Bank statements carry a lot of weight in a mortgage file. They show assets and reserves, and the deposits are often the first place an underwriter sees income arrive. That makes them a common target. In Fannie Mae data for 2024, income accounted for 46% of misrepresentation findings, as reported by National Mortgage News.
Editing a statement has never been easier. A PDF editor can change a balance in seconds, and generative AI can produce a convincing statement from scratch. Here is what to look for.
Signs on the page
- Totals that don't reconcile. Opening balance, plus deposits, minus withdrawals, should equal the closing balance. Edited statements often change one figure and forget the others.
- Font and spacing mismatches. A changed amount may use a slightly different font, weight or letter spacing from the numbers around it, or sit a pixel off the column.
- Deposits that look too tidy. Round-number payroll deposits, identical amounts on irregular dates, or payroll arriving on weekends and bank holidays deserve a second look.
- Details that change between pages. Account numbers, names, addresses and statement periods should match on every page.
Signs in the file
- Metadata that doesn't fit the source. A statement downloaded from a bank usually names the bank's document system as its creator. A file last saved by a PDF editor or image tool, or modified after the statement date, is worth checking. Missing metadata alone proves nothing, since many apps strip it.
- A text layer that disagrees with the image. When the text you can select differs from the text you see, part of the page has been changed.
- A "scan" that is too clean. A statement presented as a scan but built from perfectly crisp digital text was probably not scanned.
Signs across the loan file
Compare the statement with everything else the borrower sent. Deposits should line up with pay stubs and W-2s, employer names should match, and statement periods should run on without gaps. A statement that looks clean on its own can still disagree with the rest of the file.
What to do when something looks wrong
A flag is a reason to look closer, not proof of fraud. Files are edited for innocent reasons, such as cropping a scan or removing a password.
- Write down what you saw and where, so the next reviewer can follow it.
- Ask for the original statement, ideally straight from the bank, or verify the account through a direct verification service.
- Don't share suspicions with the borrower before the verification comes back.
- Escalate to your fraud team if the original confirms the edit.
How Trustable helps
Trustable checks each bank statement for edited text, font and layout mismatches, metadata gaps and totals that don't add up, and marks where each finding is on the page and how strong it is. Your underwriter or fraud team decides what happens next. No AI is 100% accurate, so every flag is shown with its evidence.
