What it means
Underwriters care about two things when a large sum lands in a buyer's account: where it came from and whether it creates a debt. A gift letter answers both, and it is usually backed up with bank statements showing the money leaving the giver's account and arriving in the buyer's.
The reason repayment matters so much is the debt to income ratio, which compares a borrower's monthly commitments with their gross monthly income. A repayable family loan pushes that ratio up and can move a borrower from comfortably approved to declined.
A typical letter is short. It gives the giver's name, address and relationship to the buyer, the exact amount, the property address, a statement that the funds are a gift with no expectation of repayment, and signatures from both sides.
Lenders differ on who is allowed to give. Close family is almost always acceptable, more distant relatives and friends sometimes are, and gifts from anyone with an interest in the sale, such as the seller or the estate agent, are usually refused outright because they can distort the price.
The letter is a document of record, not decoration. Signing one that describes a loan as a gift is mortgage fraud, and side agreements to repay quietly later are exactly what the letter exists to rule out.
In practice
Real-world examples.
Example
First time buyers receive $40,000 from one set of parents towards a $50,000 deposit. The lender requires a gift letter from each parent, plus three months of bank statements from them, because the sum is large relative to the buyer's own savings.
Example
A borrower is given $12,000 by an aunt six weeks before applying. The lender treats the money as seasoned because it has sat in the account for more than the required period, but it still asks for a gift letter to confirm no repayment obligation exists.
Example
A seller offers to give the buyer $15,000 towards closing costs and calls it a family gift, having recently become the buyer's brother in law. The lender refuses, since a gift from a party to the transaction is treated as a price concession and must be disclosed and deducted from the purchase price instead.
Formula
Calculation
Debt to income ratio = total monthly debt commitments / gross monthly income
A buyer earns $9,000 a month gross and is purchasing a $420,000 home with a 20% deposit of $84,000. She has saved $54,000, and her parents provide the remaining $30,000, documented by a gift letter. The mortgage is $420,000 - $84,000 = $336,000, and the monthly payment including taxes and insurance comes to $2,430. She also has a car payment and student loan totalling $450 a month.
With the gift: total commitments are $2,430 + $450 = $2,880, so the ratio is $2,880 / $9,000 = 32%, comfortably inside a typical 36% guideline.
If the same $30,000 were instead a family loan repayable over five years at 6%, the monthly repayment would be about $580. Total commitments become $2,430 + $450 + $580 = $3,460, so the ratio is $3,460 / $9,000 = 38.4%, which is above the guideline and would probably cause the application to be declined or resized.
The gift letter therefore changes the ratio by 6.4 percentage points, which is the whole difference between an approval and a refusal in this case.Case study
Seen in the real world.
The following is an illustrative and fictional scenario. Two invented buyers, applying through the equally invented Larkfield Building Society, were $30,000 short of the deposit on a $420,000 home. One buyer's father offered the money, and the couple agreed privately with him that they would pay it back at $500 a month once they had settled in.
They signed a gift letter stating that the money was a gift and that no repayment was expected, because they understood that this was what the lender needed to see. The mortgage was approved on a debt to income ratio of 32%, calculated without the $500 commitment they had actually taken on.
In this fictional example the private arrangement surfaced eighteen months later when the couple applied to refinance and their bank statements showed a standing order to the father. The lender treated the original letter as a false statement, the refinance was refused, and the couple ended up disclosing an undocumented debt on every subsequent application. The illustrative point is that a gift letter is only useful if it is true; had the father simply given the money without conditions, or had the couple bought a cheaper property, neither problem would have arisen.
Watch out
Common mistakes.
- Signing a gift letter for money that both sides quietly expect to be repaid, which is a false statement to a lender rather than a technicality.
- Transferring the money in cash or through several small deposits, which makes the paper trail impossible to follow and often causes the funds to be disallowed.
- Assuming the letter alone is enough, when most lenders also want statements showing the giver held the money and the transfer actually happened.
Questions
People also ask.
Does a gift letter create a tax bill?
The letter itself does not, but the underlying gift may need reporting by the giver if it exceeds the annual exclusion, so the two questions should be handled together.
Can a friend or an employer provide gifted deposit funds?
Some lenders allow it with additional evidence of the relationship, but many restrict gifts to close family, so it is worth confirming before the money moves.
What if the gift arrives after the application is submitted?
Tell the lender immediately, since an unexplained large deposit during underwriting is one of the most common causes of delay or withdrawal of an offer.
