You sent in your mortgage application, uploaded bank statements, maybe answered a few follow-up questions, and then the message lands in your inbox: the underwriter needs a credit inquiry explanation letter.
Most borrowers read that and assume something is wrong. Usually, it's not. It's a normal underwriting condition, especially when your credit report shows several recent hard pulls and the file doesn't explain what they were for.
For self-employed borrowers, 1099 earners, investors, and ITIN borrowers, this request shows up even more often because underwriters already need more context to understand the full file. A clean, direct letter can settle the issue fast. A vague one can drag the loan out for days. If you want help with your situation, you can schedule a call.

Why Lenders Ask for a Credit Inquiry Explanation Letter
When an underwriter asks for a credit inquiry explanation letter, they're trying to answer one practical question: did these inquiries lead to new debt, or were they part of a legitimate shopping process?
That distinction matters. A few recent inquiries might mean you were comparing mortgage offers. They might also mean you applied for several new credit accounts right before asking a lender to approve a home loan. The credit report shows the inquiries, but it doesn't show your intent. The letter fills in that gap.
What the underwriter is trying to confirm
Underwriting is built around documentation. If a report shows multiple inquiries close together, the underwriter wants the file to explain:
- Who pulled credit: the creditor or lender name
- When it happened: the inquiry date
- Why it happened: rate shopping, pre-approval, refinance comparison, or another factual reason
- What resulted from it: whether any new account was opened or no new debt was incurred
Underwriting guidelines, such as those from Fannie Mae, emphasize that explanation letters must be brief and factual. They help underwriters distinguish legitimate rate shopping from risky behavior, which is critical for loan approval, especially as conforming loan limits are projected to rise to $832,750 in 2026 according to Guaranteed Rate's explanation of mortgage explanation letters.
If you're trying to understand how lenders look at your report overall, it helps to review how mortgage lenders evaluate credit.
Why this request is usually routine
Borrowers often overreact to this condition because the wording sounds formal. In practice, a credit inquiry explanation letter is often just the underwriter asking you to connect the dots.
Practical rule: The letter isn't there to defend your character. It's there to document the file.
That's especially true when the inquiries came from mortgage lenders. Shopping for terms is normal. Underwriters need the record to show that the inquiries were tied to one financing purpose and didn't create undisclosed monthly obligations.
A good way to think about it is this. Your credit report is the raw data. The explanation letter is the caption. If the caption is clear, the file moves. If the caption is vague, the underwriter has to come back for more.
The Anatomy of an Effective Explanation Letter
A strong credit inquiry explanation letter is short, businesslike, and complete. It doesn't read like an essay. It reads like a clean answer to a specific underwriting question.
The non-negotiable pieces
A compliant Letter of Explanation contains three essential components: an acknowledgment of the inquiries, including dates and creditor names, a factual reason for them, and a clear confirmation that no new personal debt was incurred as a result, as described in this LOE guidance discussion on myFICO Forums.
That core content should sit inside a standard business-letter format. In plain terms, your letter should include:
| Part | What belongs there |
|---|---|
| Header | Your full name and contact information |
| Date line | The date you sign the letter |
| Recipient details | Lender or loan officer name, if provided |
| Subject line | RE: Your full name and loan application number |
| Body | The explanation itself |
| Closing | Signature and typed legal name |
A lot of borrowers want to add background, personal stress, or a long timeline. That usually hurts more than it helps. Underwriters don't need a narrative arc. They need a clean answer they can attach to the file.
A simple lender-ready structure
The best letters usually follow a tight sequence.
Acknowledge the request
State that you're responding to the underwriter's request for explanation of recent credit inquiries.Identify the inquiries
List the creditor names and dates. If there were several tied to mortgage shopping, say that directly.State the reason
Use factual language such as “I was shopping for a competitive mortgage rate” or “I authorized these inquiries during the pre-approval process.”Confirm the outcome
This is the sentence many borrowers forget. State whether any new account was opened. If no debt resulted, say so plainly.Attach support if needed
If an inquiry was unauthorized or needs added clarification, note the related documents.
Keep the letter tight. If a sentence doesn't help the underwriter clear the condition, cut it.
Here's the type of wording that works:
I am writing in response to the request for explanation of recent credit inquiries on my credit report. The inquiries from ABC Mortgage dated January 10 and XYZ Home Loans dated January 12 were authorized as part of my mortgage rate shopping process. No new revolving or installment debt was opened as a result of these inquiries.
That's the tone you want. Clear, factual, and easy to underwrite.
Crafting Your Letter From Start to Finish
Most problems with a credit inquiry explanation letter start before the writing starts. Borrowers rely on memory, guess at dates, or answer a broader question than the underwriter asked. A better approach is to draft from documents.
Start with the report, not your memory
Pull up the credit report the lender referenced and the exact underwriting condition. Then build your letter around those items only.
A successful LOE follows a clear methodology: address the letter correctly, create a subject line with your name and loan number, acknowledge the request, provide factual details of the inquiry, attach supporting documents if needed, and sign with your full legal name. Brevity is key, with successful letters often staying under 200 words, according to LendingTree's guide to mortgage explanation letters.
If you're still gathering your loan file, this overview of mortgage documentation in the early stage of the process helps you line up what underwriters usually ask for.
Before you draft, verify these items:
- Exact inquiry names: match the creditor names shown on the report
- Correct dates: don't approximate
- Loan number: use the application number on file
- Result of each inquiry: account opened, no account opened, or unauthorized inquiry
- Any backup documents: dispute letters, creditor emails, or proof of cancellation
A base template that works
You don't need fancy wording. You need wording that closes the loop.
Use this base structure:
Date
Lender Name
Loan Officer NameRE: Full Name, Loan Application #
I am writing in response to the underwriter's request for an explanation of recent credit inquiries appearing on my credit report.
The inquiries from [Creditor Name] on [Date] and [Creditor Name] on [Date] were authorized by me for the purpose of [mortgage pre-approval, rate shopping, auto financing comparison, etc.].
No new personal debt was incurred and no new account was opened as a result of these inquiries.
Please let me know if any additional information is needed.
Sincerely,
Full Legal Name
Signature
If one inquiry was unauthorized, say that directly and note the action taken. Don't soften it with vague language. “I did not authorize the inquiry and submitted a dispute” is stronger than “I believe this may have been an error.”
Final review before you send it
A last review catches most avoidable problems. Read the letter once like a borrower, then once like an underwriter.
Check for:
- Consistency: names and dates must match the report
- Tone: remove emotional or defensive wording
- Completeness: include the no-new-debt statement if true
- Formatting: sign it exactly as your application shows your name
- Attachments: only include documents that support the explanation
One practical note. New American Funding, LLC. is one option among lenders and mortgage teams that may allow borrowers to submit a written statement explaining items on a credit report as part of the file review process. What matters most is that the statement directly answers the condition and matches the rest of the file.
Tailoring Your Letter for Different Borrower Profiles
Generic templates leave out the part that matters most for non-traditional borrowers: how the inquiry pattern fits the way you qualify. That's where many letters fall apart.
A major gap in most guidance is failing to explain how to frame multiple mortgage pre-approvals as rate shopping rather than debt accumulation. Data indicates 18% of denied loans were due to credit concerns, often from unexplained inquiry patterns, a problem especially acute for self-employed borrowers, according to Society Mortgage's discussion of credit inquiry letters.
Self-employed and 1099 borrowers
Self-employed borrowers often talk to more than one lender because the available programs can differ a lot. One lender may look at tax returns. Another may allow bank statements. Another may review a profit and loss statement. The inquiry pattern can look messy on paper even when the borrower is acting responsibly.
If you're using a bank statement loan, the context matters. A 12-month bank statement mortgage program for self-employed borrowers may require at least 20% down payment, uses bank deposits instead of tax returns or traditional income documents, and does not require federal income tax returns in the standard way, based on Gustan Cho's Non-QM overview. That means borrowers often compare several options before choosing a program.
A stronger explanation sounds like this:
The inquiries shown on my credit report were authorized during my search for a mortgage program compatible with self-employed income documentation. I compared lending options that evaluate bank statement income. No new personal debt was incurred from these inquiries.
For some bank statement Non-QM loans, the typical allowable debt-to-income ratio is 50%, credit scores can go as low as 620, borrowers with scores of 720+ may secure up to 90% financing, and borrowers near 620 may need 25% down payment, according to Deephaven Mortgage's Non-QM loan requirements. That program variability is exactly why self-employed borrowers often have several legitimate mortgage pulls close together.
Real estate investors and DSCR borrowers
Investors should avoid writing the letter as if they were scrambling for money. The better framing is portfolio-related financing activity.
Say what the inquiries were tied to. Keep it tied to acquisition, refinance analysis, or lender comparison for an investment property. If the inquiry did not produce a new consumer obligation, say that clearly.
Good sample phrasing:
The inquiries from the listed mortgage lenders were authorized in connection with financing review for an investment property. I was comparing lending terms and program fit. These inquiries did not result in new personal consumer debt.
That distinction matters because an investor file is often underwritten differently from an owner-occupied W-2 file. The underwriter still wants to know whether your personal obligations changed.
ITIN and other non-traditional borrowers
ITIN borrowers sometimes have thinner credit files, newer tradeline patterns, or a mix of inquiry types that need more context. Keep the explanation practical and straightforward. Don't try to educate the underwriter on your whole credit history.
If your inquiry pattern came from trying to identify a lender that accepts your documentation profile, say that. If you were seeking a mortgage option as an ITIN borrower and no account was opened from those inquiries, make that the center of the letter.
For foreign national Non-QM loans, borrowers may need a visa or visa waiver and three open and active trade lines with at least two years of history, while lenders may use bank statements, profit-and-loss statements, or assets rather than W-2s and tax returns, according to Truss Financial Group's Non-QM foreign national loan overview. Files like these naturally generate more lender comparisons because qualification paths vary.
How to frame mortgage rate shopping correctly
This is the sentence pattern I'd use most often when the inquiries came from mortgage lenders:
- Short version: I authorized these inquiries while shopping for a competitive mortgage rate, and no new debt was incurred.
- More specific version: These inquiries were authorized during my mortgage pre-approval and rate comparison process with different lenders. I did not open any new non-mortgage credit account as a result.
- For complex files: These inquiries were part of my effort to identify the mortgage program that fit my income documentation and property goals. No new personal debt resulted from the inquiries listed.
A clean explanation ties the inquiries to one financing purpose. It doesn't leave the underwriter guessing whether you were opening new obligations elsewhere.
Common Mistakes That Delay Approvals and How to Avoid Them
Borrowers often assume any explanation is better than none. That's not true. A weak letter can create more follow-up than the original condition.
What borrowers get wrong most often
Failing to specify if an inquiry was authorized or unauthorized leads to 25% of underwriter delays. Using emotional language can reduce approval odds by 35%, and failing to attach evidence can stall 42% of LOEs, according to Herring Bank's discussion of mortgage explanation letter pitfalls.
That lines up with what shows up in real files. The most common mistakes are:
- Vague wording: “I was checking options” doesn't explain enough.
- Emotional tone: frustration, blame, or overexplaining creates noise.
- Missing status: many borrowers forget to state whether a new account was opened.
- No support for exceptions: unauthorized inquiries usually need backup.
- Too much information: extra personal detail invites fresh questions.
What to do instead
Use a tighter standard.
- State authorization clearly: say whether you authorized the pull or did not.
- Anchor to the report: use the exact lender names and dates shown.
- Close the loop: confirm whether new debt was incurred.
- Attach only relevant support: dispute letter, creditor note, or similar evidence when needed.
- Keep the tone neutral: factual language reads better in underwriting.
Here's a quick comparison:
| Weak wording | Better wording |
|---|---|
| “I was scared because my score changed.” | “The inquiry was authorized during mortgage rate shopping.” |
| “I think this was a mistake.” | “I did not authorize this inquiry and submitted a dispute.” |
| “I checked with several places.” | “The inquiries from the listed mortgage lenders were part of my pre-approval comparison.” |
Underwriters clear facts faster than feelings.
If your first draft sounds like you're arguing, rewrite it. If it sounds like a file note, you're probably close.
Submitting Your Letter and What Comes Next
A clean explanation letter can clear in one underwriting pass. A messy one often comes back with another condition, another document request, or a call from your loan officer asking what the inquiry was for.
Submit the letter exactly how your lender requests it, usually through the borrower portal or by email to your loan contact. Underwriters want one clear response they can match to the condition, the credit report, and the rest of the file without sorting through loose documents.
How to submit it cleanly
Send a single package.
That package should include the signed letter and any document the letter references, such as a creditor email, dispute confirmation, or proof that no new account was opened. Save everything as PDF if possible. It keeps the formatting consistent and reduces back-and-forth over missing pages or unreadable phone screenshots.
If you want context on where this review happens, see this overview of the mortgage underwriting stage.
A few habits help keep the file moving:
- Send it quickly: inquiry conditions are usually simple, but they can hold up a clear-to-close if they sit unanswered
- Name files clearly: use labels like
Credit Inquiry Letter - John Smith.pdfinstead ofdocument1.pdf - Match your application: your name, property address, and signature should line up with the loan file
- Keep each letter focused: if underwriting asked about credit inquiries, do not combine that response with job history, bank deposits, or tax return issues
For self-employed, 1099, investor, and ITIN borrowers, this matters even more. Those files already ask the underwriter to review more moving parts, so a precise response helps avoid extra scrutiny on unrelated parts of the application.
What the underwriter usually does next
After submission, the underwriter compares your letter to the inquiry dates, creditor names, and any new accounts showing on the report. The main question is simple: did this inquiry lead to new debt that changes your qualification?
If the answer is clear and supported, the condition may be signed off with no further action. If the letter is vague, if dates do not match, or if the report suggests a new obligation that the file does not explain, expect another condition.
I see this often with non-traditional borrowers. A self-employed borrower may have a business credit pull that looks personal until it is explained properly. A real estate investor may have several inquiry lines tied to property financing that never closed. An ITIN borrower may need to clarify that a pull was related to a rental application or an account review, not new consumer debt. Those are underwritable issues, but only if the letter answers the question directly.
New American Funding, LLC. helps borrowers through mortgage scenarios that often require extra documentation, including alternative-income and non-QM files. In practice, the borrowers who get through this stage fastest are usually the ones who submit a short letter, clean support, and nothing extra.
