If you think an automated mortgage decision used incorrect or incomplete information, first get the lender’s adverse-action notice and the specific reasons for the decision. Then check the underlying credit report and application file, dispute any reporting errors with the relevant companies, send documented corrections to the lender, and ask what review or reconsideration process applies. A request for reconsideration is not a guarantee that the lender must reverse its decision or provide a particular appeal process.

1. Get the adverse-action notice and the specific reasons

Ask the lender for the adverse-action notice if you have not received it. The notice should give the main reasons for the denial or explain how to request them. If it provides a route to request the reasons, follow the instructions and stated deadline; CFPB consumer guidance identifies a 60-day period in that context. CFPB: What should I do if my mortgage application is denied?

If the lender relied on a credit report, the notice should identify the credit reporting company and explain how to obtain a free report from that company within 60 days of the notice. Get that report promptly so you can compare its contents with the lender’s reasons.

Do not settle for a vague explanation such as “the system declined your application” or “you did not meet internal standards.” Ask the lender to identify the actual principal factors and the information behind them if the reasons are unclear or do not match your application. CFPB guidance says creditors must provide specific, accurate reasons for adverse action even when they use complex or opaque algorithms; an unexplained score or internal standard is not a substitute.

2. Work out which information may be wrong

Compare the stated reasons with your mortgage application, documents submitted to the lender, and the credit report if one was used. Look for mismatches such as:

  • Incorrect identity details or accounts that belong to someone else.
  • Balances, payment history, account status, or inquiries that are inaccurate.
  • Income, debts, or other application details entered incorrectly or left incomplete.
  • Property information or documents associated with the wrong borrower, account, or property.

This is a practical check, not a claim that every item affected your decision. Ask the lender which information and factors it actually considered before assuming that a particular error caused the denial.

3. Dispute errors in a credit report

If the credit report contains inaccurate information, dispute the item with both the credit reporting company and the company that supplied the information, such as a creditor. Describe exactly what is wrong and include copies of records that support your correction. Keep copies of everything you send and note the dates.

The CFPB says a reporting company must investigate and correct errors it finds. If an investigation does not resolve an item you still believe is wrong, CFPB guidance says you may generally add a statement to your report. For a credit-reporting problem that remains unresolved, you can submit a complaint to the CFPB. CFPB: Mortgage denial and credit-report guidance

4. Send corrections to the lender and ask about reconsideration

Correcting a credit report does not by itself ensure the lender will reopen or approve an application. Send the lender the specific corrected information and supporting documents, using the loan officer or review contact it identifies. Ask whether it can reconsider the application using the corrected information and what process and timing apply to that lender and loan program.

Useful questions include:

  • Can the application be rerun or reviewed with the corrected information?
  • Are any additional documents required, and where should they be submitted?
  • What is the deadline for submitting corrections or requesting review?
  • Could a new review affect a rate-lock term or another application deadline?

These are practical questions, not a guaranteed legal appeal route. The sources cited here do not establish a universal requirement that lenders offer a formal appeal, provide human review in every case, manually underwrite every file, or reverse an automated result.

5. Use the route that matches the problem

What may be wrong Practical next step
Inaccurate credit-report information Dispute with the credit reporting company and the information provider; document the dispute and supporting records.
Incorrect or incomplete information in the lender’s file Send evidence to the lender and ask whether it can reconsider or rerun the application.
Possible discrimination in the denial or offered terms Preserve relevant facts and documents, then use an appropriate fair-lending complaint route.
A mistake in mortgage servicing after origination Determine whether it is a covered servicing error under Regulation X; do not treat it as the same issue as an underwriting denial.

If you suspect discrimination

A factual data error and possible discrimination are different concerns. The FTC explains that the Equal Credit Opportunity Act and Fair Housing Act provide protections relevant to mortgage applications and terms. A denial alone does not establish discrimination; preserve the application, notices, communications, and other facts that may help explain what happened, and consult the FTC’s guidance on mortgage discrimination and complaint options. FTC: Mortgage discrimination

If the problem is mortgage servicing

Do not assume that sending a mortgage servicer a Regulation X notice of error will trigger the servicing investigation process for an origination or underwriting denial. CFPB’s official interpretation of Regulation X § 1024.35 excludes errors relating to mortgage origination or underwriting from the covered error categories. The provision may still matter for a distinct, covered servicing error after origination. CFPB Regulation X § 1024.35 and official interpretation

What “automated mortgage decision” can mean

The phrase can refer to different tools, and the right correction depends on which one was involved:

  • Automated underwriting: A system evaluates borrower and loan information. For FHA-insured loans, HUD describes FHA TOTAL as a statistically derived algorithm accessed through an Automated Underwriting System; TOTAL is not itself an AUS. In that FHA context, “Accept” means FHA will insure the loan without manual underwriting review except where the FHA handbook requires a manual downgrade. These FHA-specific terms should not be generalized to other loan programs. HUD: FHA TOTAL Mortgage Scorecard
  • Credit report or score: This concerns reported credit history and other credit information. If the report is inaccurate, use the credit-report dispute route described above.
  • Automated valuation model (AVM): An AVM estimates property collateral value; it is not a complete decision about a borrower’s creditworthiness. FHFA summarizes a federal final rule requiring quality-control standards for certain AVM uses, including confidence in estimates, protection against data manipulation, conflict-of-interest controls, random sample testing and reviews, and compliance with nondiscrimination laws. The rule took effect October 1, 2025; it does not establish a borrower appeal procedure for an underwriting denial. FHFA: AVM quality-control final rule
