How to write a mortgage letter of explanation

An LOE request is not bad news. It means underwriting sees something in your file they can't fully explain from the documents alone, and they want a brief note to close the gap. Most LOEs resolve in a single round if they're written clearly and paired with the right supporting document.

The problem is that borrowers often write LOEs that are too long, too vague, or unaccompanied by documentation. The result is a second condition asking for more.

When LOEs are required

Underwriting requests LOEs for situations that look unusual from a document-only review. Common triggers:

Large deposits. Any deposit that's roughly 50% or more of the monthly qualifying income. The question isn't whether the deposit is legitimate, it's whether underwriting can trace it to a documented, acceptable source. This is also one of the more preventable LOE triggers — catching large deposits before submission often avoids the condition entirely.

Employment gap. A break in employment history (even a few months) shows up in the documentation and needs a brief explanation of what happened and when employment resumed.

Address discrepancy. If the borrower's ID, tax returns, and bank statements show three different addresses, underwriting may ask for a brief note clarifying their housing history.

Credit inquiry. Any new credit inquiry in the last 90 days may require an explanation of what the inquiry was for and whether new debt was taken on.

Recent job change. A job change within the last 12 to 24 months sometimes triggers a question about employment stability, particularly if the income type changed (hourly to salary, salary to commission, W2 to self-employed).

Late payment or collection. A late payment in the last 12 to 24 months, or a collection account, will almost always generate an LOE request.

Business funds used for personal purposes. For self-employed borrowers, large transfers from a business account to a personal account may trigger a question about the nature of the transfer.

What makes a good LOE

A good LOE is short, factual, and forward-looking. It answers exactly what was asked and nothing more.

Short. One to three paragraphs is enough for any scenario. Longer letters introduce new questions.

Factual. Dates, amounts, and account names when relevant. "I received a $6,400 wire transfer from my mother on January 10, 2026" is cleaner than "I received a large gift from my family."

Forward-looking. For credit events especially, a brief note that the situation has been resolved (paid off, no longer employed there, moved) helps underwriting clear the condition with less follow-up.

Paired with a supporting document. Almost every LOE is stronger with a document attached. A large deposit LOE plus a bank transfer confirmation is one condition. A large deposit LOE alone is likely two (the first asking for the letter, the second asking for proof).

What to avoid: emotional explanations, blame, vague assurances ("everything is fine now"), and anything that introduces new information underwriting didn't already ask about.

LOE templates by scenario

Use these as starting points. Adjust names, dates, and amounts. Borrowers should sign and date the letter.

Large deposit:

"The $[amount] deposit that appears in my [BankName] account on [date] is a [tax refund / bonus from employer / transfer from my savings account at another bank / sale of personal property]. I have attached [the IRS transcript / my employer bonus statement / a transfer confirmation / a bill of sale] as documentation of the source of these funds."

Employment gap:

"From [start date] to [end date], I was not employed. During this period, I [was laid off and searching for new work / took time off to care for a family member / left voluntarily to relocate]. I resumed full-time employment with [employer name] on [start date of current job]."

Address discrepancy:

"The addresses shown across my documents reflect my housing history over the past two years. From [date] to [date], I lived at [address 1]. I moved to [address 2] on [date], where I currently reside. The difference in addresses on my tax returns and bank statements reflects this transition."

Credit inquiry:

"The credit inquiry from [lender/company name] dated [date] was for [a car loan / a personal loan / a credit card]. I did [not proceed with / did proceed with] that application. No new debt was taken on [or: a new account was opened with a balance of $X, which is not reflected in the documents previously submitted]."

Late payment:

"The late payment on my [account type] account in [month/year] occurred because [brief factual reason, e.g., the account was in dispute, I was between jobs, a payment was lost in a banking transition]. This has since been resolved and I have maintained on-time payments since [date]."

Self-employed business transfer:

"The $[amount] transfer from my business account (held at [bank]) to my personal account on [date] represents [my regular monthly draw / a distribution from business profits for the purpose of [reason]]. This transfer did not negatively affect the operating balance of the business."

Pairing the LOE with the right documents

Here's a quick reference for what supporting documentation typically accompanies each LOE type:

• Large deposit: bank transfer confirmation, check copy, tax transcript, award letter, bill of sale
• Employment gap: offer letter or first paystub from new employer, if available
• Address discrepancy: no specific doc usually required, but a lease agreement or utility bill may help
• Credit inquiry: no specific doc required unless new debt was opened, in which case a statement showing the balance
• Late payment: payoff or payment history from the creditor, if the account is now current
• Business transfer: business bank statement showing pre-transfer balance (for self-employed borrowers)

The goal is one clean LOE plus one supporting document per condition. That's what closes the loop in a single round. A conditions tracker makes it easy to see which LOEs are pending and which have been cleared.
