Someone in your family has offered to help you buy a house. That's the good part.
Here's the part that doesn't get explained until it's already gone wrong: the money isn't usually the problem. The paper trail is. A gift that moves the wrong way, at the wrong time, without the right documents behind it can stop counting as your money — and a lender has to subtract it from what you've got to close with.
These problems come from sequence, not from the money itself, and the sequence is something you can control. Here's the order.
This section describes lender documentation requirements. It's general information, not legal advice.
Every loan program requires a written statement from the person giving you the money saying that no repayment is expected. Not "pay me back when you can." Not a handshake.
This isn't a formality. If money is actually being loaned to you, two things happen. Under Fannie Mae's rules, personal unsecured loans can't fund a down payment, closing costs, or reserves — so it stops being an eligible source. And it's a debt, which belongs on your application and changes your debt-to-income ratio.
One version of family borrowing can work: a loan secured by an asset you already own. Talk to your loan officer before you and your relative agree on anything.
Be direct with yourself about which one you have. Signing a letter that says "no repayment expected" when repayment is expected is a false statement on a mortgage application. Don't put your family member in that position either.
It's easy to assume there's one rule. There are several, and they don't line up.
Conventional (Fannie Mae). A relative — spouse, child, or anyone related by blood, marriage, adoption, or legal guardianship. The rules also reach a domestic partner (and their relatives), someone you're engaged to marry, a former relative, or a person with a long-standing familial-like or mentorship relationship with you. Freddie Mac, the other conventional investor, keeps its own list — close but not identical, so ask which one your loan is headed to.
FHA. Narrower in one direction, wider in another. FHA works off a defined family list — child, parent or grandparent (including step- and foster-), spouse or domestic partner, sibling or step-sibling, aunt, uncle, and in-laws. Notice what isn't on it: cousins, nieces, nephews, and fiancés. Those work on a conventional loan.
But FHA also accepts gifts conventional guidelines don't treat as gifts at all: your employer, your labor union, a close friend with a clearly defined and documented interest in you, a charitable organization, or a government agency running a homeownership program.
VA and USDA. Neither imposes a relationship test. There is no family list.
So "can my aunt help me?" has a different answer depending on which loan you're using — worth asking before you pick the loan, not after.
Every program blocks money from the builder, the developer, the real estate agent, or anyone else with an interest in the transaction — or anyone affiliated with them. On FHA the prohibition is statutory and reaches anyone who financially benefits from the transaction, or anyone those parties reimburse, directly or indirectly.
Now the part that surprises people, and it cuts in your favor:
On a conventional loan, the seller can be the donor if the seller independently qualifies and isn't affiliated with any other interested party. A parent selling a house to their own child is the standard example.
On FHA, a seller can't hand you cash toward your required investment — but a seller who is a Family Member can give you a gift of equity, meaning they sell below market and the difference becomes a credit in the transaction. Only Family Members can do that on FHA; an employer or close friend can gift cash and cannot give equity.
So "the seller can never gift you anything" is an overstatement on both programs. If you're buying from a relative, ask.
Short document, specific contents. Fannie Mae requires the dollar amount — and expressly allows a maximum rather than an exact figure, which helps when you don't yet know your final cash to close. It needs the donor's statement that no repayment is expected, plus their name, address, phone number, and relationship to you.
FHA differs: the letter is signed and dated by both the donor and you, and FHA doesn't carry Fannie's explicit permission to state a maximum, so expect your lender to want a firm number.
One that catches people: if the donor lives with you and their gift is being pooled with your own funds, Fannie Mae also wants a certification that they've lived with you for the past twelve months and will continue to in the new home. Nobody expects that one.
The gift letter proves intent. Something else has to prove the transfer, and the programs disagree about what's enough.
Conventional gives you options. The lender verifies the funds are either sitting in the donor's account or already moved to yours. The donor's check plus your deposit slip, a withdrawal slip plus your deposit slip, an electronic transfer to you or to the closing agent, the donor's check made out to the closing agent, or a settlement statement showing receipt — any of those work. Fannie Mae doesn't require tracing where the donor got the money, though individual lenders sometimes ask.
FHA is stricter and wants both sides paired. Before settlement: the donor's bank statement showing the withdrawal and evidence of the deposit into your account. At settlement, FHA's list is closed — electronic transfer from the donor's account, a bank certified check, a cashier's check, or another official bank check. A Closing Disclosure line item showing gift funds received isn't on that list, which is why lenders won't take it alone on an FHA file.
VA and USDA are more flexible, and both will accept a Closing Disclosure showing receipt as one option.
Two things cause trouble regardless of program: cash handed to you in person, and money that moves through a third account on the way. Every hop has to be documented.
This is the most useful paragraph here.
Lenders have to source large deposits, and the trigger isn't the same everywhere — Fannie Mae's is a deposit that's large relative to your monthly qualifying income, while USDA uses a flat dollar threshold on any non-payroll deposit. Assume anything that isn't your paycheck gets asked about.
If a big deposit lands and nobody can document where it came from, the lender doesn't get to shrug. Fannie Mae's rule is that verified funds are reduced by the amount of the undocumented deposit, and then the lender checks whether you still have enough to close. A gift documented the way the program requires is already sourced, which avoids that. Underwriting can still ask for more.
So: gift letter first, transfer second, statements saved the day it happens — not reconstructed three weeks later from memory.
And on documents generally: don't email tax returns, bank statements, or your donor's bank statements. They carry Social Security numbers and full account numbers. Ask your loan officer for a secure upload link and use it, for your documents and your donor's.
One more distinction worth knowing: a gift comes from a person with no repayment. A grant comes from an institution with no repayment. A down payment assistance second is neither — it's a real lien recorded against your home, with its own terms. If someone offers to "help with your down payment," ask which of the three it is.
This section is general information, not tax advice. Loan officers aren't accountants — ask a CPA about your own situation.
People ask whether a large gift creates a tax problem. That's a question for the donor's accountant, governed by IRS gift-tax rules that are entirely separate from whether the money can be used on a mortgage. Loan program rules don't cap the size of a gift. Whether your relative has a filing obligation is their CPA's call — send them before they write the check, not after.
If someone is helping you buy, in this order:
If you're not sure whether the person helping you qualifies as a donor on the loan you're using — or which loan type makes the most sense given who's helping — that's worth asking now rather than during underwriting.
Reaching out is free and there's no obligation. A general question is not a loan application, and nothing here is an approval, a pre-approval, or a commitment to lend. Please don't send documents until we've asked for them and sent you a secure upload link.
