A mortgage application may be evaluated by an automated underwriting system, a person, or a combination of tools and human review. An automated recommendation is not automatically the lender’s final decision. If you are denied or given conditions you do not understand, focus on the lender’s stated reasons, check the information it used, and ask what review or correction options it offers.
What “automated underwriting” means—and what it does not
Automated underwriting uses an electronic tool to evaluate mortgage application information. Lenders may also use manual underwriting, credit models, or a mix of approaches. The CFPB’s ECOA examination procedures ask how a lender uses these methods; they do not establish one workflow for every lender or borrower.
Federal HMDA rules define a covered automated underwriting system (AUS) for specific mortgage-reporting purposes. In covered circumstances, a lender reports the system’s name and result. That regulatory definition is not a complete description of every automated tool a lender might use internally.
An AUS result and the lender’s decision are not necessarily the same thing. A recommendation may inform the lender’s review, but the available federal sources do not establish that every recommendation is final—or that every applicant receives human review. Ask the lender what the result means for your particular application.

How automated and human review can differ
| Approach | What it describes | What to confirm with the lender |
|---|---|---|
| Automated underwriting | An electronic system evaluates application information and returns a result used in the lender’s process. | Which system or result was used, what it means, and whether a person reviewed the file. |
| Manual underwriting | A person evaluates the application without relying solely on an automated system result. | Whether the lender offers this for your loan and what documentation or criteria it requires. |
| Combined process | A lender uses automated tools, credit models, and human review in some combination. | Which parts of your application were reviewed by a person and what information drove the outcome. |
This comparison describes broad approaches, not a promise about a specific lender’s workflow. The reviewed federal materials do not establish a general right to require manual underwriting or a second human review after an automated result.
What to ask if you are denied or receive conditions
- Read the adverse-action notice and identify the principal reasons the lender gives for its decision.
- Ask the lender to explain any reason you do not understand, and whether it can identify missing or inaccurate information in your application.
- Ask whether a person reviewed your file, what role any automated result played, and whether the lender accepts corrected or updated documents or offers another review.
- If appropriate, ask whether a different loan product could fit your circumstances. A lender may or may not offer another review or product, and these questions do not guarantee a change in outcome.
- If the decision may have involved the property’s value, request the appraisal or other written valuation and ask how to raise a specific concern.
Keep copies of the notice, your application documents, and any follow-up correspondence. Specific questions tied to a stated reason are more useful than a general request to “override the computer.”

Your right to an explanation does not depend on the technology
The CFPB’s Consumer Financial Protection Circular 2022-03 states: “The adverse action notice requirements of ECOA and Regulation B, however, apply equally to all credit decisions, regardless of the technology used to make them.” The CFPB says creditors must give specific, accurate principal reasons for adverse action. A complex algorithm does not excuse a vague explanation; citing internal standards or a qualifying-score failure alone does not substitute for specific reasons.
If the notice is unclear, ask the creditor to clarify the actual principal reasons for the decision. The CFPB’s ECOA examination procedures are useful context for how the Bureau examines underwriting practices, but they do not tell you which review route a particular lender must make available.

If the decision relied on your credit report
The CFPB’s consumer guidance, last reviewed December 31, 2024, says that when a lender denies an application based on a credit report, the notice should identify the numerical credit score used and key factors affecting it, name the reporting company and provide its contact information, explain the right to obtain a free report from that company within 60 days, and provide information about correcting errors or adding information. Check your notice and confirm current requirements if details are missing or unclear.
- Use the notice to identify which reporting company supplied the report and how to obtain it.
- Review the report for inaccurate or incomplete information relevant to the application.
- If you find an error, dispute it with the reporting company and with the company that supplied the information.
- Tell the lender if you have corrected or updated information, and ask whether it will consider it.
If the property valuation may have affected the decision
Regulation B includes provisions on appraisals and other written valuations. The CFPB’s ECOA valuation resources point to Regulation B § 1002.14 and its official interpretations. Request the appraisal or other written valuation, review it for specific factual errors, and ask the lender how to raise them.

Access to a valuation document does not guarantee a new appraisal, a particular appeal process, or reversal of the lending decision. The applicable process can depend on the lender, loan program, and other rules.

HUD-participating housing counseling agencies may offer credit counseling and pre-purchase or homebuyer education. Use HUD’s housing counseling agency search or phone line to find local options, and check which services are available: agencies do not all offer every type of counseling. HUD says counseling cannot be conditioned on using products or services offered by the agency, its affiliates, or community partners.

How to assess your next step
- Explanation: Does the notice state specific principal reasons?
- Accuracy: Could a credit-report item or application detail be wrong or incomplete?
- Valuation: Could the appraisal or another written valuation have affected the result, and have you reviewed it?
- Review availability: Has the lender confirmed whether it accepts corrected documents or offers another review?
- Independent support: Would credit or pre-purchase counseling help you plan, and is that service available from a HUD-participating agency near you?
Federal-rule context
The CFPB’s current Regulation B resource reports that the Bureau issued a final rule on April 22, 2026, amending provisions concerning disparate impact, discouragement, and special purpose credit programs. The Bureau says the rule removed the regulation’s “effects test,” modified the discouragement prohibition, and changed special-purpose-credit-program provisions. These changes do not establish a universal right to manual underwriting or reconsideration. For an individual case, check the current official regulation and the lender’s process; loan-program and state-specific procedures may also matter.
This is general information, not a determination of whether a particular lending decision complied with the law. If you believe a creditor did not provide an adequate explanation or handled your application improperly, consider seeking qualified legal or housing-counseling advice about your circumstances.
