Why Your Lender Asks About Large Deposits in Texas
Why Is My Lender Asking Me to Explain a Large Deposit in My Bank Account?
Quick Answer: Your lender has to prove the funds for your down payment and closing costs are really yours. A large deposit could be a hidden loan, and a loan is new debt that can change what you qualify for. So the lender asks for a short signed letter and proof, like a gift letter, a pay stub, or a bill of sale.
Key Takeaways:
Lenders must document where your down payment and closing cost funds came from.
On many conventional loans, a large deposit is one deposit bigger than half your total monthly income.
FHA loans look at deposits bigger than 1% of the home's price or value, or any deposit that doesn't match your normal pattern.
Funds that have sat in your account for two full monthly statements, about 60 days, usually don't need a letter.
Cash kept at home is the hardest deposit to prove, so talk to your loan officer before you deposit it.
You're close to the finish line on your home loan. Then an email shows up. Your lender wants you to explain a deposit in your bank account.
A lot of buyers think something went wrong. Nothing went wrong. A deposit question is one of the most common requests in the whole loan process.
Why the lender cares
Your lender has to know the funds for your down payment are really yours. Your down payment is the part of the home price you pay upfront. Your closing costs are the fees you pay to finish the loan.
If a big deposit came from a friend who wants it back, that deposit is really a loan. A loan is new debt. New debt raises your monthly bills, and higher monthly bills can change how much home you qualify for. Federal rules also require lenders to know where large funds come from. So the underwriter, the person who reviews and approves your loan file, has to check every deposit that looks unusual.
What counts as a large deposit
The answer depends on the loan. As of September 2026, many conventional loans, the loans that follow Fannie Mae rules, count a large deposit as one single deposit bigger than half your total monthly income. If you earn $6,000 a month, a $3,200 deposit can trigger the question. FHA loans flag deposits bigger than 1% of the home's price or value, plus any deposit that doesn't match your usual pattern.
Common deposits and what proves them
Paycheck: your pay stub.
Tax refund: the IRS deposit on your bank statement, plus your tax return if asked.
Gift from family: a signed gift letter, plus proof the funds left the giver's account and landed in yours.
Sold a car: the bill of sale and proof of payment.
Moved funds between your own accounts: statements from both accounts.
Cash: the hardest one. Cash kept at home, or cash a parent hands you to help with the down payment, is tough to trace on paper.
The 60-day rule of thumb
Lenders usually ask for your last two months of bank statements. Funds that have sat in your account for two full statements are called seasoned funds, and seasoned funds usually don't need a letter. That's why timing matters when you're getting ready to buy in Round Rock, Pflugerville, or Leander.
How to answer the request
Keep the letter short. Write the date, the amount, where the deposit came from, and sign it. Attach the proof. Answer fast, because a slow answer can push back your closing date.
What to avoid
Don't move funds between accounts right before you apply. Don't deposit a stack of cash without asking your loan officer first. And never try to hide a deposit. The lender sees every line on your bank statement.

FAQ
What is a letter of explanation for a large deposit? A letter of explanation is a short signed note that tells your lender the date, the amount, and the source of a deposit. You attach proof, like a pay stub, a gift letter, or a bill of sale. Most letters are only two or three sentences long.
Can I use a gift from family for my down payment? Yes, on many loans. The giver usually has to be an approved donor, like a parent or other relative, and sign a gift letter saying you never have to pay it back. You also need to show the transfer from their account to yours, so a check or bank transfer works better than handing over cash.
How long do funds need to sit in my account before I buy a house? Lenders usually review your last two monthly bank statements, about 60 days. Funds that have sat in your account for that whole time are called seasoned funds and usually don't need a letter. Your lender can still ask about any deposit that looks unusual.
Can I use cash my parents gave me for my down payment? It depends on the loan and how well the gift can be documented. Cash handed over in person is hard to trace, and funds a lender can't source may not count toward your down payment. A check or bank transfer from your parents' account, plus a signed gift letter, is much easier to prove, so talk to your loan officer before anyone deposits cash.
