Why Underwriting Wants To Know Where That Deposit Came From
You send in two months of bank statements. A few days later the request comes back: explain the deposit on the fourteenth, and provide documentation of its source.
And it feels like an accusation. It is your account. It is your money. Nobody at the bank asked you this when you opened it.
I want to explain what is actually happening there, because once you understand it, the whole thing stops feeling personal and starts being a five minute errand instead of a fight.
Underwriting is not asking whether you have the money
It can see that you have it. The statement is right there.
What it is testing is whether the money is yours and whether it is going to stay. Those are two different questions from "is the balance big enough," and they are the only two that matter for approval.
Here is the failure they are guarding against. Somebody wants to buy a house, comes up short on the cash to close, and borrows the difference quietly. A relative wires it with a handshake understanding that it gets paid back. Or a personal loan lands in the account and the payment on it never shows up on the credit report until later.
Either way the file now understates what that borrower actually owes, and the payment they were approved for is not the payment they are really going to carry. That is the loan that goes bad in year two. So the rule exists.
What counts as large enough to ask about
There is no single universal figure, and it is not a fixed dollar amount that I can hand you. Different loan types and different investors set the trigger differently, and it is generally scaled to your income or to the loan amount rather than being one flat number.
The practical version: anything that is clearly out of pattern for your account is going to get a question. If your statements show payroll every other Friday and then one deposit that does not look like payroll, expect to source it.
Your regular paycheck does not need sourcing. Neither does a transfer between two of your own accounts, as long as you can show both sides of it.
What sourcing actually means
It means a paper trail from where the money was to where it is now. Usually that is the deposit slip or the transfer record, plus a statement from the account it came out of.
A few common ones and how they resolve.
A tax refund or an insurance settlement. Easy. The notice or the check stub, and it is done.
A transfer from your own savings. The statement from that savings account showing the money leaving. Also easy, and this is the one people forget they can do in about two minutes.
Selling something. A car, a boat, furniture. A bill of sale and, ideally, a copy of the buyer's payment. Cash sales are harder precisely because there is nothing to trace, which is worth knowing before you sell the truck for cash to fund your down payment.
A gift from family. This one has a specific form. A signed gift letter stating the amount, who gave it, the relationship, and critically that it is a gift and not a loan with no expectation of repayment. Usually paired with evidence the donor had the funds and evidence of the transfer. Most loan programs allow gifts from family, so this is routine, not a problem. It only becomes a problem when the money arrives first and the paperwork is assembled backwards.
The two things that actually cause trouble
Cash. Physical currency you deposit has no history. It cannot be sourced, because there is nothing to source it to. Under-the-mattress savings, cash tips that were never deposited, money from a side job paid in cash. It is real money and it is yours and underwriting still cannot use it. If you have cash you intend to use, get it into the bank early, well before you are in a transaction, and let it season.
Moving money around late. Every transfer you make during the process creates another thing to document. If you have five accounts, consolidating them the week before closing turns a simple file into a scavenger hunt. Get the money where it needs to be early, then stop touching it.
How to make this a non-event
Look at your last two months of statements yourself before you ever send them to me. Find anything that is not payroll. For each one, ask whether you could prove where it came from with a document. If the answer is no, tell me about it up front rather than waiting for the file to find it.
That is the whole trick. Every single one of these is solvable, and almost all of them are solvable in a few minutes. What creates the drama is discovering them at day nineteen of a thirty day close, when everybody is already tense and the seller is asking questions.
None of this is anybody accusing you of anything. It is a documentation standard, it applies to everyone, and the underwriter reading your file has never met you and is not forming an opinion about your character. They need a piece of paper.
