A letter of explanation is a short, signed note that tells your mortgage lender the story behind something in your file, like a late payment or a large deposit. Underwriters ask for them all the time. Keep it short, factual and specific.
What lenders ask about most
| Topic | What the lender wants to know |
|---|---|
| Late payments | Why it happened and why it won't happen again |
| Collections and charge-offs | What the debt was and whether it's paid, settled or disputed |
| Credit inquiries | Whether you opened new credit that isn't on your application yet |
| Employment gaps | Why you weren't working and that your income is steady now |
| Large deposits | Where the money came from, so they can confirm it isn't a hidden loan |
| Address differences | Why another address shows on your credit report |
How to write a good one
- Answer only what they asked. One letter per issue unless the lender says otherwise.
- Stick to facts and dates. Name the account, the month and what happened.
- Show what changed. On-time payments since, a new job, automatic payments.
- Attach proof when you have it, such as a gift letter, a paid-in-full letter or a hospital bill.
- Sign and date it. Every borrower on the loan should sign.
- Tell the truth. Lenders check, and a false statement on a mortgage application is a federal crime.
Explaining a credit inquiry
If the inquiry led to a new account, give the lender the account details so they can include the payment. If it didn't, say so: for example, that you were shopping for a car loan and didn't take one. Several mortgage or auto inquiries within a short window are usually counted as one by scoring models.
Explaining a large deposit
Say where it came from and attach the paper trail: a gift letter from a relative, a bonus on your pay stub, a tax refund, or a sale receipt. Lenders need to know it isn't a loan you'll have to repay.
