How to Document Gift Funds and Large Deposits on a Conventional Loan

The Quick Read: you document gift money with a signed gift letter from an acceptable donor, proof the donor had the funds or that the transfer happened, and your own bank statement showing the deposit. Large deposits that are not gifts need a paper trail of their own. The lender tests each single deposit against your income and asks you to source any unexplained portion. Funds nobody can verify do not count toward your down payment, closing costs, or reserves.

What Lenders Mean by a “Large Deposit”

A large deposit is a single deposit that exceeds 50% of your total monthly qualifying income. That is Fannie Mae’s test, laid out in its depository accounts rules. The trigger is tied to your income, not a fixed dollar amount. A $5,000 rule of thumb you may have heard is wrong.

Why do lenders care? They need to know the money is yours, that it did not come from an undisclosed loan, and that it will still be there at closing. Unverified funds cannot be used for the down payment, closing costs, or reserves. Reserves are the cash left in your accounts after closing.

Freddie Mac’s test is close but not identical. Under its large-deposit rule, the threshold also factors in an amount drawn from the asset calculation used in the debt-to-income ratio. It applies to deposits made no more than 60 calendar days before the application date, made on or before the note date, and reflected in the file. Fannie typically reviews about two months of statements. Both guides change, so your loan officer should check the current version against your file.

Most deposits never become an issue. The lender nets out anything identifiable on the statement, such as payroll direct deposits or a tax refund. The test runs only on the unsourced remainder.

Here is Fannie’s own example, restated in percentages. Someone with modest monthly income deposits an amount well above half of it. Most of that deposit is a documented tax refund. Only the small unsourced piece gets tested, and it lands at 12.5% of income. It is not a large deposit.

How Gift Funds Work on a Conventional Loan

Gifts are allowed on a principal residence or second home. Under Fannie Mae’s personal gifts rules, a gift can cover all or part of the down payment, closing costs, or reserves, subject to minimum borrower contribution requirements. Gifts are not allowed on an investment property.

Leverage still comes from the program. Across the conventional programs we place files with, a first-time buyer on a one-unit primary residence with a fixed rate can reach 97% loan-to-value (3% down), and other primary-residence purchases reach 95% (5% down). Second homes go to 90%. Those figures are subject to lender guidelines and full file review. A gift can fund part of that down payment, but the rest of the rules still apply.

The own-funds question is the one that surprises people. On Fannie loans at 80% loan-to-value or less, on a one- to four-unit primary residence or a second home, all the funds needed can come from a gift. Above 80%, a one-unit primary residence generally needs none of your own money. A two- to four-unit home or a second home needs at least 5% from your own funds. Confirm those figures on the live Fannie page, because the guide gets updated.

If a seller-side gift of equity is involved, it is a different animal, covered below.

Who Can Give, and Who Can’t

A donor has to be acceptable under the agency rules, and an interested party cannot be the donor. The builder, developer, real estate agent, or anyone with a stake in the sale is out.

Relatives are the classic donors. The agencies have widened the list over time. Freddie Mac’s Bulletin 2022-25 broadened “Related Person” to include unrelated people with close, family-like ties to the borrower. It also added estates and trusts of Related Persons. A later Freddie bulletin lets a business owned by a Related Person act as donor, with specific letter language. Secondary summaries say Fannie recently widened its non-relative category too, covering partners, fiancé(e)s, and mentor-type relationships. Ask your loan officer which version applies to your file.

Two edge cases come up often:

• Seller as donor. Not allowed. The seller has a stake in the sale, so the seller cannot be the donor. Seller credits for closing costs are a different thing from a gift.
• Donor living with you. A gift from an acceptable donor who has lived with you for the last 12 months can be treated as your own funds.

The widened rules are not unlimited. Plenty of generous people still do not qualify as donors.

Documenting a Gift, Step by Step

Think of the gift file as three pieces of paper that must agree with each other dollar for dollar.

1. The gift letter. The donor signs it. It states the dollar amount, says no repayment is expected, and lists the donor’s name, address, phone number, and relationship to you. Lenders often also want the transfer date. Details can vary by lender, so get the lender’s template before the donor writes anything.

2. Proof the money exists or moved. The lender must verify the funds are either in the donor’s account or already in yours. Evidence can be the donor’s check plus your deposit slip, an electronic transfer record, or a settlement statement showing the donor’s check arrived at closing.

3. Your own statement. If the gift has already landed, it shows up on your bank statement as a deposit. That deposit may trip the large-deposit test, and the gift letter plus transfer proof is how you clear it.

The CFPB tells buyers to ask the loan officer early whether gift funds are allowed with the chosen loan. Do that before the money moves.

Deposit Early or Wire at Closing?

Some lenders accept a wire straight to the closing agent, which can spare the donor from sharing bank statements. Others still want the donor’s account evidence. Confirm before anyone sends anything.

Documentation by Deposit Source

Gifts are only one source of big deposits. Here is how the common ones are handled.

Cash is the hard one. Cash with no traceable origin invites questions that are tough to answer. If you are saving toward a purchase, depositing money the normal way as you go beats a pile of cash deposited all at once.

Wedding gifts have their own handling. Freddie’s older guide excerpts ask for a copy of the marriage certificate and verification of the funds in your account. Treat that as a pointer, not a current rule, and have your loan officer confirm.

Writing a Letter of Explanation

When a deposit is flagged, the underwriter asks for a letter of explanation. Keep it short and factual. A simple skeleton:

• What the deposit was and its date.
• Where the money came from.
• Which documents are attached to prove it.
• Your signature and the date.

Do not guess. Attach the paper. A letter that says “birthday money from family” with nothing behind it does not clear a condition.

Already Deposited and No Paperwork?

It happens often. A parent sends the money before anyone mentions a gift letter. Fix it in this order:

1. Tell your loan officer right away.

2. Get the signed gift letter from the donor.

3. Collect the donor’s proof of funds or the transfer record.

4. Add your statement showing the deposit.

5. Write a letter of explanation if the underwriter asks.

Most of this can be repaired after the fact. The one thing that cannot be repaired is a donor who will not provide proof, or a source that does not exist.

What Happens If a Deposit Can’t Be Sourced

Under Freddie, if an unverified large deposit is not needed to qualify, the lender reduces the funds used for qualification by the unverified amount. If you need that money to close or hold reserves, the file can fall short. That can shrink your cash to close and, in a tight file, sink the approval.

Options at that point are limited but real. A larger documented contribution from another source can fill the gap. A different donor can step in. In some cases the loan structure changes. A larger documented down payment can also lower the loan amount.

Gift of Equity: A Different Tool

A gift of equity is a gift from the seller to the buyer, built from part of the seller’s equity. It shows up as a credit in the transaction. Fannie’s gift of equity rules allow it on principal residence and second home purchases. The file needs a signed gift letter and the settlement statement listing the credit.

Two limits matter. A gift of equity cannot be used for reserves. And because it works as a price credit, the contract price, appraised value, and loan-to-value drive the minimum-contribution test. Ask your lender how an appraisal treats the gift on your particular file.

Where the General Rule Breaks

• Investment property. Gifts are not allowed. Occupancy decides the rules, so a rental purchase follows different ones.
• Foreign accounts. Freddie says the large-deposit rules apply when documents from non-U.S. accounts show a large deposit.
• Refinances. Secondary sources say large-deposit sourcing applies on purchases when funds are needed to close, not on refinances. Treat that cautiously and confirm with your loan officer.
• Repaying a gift. The gift letter says no repayment is expected. Paying the money back later contradicts the letter and could be a misrepresentation to the lender.
• Gift letter alone. It is not enough. The lender must also verify the funds.

Credit and ratios still run alongside all of this. Across the wholesale conventional programs we place with, the starting decision score is 620, and the automated finding governs most files, with a total ratio ceiling of 50%. A clean gift does not fix a weak credit profile.

Timing Your Transfers

Fannie reviews roughly two months of statements and Freddie looks back up to 60 days before application. So the timing of a transfer changes how many questions you get. Money that moved before those windows often draws fewer. Money that moves mid-process draws more.

A practical timeline:

• Before you apply. Ask your loan officer which donors and documents the loan needs. Decide whether the gift will be deposited or wired at closing.
• While the file is in process. Do not move money around casually. Keep every statement page, including blank ones.
• After underwriting asks. Answer each condition with the document it names, nothing extra and nothing missing.

Questions to Ask Your Loan Officer

• Is my donor acceptable under this loan’s rules?
• Do I need any of my own funds at my leverage and occupancy?
• Does the donor need to share bank statements, or can funds go to the closing agent?
• Which deposits on my statements will be flagged?
• Can the gift cover reserves, or only the down payment and closing costs?

Key Terms Defined

Large deposit: a single deposit above 50% of your monthly qualifying income, measured on the part you cannot source.

Gift letter: a signed donor statement giving the amount and confirming no repayment is expected.

Gift of equity: a seller’s gift of part of the home’s equity, applied as a credit in the sale.

Reserves: cash left in your accounts after closing.

Interested party: anyone with a stake in the sale, such as a builder or real estate agent.

Sourcing: proving where a deposit came from.

Gift tax questions belong to the donor and their tax adviser.
