Why This Letter Changes Lender Decisions

Most underwriters are trained to look for patterns, not one-time mistakes. A good explanation letter removes guesswork from your application file. It shows you take responsibility, understand what went wrong, and have fixed the root issue.

This letter is not an excuse—it is proof you are now a reliable borrower. Lenders receive hundreds of applications every week. A clear, honest letter will make your file stand out for all the right reasons. Every letter should include these core elements:

  • Exact dates of the negative credit event
  • Clear, factual reason for the issue
  • Steps you took to fix the problem
  • Proof the issue will not happen again

Not all bad credit is treated the same. The table below shows how lenders view different reasons for low scores:

Credit Issue Lender Perception
Medical emergency Very low risk
Job layoff Low risk
Divorce Moderate risk
Overspending High risk

Sample Letter Explaining Bad Credit to Lender: Unexpected Medical Bills

Date: 10/12/2024

To: Underwriting Department
First National Home Loans

Dear Loan Officer,

I am writing to explain the 3 late payments on my credit report from March to May 2024. During that time, my child required emergency appendectomy surgery and 2 weeks of hospital care. We had not met our annual insurance deductible at that time.

I set up a payment plan with the hospital once we returned home, and all medical bills are now current. We have also increased our emergency savings to cover future unexpected costs. This situation will not repeat.

Thank you for reviewing my application.
Sincerely,
Maria Gonzalez

I appreciate your consideration.

The single late payment showing on my credit report is from 7 years ago, when I was 19 years old and working my first part time job. I mismanaged my first credit card and missed one payment.
