Borrower statement that clarifies a mortgage underwriting question or document inconsistency.
A letter of explanation is a borrower statement that clarifies a mortgage underwriting question, document gap, or file inconsistency.
A letter of explanation matters because not every underwriting question can be answered by a form field or account statement alone. The lender may need the borrower’s explanation for a Large Deposit, Credit Inquiry, Employment Gap, address mismatch, or other file detail that needs context.
It also matters because borrowers often read the request as a sign that the file is in trouble. Usually, it means the underwriter needs a clear, documented explanation before deciding whether the issue is acceptable.
Borrowers usually encounter letters of explanation during underwriting or while clearing Conditions to Close.
The term becomes practical when the lender asks for a short written statement that connects the facts in the file. A good explanation should be direct, factual, and consistent with the supporting documents.
| Trigger | What the lender is trying to clarify |
|---|---|
| Large deposit | Whether the money is acceptable and not undisclosed borrowed funds |
| Credit inquiry | Whether the borrower opened or plans to open a new debt |
| Employment gap | Whether the work history still supports usable income |
| Address mismatch | Why the borrower’s documents show different residential histories |
| Document inconsistency | Why two file documents appear to tell different stories |
The letter should not invent an explanation or overstate certainty. It should match the file and any documentation being supplied.
A bank statement shows a recent deposit that does not match normal payroll. The lender asks for a letter of explanation. The borrower states that the money came from selling a vehicle and supplies matching sale documentation.
A letter of explanation differs from Conditions to Close because it is one possible item used to satisfy a condition, not the entire list of outstanding requirements.
It differs from Verification of Assets because asset verification confirms funds and account details, while the letter explains a question or inconsistency around the facts.
It also differs from Loan Denial. A request for an explanation is not the same as a denial; it is usually a request for clarity before the lender makes or finalizes a decision.
