can legally borrow money from anyone and use it for a down payment. There is no law against it. What matters is whether your lender will accept it — and most will not. When you apply for a mortgage, the lender will ask where your down payment money came from. If you say you borrowed it, they will typically deny your loan or demand you use your own cash instead.

The reason lenders care is skin in the game. They want to know you have your own money at risk. If you borrowed everything, including the down payment, you have borrowed 100% of the home's value. That makes you a much riskier borrower — if the market drops or you lose your job, you have no equity cushion and nothing stopping you from walking away. Lenders see this as a sign you may default.

This rule applies whether you borrowed from a bank, a family member, a credit card, or a personal loan. The source does not matter. What matters is that the lender sees the money as a gift or as your own savings, not as debt you owe to someone else.

Key Takeaways

  • Borrowing money for a down payment is not illegal, but mortgage lenders will reject your application if they discover the down payment is a loan rather than your own funds.
  • Lenders verify the source of down payment money by asking for bank statements and sometimes requiring a written statement from the person or institution that gave you the money.
  • A gift from a family member is treated differently than a loan — the lender will ask the gift-giver to sign a letter stating the money does not need to be repaid.
  • Some lenders allow a co-signer to borrow money for their own down payment contribution, but the co-signer's debt still counts against their credit and income when the lender evaluates the mortgage.
  • If you lie about the source of your down payment, you commit mortgage fraud, which is a federal crime that can result in fines up to $1 million and prison time up to 30 years.

How lenders verify where your down payment came from

When you submit a mortgage application, the lender will ask for bank statements covering the last two to three months. They are looking for a pattern: do you have a history of saving this money, or did a large deposit suddenly appear? A sudden large deposit raises a red flag.

If the lender sees a deposit they do not recognize, they will ask you to explain it. You will need to provide documentation — a letter from the person or institution that gave you the money, a loan agreement, or a bank statement showing the transfer. At that point, the lender will decide whether to accept the source or deny the loan.

Some lenders are stricter than others. A bank offering a conventional mortgage (not backed by the federal government) may have more flexibility. A lender offering an FHA loan (backed by the Federal Housing Administration) has stricter rules about down payment sources and will almost always reject borrowed money.

The difference between a gift and a loan

If a family member gives you money for a down payment as a gift — meaning you do not have to pay it back — the lender will treat it as your own funds. The gift-giver will need to sign a gift letter stating that the money is a gift, not a loan, and that they do not expect repayment. The lender will keep this letter in your file.

A gift letter is a simple document. It names the amount, states that it is a gift, and is signed by the person giving the money. Some lenders have a template you can use. The key phrase is that the money "does not need to be repaid."

If you borrow money from a family member instead, you have a debt. Even if you have a handshake agreement and no written contract, the lender may ask whether you owe money to anyone else. If you lie and say the money is a gift when it is actually a loan, you are committing fraud.

What happens if you lie about the source of your down payment

Lying to a lender about where your down payment came from is mortgage fraud. It is a federal crime. The penalty can include fines up to $1 million and prison time up to 30 years, depending on the amount and the circumstances.

Lenders have tools to catch this. They review bank statements, they contact gift-givers to verify their statements, and they cross-check your credit report against the debts you reported. If they find a discrepancy — for example, a new personal loan you did not mention — they can deny your application or, if they have already closed the loan, report you to federal authorities.

Even if you get away with it initially, the fraud can surface later. If you refinance, sell the home, or apply for another loan, the lender may discover the original lie. At that point, you could face criminal charges years after the original transaction.

Alternatives if you do not have enough cash for a down payment

If you cannot save enough for a down payment and cannot borrow it, you have other options. Some loan programs allow down payments as low as 3% or even 0%. An FHA loan typically requires 3.5% down. A VA loan (for military members and veterans) requires 0% down. A USDA loan (for rural properties) also requires 0% down.

These programs exist because lenders understand that many buyers cannot save a large down payment. The trade-off is that you will pay mortgage insurance — an extra monthly fee that protects the lender if you default. Over time, this insurance costs more than a larger down payment would have, but it lets you buy sooner.

Another option is to wait and save. If you can delay buying for six months or a year, you may be able to save enough to put down 5% or 10% without borrowing. This reduces your mortgage insurance costs and gives you more time to improve your credit score, which can lower your interest rate.

What a co-signer can and cannot do

If you have a co-signer on your mortgage — someone who agrees to pay if you do not — that person can contribute their own money toward the down payment. Their contribution is treated the same way as yours: the lender will verify it came from their own savings or a gift to them.

However, if the co-signer borrows money for their contribution, the lender will see that debt on the co-signer's credit report. It will count against their debt-to-income ratio, which may reduce the total loan amount the lender will approve. In some cases, it may disqualify the co-signer entirely.

A co-signer is not the same as a gift-giver. A co-signer is legally responsible for the entire mortgage if you stop paying. A gift-giver has no obligation. If you are considering asking someone to co-sign, make sure they understand the risk they are taking on.

State and local rules about down payments

Most down payment rules come from the lender, not from state or local law. However, some states have programs that help first-time buyers with down payments. These programs may have their own rules about where the money can come from.

For example, some state housing finance agencies offer down payment assistance programs that give money directly to buyers. These programs typically do not allow you to borrow the assistance money — it is a one-time grant. If you receive assistance from one of these programs, you cannot use it to pay off a personal loan you took out for a down payment.

Check with your state's housing finance agency or your local housing authority to learn what programs are available in your area and what their rules are.

Frequently Asked Questions

Can I borrow money from my 401(k) for a down payment?

Yes, and this is one of the few types of borrowing lenders generally accept. A 401(k) loan is not considered a debt by most mortgage lenders because you are borrowing from yourself, not from an outside creditor. However, the lender will still see the loan on your credit report and may ask about it. Some lenders require you to pay off the 401(k) loan before closing on the mortgage.

What if I get a personal loan and tell the lender it is for something else?

That is fraud. The personal loan will show up on your credit report with the lender's name and the loan amount. When you apply for a mortgage, the mortgage lender will see it. If you claim you do not have any other debts, you are lying. This can result in denial or, if discovered later, criminal charges.

Can my employer give me money for a down payment?

Yes, if it is a gift. Your employer can give you money as a bonus or assistance, and you can use it for a down payment. The lender will ask your employer to sign a gift letter confirming it does not need to be repaid. If your employer expects you to repay it, it is a loan and the lender will likely reject it.

Will the lender know if I borrowed money from a friend?

Not automatically, but the lender will see large deposits in your bank statements. If you cannot explain where the money came from, the lender will ask. If you lie, you are committing fraud. If you tell the truth and say it is a loan, the lender will likely deny your application.

What if I pay back the loan before closing on the mortgage?

If you borrow money, use it for a down payment, and then pay back the loan before the mortgage closes, the lender may still find out. They will see the loan on your credit report and the large deposit in your bank statements. They may ask you to explain the timing. If you are honest and can show proof that the loan is paid off, some lenders may accept it — but this varies by lender and loan type.
