A letter of explanation for an address is a short, signed statement you send your mortgage lender to account for any address on your application or credit report that doesn’t line up with where you actually lived. One page is enough. It should name you, reference your loan number, list each address with the months and years you lived there, explain the mismatch in a sentence or two, and come with documents that back up what you say.
What the Letter Needs to Say
The request almost always comes from the Uniform Residential Loan Application, which asks for two years of address history. When what you wrote doesn’t match the credit bureaus’ records, the underwriter needs a written explanation before the file can move.1Fannie Mae. Uniform Residential Loan Application
Underwriters read a lot of these letters. The ones that clear quickly are short, specific, and don’t wander into anything that wasn’t asked about. Include:
- Your full legal name and the date at the top of the page.
- Your loan or application number, which appears on your loan estimate or the lender’s earliest correspondence.
- Each address at issue, with the exact start and end dates (month and year) you lived there.
- A plain factual explanation of the discrepancy. One or two sentences per address.
- Your phone number and email so the underwriter can reach you directly.
Keep the tone factual. You are not making a case or telling a story. If you moved between apartments and used a relative’s address for mail during the gap, say so. If a credit report shows an address you never lived at because of a data entry error, say that instead. The underwriter needs enough to check a box and move the file forward.
A Sample You Can Adapt
Replace the bracketed items with your own details:
[Your Full Name]
[Your Current Address]
[Date]
[Lender Name]
[Lender Address]
Re: Loan Number [XXXXXX]
To Whom It May Concern:
I am writing to explain the address discrepancy identified during underwriting of my mortgage application. From [month/year] to [month/year], I lived at [address]. I then moved to [address] in [month/year], where I currently reside. During the transition, my mail was forwarded to [address], which is my [parent’s/relative’s/P.O. Box] address. This is why [that address/multiple addresses] appear on my credit report.
I have attached [utility bills/lease agreement/other documents] confirming my residency at each location. Please contact me at [phone] or [email] if you need anything further.
Sincerely,
[Your Name]
If the issue is a typo rather than a real move, the body can be even shorter: “The address at [incorrect address] on my credit report appears to be a data entry error. I have never lived at that location. My correct address during that period was [correct address].”
Common Situations That Trigger the Request
Most address discrepancies come from one of a few ordinary circumstances. Writing the explanation is easier once you know which one fits:
- A recent move the credit bureaus haven’t caught up with, because creditors update on their own schedules.
- A P.O. Box used as a mailing address. Federal banking rules require a residential or business street address for individual accounts, so a P.O. Box alone prompts questions about where you actually live.2eCFR. 31 CFR 1020.220 – Customer Identification Programs for Banks
- Clerical errors on the credit report, like a transposed house number or misspelled street name, that create an apparent second address.
- Temporary living arrangements: staying with family, extended work travel, or splitting time between two homes, which leave no paper trail.
Documents to Attach
A letter alone sometimes clears a typo, but most underwriters want proof. The strongest documents tie your name to a physical address during a specific window of time:
- Utility bills (electric, water, gas) are the most useful because they’re tied to a meter at a specific property. Try to cover the dates in question.
- A signed lease showing your name, the property address, and the term directly confirms where you lived and when.
- A voter registration card linked to the address serves as government-sourced proof.
- A driver’s license or state ID showing the address helps, though it only shows what you reported to the DMV, not necessarily the dates you lived there.
- Bank or credit card statements mailed to the address build a timeline when utility bills aren’t available.
Combine the letter and all attachments into a single PDF before uploading. Underwriters work from digital files, and splitting evidence across multiple uploads makes it easy for a page to get lost.
How to Submit and What Happens Next
Most lenders have a secure portal for uploading the letter and attachments directly. If yours asks for physical copies, send them by certified mail with a return receipt. Either way, keep your own copies.
Initial underwriter review generally takes about three business days, though that varies with the lender’s volume and the complexity of your file.3Wells Fargo. Key Steps to Understand Mortgage Underwriting If the underwriter is satisfied, the file moves toward closing. If not, you’ll receive a conditional approval listing exactly what else is needed.4U.S. Bank. Mortgage Underwriting Process – How Long Does It Take Respond within 48 hours whenever you can. Slow responses to conditions are a leading reason closings get pushed back.
If you don’t respond, or your response doesn’t address the concern, the lender can suspend the application. That isn’t the same as a denial, but your file stops moving until you provide what was asked for.
Keep It Truthful
The letter becomes part of your permanent loan file, and what you write in it can be compared against tax records, insurance policies, and credit data for years after closing. Occupancy fraud, meaning claims that you’ll live in a property as a primary residence when you actually intend to rent or invest, carries real consequences: a lender who later discovers misrepresentation can accelerate the loan, making the entire balance due immediately. Making a false statement on a mortgage application is also a federal crime under 18 U.S.C. ยง 1014, with penalties of up to 30 years in prison and a fine of up to $1,000,000.5Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally
Treat the letter as what it is: a formal statement to a federally regulated institution. Keep it honest, keep it short, and attach the documents that prove what you said.
