Family money for a down payment, the clean way

Family money makes a lot of first homes possible. It also raises questions your mortgage lender will absolutely ask. Here is how gifts and loans differ, what the paperwork looks like, and the three paths that keep everything clean.

Why the source of your down payment matters

Mortgage underwriters check where every dollar of your down payment comes from. In the industry this is called sourcing your funds. Large deposits in your bank account get flagged, and you will be asked to explain each one with a paper trail: statements, transfer records, sometimes a letter.

The reason is simple. The lender is deciding whether you can afford the house. If part of your down payment is secretly borrowed, you carry a debt they never counted, and the whole approval was based on wrong numbers. So underwriting draws a hard line between money that was given to you and money that was lent to you.

Gift or loan: the lender's definition, not yours

Inside a family, the line can feel blurry. "Pay us back whenever you can" feels like a gift with a handshake attached. A mortgage lender does not see it that way. To an underwriter there are exactly two categories:

• A gift is money you never have to repay. Most loan programs accept gift funds from close family, but they require a signed gift letter stating that repayment is not expected.
• A loan is money you do have to repay. It is a debt. It generally must be disclosed on your application, and the payment typically counts in your debt-to-income ratio.

Which category your family's money falls into is not a paperwork choice. It is a fact about your actual intentions. If both of you expect repayment, it is a loan, no matter what anyone writes down.

Three clean ways to use family money

After years around real estate closings, these are the three paths that consistently hold up. Each one is honest, and each one keeps the deal, the family, and the paperwork aligned.

1. A true gift, with a gift letter

This is the most common path. A parent or relative gives money outright, with no expectation of repayment. The lender provides a gift letter form. The giver signs it, and the letter states plainly that the money is a gift and repayment is not expected. Lenders often also want to see where the funds came from, so the giver may share a bank statement showing the withdrawal, and you show the matching deposit.

Gifts can raise a tax question for the giver, not for you. A giver who exceeds the annual gift tax exclusion generally files a gift tax return, though tax is rarely owed because of the large lifetime exemption. The IRS covers the basics at https://www.irs.gov/businesses/small-businesses-self-employed/frequently-asked-questions-on-gift-taxes. Many families run larger gifts past a tax professional first.

The key is that a true gift is truly a gift. If everyone quietly expects repayment, this is not your path. The next one is.

2. A disclosed family loan

Some mortgage programs allow part of the down payment to be borrowed, often with conditions, such as the loan being secured by an asset. The rules differ by program, so the only reliable answer comes from your loan officer. What is consistent everywhere: the family loan gets disclosed, and its monthly payment gets counted in your debt ratios.

Yes, that makes qualifying a bit harder. It is also the version where nobody has to hide anything, and where the deal survives an audit, a divorce, or a bad memory. A slightly smaller pre-approval that is real beats a bigger one built on a false gift letter.

A disclosed family loan needs real terms: a written agreement, an interest rate, a payment schedule. There is an IRS layer here too. The IRS generally expects loans between individuals to carry at least a minimum interest rate, published monthly as the Applicable Federal Rate at https://www.irs.gov/applicable-federal-rates. Loans below that rate can trigger imputed interest rules. A common approach is to set the rate at or slightly above the AFR, which is usually still far cheaper than any bank. Our guide to IRS rules for family loans walks through the details.

3. A family loan after closing, for everything else

Buying a house costs more than the down payment. Moving trucks, a fridge, blinds, the repair the inspection flagged, the first surprise from the water heater. A third path many families use: the buyer covers the down payment from savings or a documented gift, closes the mortgage, and then the family helps with a separate loan for the after-closing costs.

Timing is the whole trick here. Lenders re-verify credit and bank activity shortly before closing, so a new debt or a mystery deposit mid-process can stall or sink the deal. This path works precisely because the family loan happens after the keys are in your hand and the mortgage is fully done. Nothing hidden, nothing to explain, and the family money still lands where it helps.

Why written terms protect the family, not just the deal

Whichever path fits, the same rule applies: write it down. Memory drifts. "We said five years" becomes "we said whenever" by the third Thanksgiving. And if the person who lent the money passes away, an undocumented loan becomes a genuinely painful puzzle for the estate and the siblings.

There is a tax reason too. If a family loan is ever questioned, the IRS looks at whether it behaved like a real loan: a written note, a stated interest rate, an actual repayment history. Handshake loans with no records tend to get treated as gifts, with gift tax consequences for the lender. Our guide on loan versus gift digs into why that distinction matters so much.

This is exactly what Kinlend is built for. Kinlend is a documentation and tracking tool, not a lender, and no money ever moves through it. You and your family member set the terms together, both of you e-sign the loan agreement, and the payment schedule lives where you both can see it. Every payment gets confirmed by both sides, and gentle reminders go out so nobody has to nag anybody. It works on the web and on iPhone. Plans from $0.99 a month unlock e-signing and tracking.

Talk to the loan officer before the money moves

The cheapest fix in real estate is the conversation that happens early. Bring the family money up at pre-approval, not the week before closing. A good loan officer has seen every version of this and can tell you exactly what their program allows and what paperwork it needs.

Questions worth asking:

• Does this program accept gift funds from this relative, and what does your gift letter require?
• What paper trail do you need for the transfer?
• Would a disclosed family loan work with my numbers, and how would it change my approval?
• How long before closing does the money need to be in my account?

Every program is a little different, and conventional, FHA, and VA loans each have their own gift and borrowing rules. The loan officer's answer beats anything you read online, including this page.

Common questions

Can you borrow from family for a down payment?

Sometimes. Some mortgage programs allow borrowed down payment funds under specific conditions, but the family loan must be disclosed and its payment usually counts in your debt-to-income ratio. Your loan officer can confirm what a specific program allows before any money moves.

What is a gift letter?

A short signed statement, usually on the lender's own form, saying the money is a true gift and repayment is not expected. Most programs require one for gift funds, and many lenders also want a paper trail showing where the money came from and when it arrived.

Can we call it a gift and quietly repay it later?

No. Signing a gift letter for money you intend to repay is misrepresentation on a mortgage application, which is fraud. If repayment is the plan, the clean options are a disclosed family loan or family help arranged after closing.

Does a family loan need to charge interest?

The IRS generally expects loans between individuals to carry at least the Applicable Federal Rate, published monthly at https://www.irs.gov/applicable-federal-rates. Below that, imputed interest rules can apply. Many families set the rate at or just above the AFR, which is usually still far below bank rates.

Family money can be the difference between renting another year and getting the keys. Handled in the open, with the lender informed and the terms in writing, it stays what it was meant to be: help, not a headache.
