Manual underwriting is when a human underwriter approves or declines your loan by applying the program's written rules directly, instead of relying on an automated "Accept" or "Approve." It usually happens because the automated system returned a Refer, or because something in the file forces a downgrade, like a recent bankruptcy or derogatory accounts the system can't evaluate. It isn't a denial and it isn't a loophole. It's a stricter, more documented path through the same program, and on FHA it comes with hard ratio limits and a specific list of compensating factors. I do offer FHA manual underwriting, at our 580 minimum score, so a Refer doesn't automatically end the conversation.
How automated and manual underwriting fit together
Most files today start in an automated underwriting system. It reads the application, the credit report and the assets and returns findings. The names differ by program:
- FHA: TOTAL Mortgage Scorecard, run through Fannie's or Freddie's system, returns Accept or Refer.
- Conventional: Fannie Mae's Desktop Underwriter (DU) returns Approve/Eligible, Refer, or Ineligible. Freddie Mac's Loan Product Advisor (LPA) returns Accept or Caution.
- VA: VA files run through DU or LPA, and a Refer goes to a manual decision under VA's rules.
- USDA: the Guaranteed Underwriting System (GUS) returns Accept, Refer, or Refer with Caution.
An automated approval doesn't mean nobody looks at your file. The underwriter still has to verify that everything entered is accurate and complete. The difference on a manual file is that the underwriter is the decision, not just the checker. For a plain-English walkthrough of the findings themselves, see automated underwriting findings.
Why an FHA file goes manual
HUD says the underwriter must manually underwrite any file where TOTAL returns a Refer, or any result other than Accept (HUD 4000.1 II.A.4.a.iv(C)). HUD also requires a downgrade to manual even after an Accept when, among other things (HUD 4000.1 II.A.4.a.v):
- The file has information TOTAL can't enter or evaluate, or new information that affects whether the loan can be insured.
- You have $1,000 or more in disputed derogatory accounts.
- Your bankruptcy discharge is within two years of the FHA case number date.
- A foreclosure, deed-in-lieu, or short sale transferred title within three years of the case number date.
- Your mortgage payment history or undisclosed mortgage debt requires it.
- Business income declined more than 20 percent over the analysis period.
Once a file is downgraded, the lender stops using the automated findings and follows every manual requirement. You can't "rescore your way back" to an Accept by leaving facts out.
The FHA manual rules, layer by layer
Credit history
On a manual FHA file, the underwriter looks at your pattern of credit, starting with housing payments, then installment debts, then revolving accounts. HUD treats credit as acceptable when all housing and installment payments were on time for the last 12 months, with no more than two 30-day lates on mortgage or installment debts in the last 24 months, and no major derogatory revolving credit in the last 12 months. If your history doesn't meet that, the underwriter can approve only after documenting that the late payments came from extenuating circumstances (HUD 4000.1 II.A.5.a.iii(B)). Your last 12 months of rent or mortgage payments have to be verified, through the credit report, the landlord or servicer, or canceled checks (II.A.5.a.iii(C)). One more rule people miss: HUD says compensating factors can't be used to make up for derogatory credit (II.A.5.d.iii). They help with ratios, not with late payments. If collections are part of your story, see collections and charge-offs.
Debt-to-income limits
HUD's manual ratio matrix uses two ratios: your total housing payment to income, and your total monthly debts to income (HUD 4000.1 II.A.5.d.viii):
- 31/43 with no compensating factors needed (33/45 for a home that qualifies as energy efficient).
- 37/47 with one compensating factor: verified cash reserves, a minimal increase in housing payment, or residual income.
- 40/40 with no discretionary debt.
- 40/50 with two compensating factors.
- Scores from 500 to 579, or no credit score, are capped at 31/43 under HUD's matrix.
The stretch bands above 31/43 are for scores of 580 and above. Since our FHA minimum is 580, those are the bands that apply to files I take. For the bigger picture on ratios, see debt-to-income.
Compensating factors, as HUD defines them
A compensating factor isn't a good story. It's a specific, documented strength HUD lists (HUD 4000.1 II.A.5.d.ix):
- Verified cash reserves: at least three total monthly mortgage payments after closing on a one or two unit home, or six on three to four units. Gifts, borrowed money and cash-out proceeds don't count toward it.
- Minimal increase in housing payment: the new payment isn't more than $100 or 5 percent higher than what you pay now, whichever is less, with a documented 12-month housing history with no more than one 30-day late. If you have no current housing payment, this factor isn't available.
- No discretionary debt: your housing payment is your only open account carrying a balance, you have credit lines in your name open at least six months, and you can show they've been paid in full monthly for at least six months. Authorized-user accounts don't count.
- Significant additional income not used to qualify: overtime, bonus, part-time or seasonal income received for at least a year and likely to continue, enough to bring ratios to 37/47 or below. It only counts alongside another factor.
- Residual income: what's left each month after taxes, debts and estimated maintenance and utilities, measured against VA's residual income table for your family size and region.
Reserves
Separate from the compensating factor, every manual FHA file needs some reserves after closing: one month's total payment on a one or two unit home and three months on three to four units (HUD 4000.1 II.A.5.c.i(C)). See reserves for what counts.
No credit score
HUD's handbook has a path for borrowers without a score: either a nontraditional mortgage credit report or a credit history the lender builds by hand, with three references that include rent, phone, or a utility when available, each backed by 12 months of proof (HUD 4000.1 II.A.5.a.ii(B)). HUD also says a lack of traditional credit can't be the only reason for a denial. Whether a no-score FHA file fits with us depends on your situation, so ask me how this applies to your file before you plan around it.
A note on dates: the version of HUD's Handbook 4000.1 lenders follow today is Update 17, issued November 26, 2025. HUD issued Update 18 on August 12, 2026, and lenders must use it by November 10, 2026. The ratio matrix and compensating factors described above are long-standing FHA rules and read the same in both versions.
Manual underwriting on other loan types
- Conventional (Fannie Mae). Manually underwritten loans are held to Fannie's Eligibility Matrix, which sets minimum scores and reserves by loan-to-value, units and debt ratio. Scores start at 620 in the most favorable cells and go up from there, and the debt ratio is 36 percent, or up to 45 percent when the matrix's score and reserve requirements are met (Selling Guide B3-6-02; Eligibility Matrix, Aug 5, 2026). A DU Refer doesn't automatically mean a manual conventional loan is possible, and many lenders don't manually underwrite conventional at all. Ask me how this applies to your file.
- VA. VA uses two tests, debt-to-income and residual income. Above a 41 percent ratio, the loan can still be approved with a supervisor's written justification, and that extra review isn't required when residual income beats VA's guideline by at least 20 percent (38 CFR 36.4340(c)). VA itself sets no minimum credit score (VA Loan Guaranty credit underwriting training, 2023).
- USDA. USDA's regulation sets repayment ratios of 29 percent for housing and 41 percent total, and allows higher ratios with compensating factors. When GUS downgrades a file to manual, the lender has to document those factors (7 CFR 3555.151(h)).
Agency rule vs. lender overlay
Everything above is the agency's rule. A lender can add its own stricter rules on top, called overlays, like a higher score for manual files or a lower ratio cap. That's why two lenders can give different answers on the same manual file. On FHA, our only overlay is the 580 minimum score. Beyond that, I follow HUD's handbook. Texas down payment assistance programs can add their own requirements on manual files too: TSAHC, for example, asks for a 640 score and a 43 percent ratio on manually underwritten FHA loans (TSAHC homebuyer programs).
Fictional example
This example is made up to show how the layers work.
Marisol in Arlington has a 604 middle score and a steady job, but two 30-day late car payments in the last year, so TOTAL returns a Refer. Her file goes manual. The underwriter reviews her housing and installment history, asks for a letter and proof that the late payments came from a two-month hospital stay, and verifies 12 months of rent with her property manager. Her ratios come in at 36/45, above the 31/43 base, so she needs one compensating factor. Her new housing payment would be a big jump over her rent, so "minimal increase" doesn't work, but she has more than three months of payments in savings after closing that aren't a gift. That's a documented reserves factor, which supports the 37/47 band. The underwriter still decides whether the late payments are explained well enough.
Common mistakes and myths
- "Refer means denied." No. On FHA, a Refer means a person has to underwrite the file by hand.
- "Manual means looser." It's usually stricter. The ratio caps are lower than many automated approvals, and the documentation list is longer.
- "A strong letter is a compensating factor." Only the factors HUD lists count, and each has to be documented.
- "Compensating factors fix late payments." HUD says they can't offset derogatory credit.
- "Gift money counts as reserves." Not for HUD's reserves factor.
- "Every lender does manual FHA." Many don't, or they add overlays. Ask before you assume.
What to have ready
- Twelve months of rent or mortgage history: canceled checks, bank statements showing the payments, or your landlord or property manager's contact for verification.
- Complete statements for every account, all pages, so reserves can be counted.
- Letters of explanation with dates and proof for any late payments, collections, or credit events.
- Paperwork for any bankruptcy, foreclosure, or short sale, including discharge or sale dates.
- Your usual income documents, plus a year of history for any overtime, bonus or part-time income.
- Extra time on the contract. Manual files take longer, so don't promise a quick close at the offer table.
