The short answer
Manual underwriting is a mortgage assessment under a program’s written manual rules rather than an automated approval. It can help eligible borrowers with an automated referral or limited traditional credit, but it does not remove debt, credit, or documentation requirements. First establish whether your loan is eligible for that route and whether the lender offers it.
A human review and manual underwriting are different things
People are involved in automated mortgages too. The lender checks the information, verifies the documents, and remains responsible for the loan. Manual underwriting changes the method of assessing risk and the requirements that apply.
A second opinion might correct an automated file, evaluate another program, or identify a permitted manual route. It should select the appropriate method rather than assume “manual” is always better.
Two assessment routes. A lender in both.
Automated route
- Application data enters the system
- The system returns findings
- The lender verifies the file and requirements
Manual route
- The lender establishes manual eligibility
- An underwriter applies the manual rules
- The lender verifies the file and requirements

When manual underwriting deserves a closer look
Start with the reason the automated or traditional-credit route did not work. These are different entry points, not interchangeable approvals.
| Situation | What must be established |
|---|---|
| FHA TOTAL returns Refer | The file needs an FHA Direct Endorsement underwriter’s assessment under applicable requirements. |
| A conventional DU result is unfavorable | Whether that transaction permits manual underwriting and meets its separate requirements. |
| No credit score or limited traditional credit | Whether an eligible nontraditional-credit or automated cash-flow route applies. |

What an FHA Refer result actually means
HUD’s TOTAL scorecard returns a risk assessment through an automated system. “Refer” directs the file to an FHA Direct Endorsement underwriter; HUD states that the mortgage cannot be approved or denied solely on the TOTAL result.
If you were told only that the computer rejected your FHA loan, ask whether the lender evaluated the required manual route and which requirement the loan failed. A referral creates a review step, not a guarantee that the application meets FHA rules.

No credit score does not mean no payment history
The lender needs acceptable evidence of how you handle recurring obligations. For a Fannie Mae manually underwritten loan using nontraditional credit, requirements include a one-unit principal residence, an eligible purchase or limited cash-out refinance, and a maximum 36% DTI. Other credit-reference and reserve conditions apply.
Confirm that the lender first checked whether your credit report is accurate. A missing score caused by incorrect identifying information is a reporting problem. A low existing score is also different from having no score; the nontraditional route generally cannot be used to discard an unfavorable credit record.
Manual review is not a workaround for every denial
Manual rules can be tighter. For Fannie Mae loans, the general manual DTI limit is 36%, potentially up to 45% with the specified credit and reserve criteria; DU allows up to 50%, subject to the rest of the file. Special transactions can have lower limits.
A high-DTI borrower should therefore check the applicable route before asking to switch to manual underwriting. Nor does self-employment automatically require a manual loan: documenting income correctly can be part of an automated application.

The document list should follow the program and the problem. Ask what each extra record must establish and what period it needs to cover.
Evidence by issue
- Limited credit
- The payment references and history the lender accepts under the selected program.
- Income
- Returns, pay records, or business records supporting the amount and continuity of earnings.
- Cash
- Statements tracing funds for down payment, closing, and any required reserves.
- Past disruption
- An accurate explanation and supporting documents, plus evidence of the current payment position.
A personal explanation does not replace the required evidence. Keep the original finding and denial explanation with the records so the new reviewer knows why the route is being considered.

How to find a lender that will take the case
Ask whether it accepts manual submissions for your program and your particular issue. Advertising FHA or conventional loans does not establish that a lender handles every manual scenario.
Get a document list and an estimate based on the work remaining. There is no useful universal promise that manual underwriting adds exactly a certain number of days. Ask about underwriting availability, property review, and the purchase deadline.
If a lender can proceed, compare the loan terms as well as the method. A manual assessment describes how the file is evaluated; it does not by itself tell you the rate or fees.
