FHA Compensating Factors and DTI Guidelines
Quick answer: FHA manual underwriting is a file-by-file review under HUD Handbook 4000.1. The FHA baseline manual ratio matrix includes 31/43 for borrowers with a minimum decision credit score below 580 or no score, and several higher tiers for eligible borrowers at 580 or above when required compensating factors are documented. A ratio is a limit for a defined category, not a promise of approval.
This practical guide explains credit, housing history, collections, bankruptcy and foreclosure, income, assets, debt calculations, compensating factors, file documentation, and 20 common questions. Lender overlays may be stricter than FHA baseline rules.
Important policy-version note for 2026
HUD published Handbook Update 18 on August 12, 2026. The source guide supplied for this page states that lenders may implement its revisions early and must implement them no later than November 10, 2026. It also explains that its detailed rules use the November 26, 2025 handbook baseline and flag implementation differences where relevant. Because early adoption can change which handbook language a lender applies, ask the lender which effective version it is using for the FHA case number. Confirm every loan-specific rule in the current HUD Handbook 4000.1 and applicable mortgagee letters before relying on it. This page is an educational overview, not a substitute for the governing HUD text.
How FHA manual underwriting works
Manual underwriting means an underwriter evaluates the complete documented borrower and transaction instead of relying only on an automated recommendation. The review can include credit patterns, rental or mortgage payment history, income stability, assets and source of funds, monthly obligations, property eligibility, and the reasons an automated file was referred or downgraded. An FHA TOTAL Mortgage Scorecard result and a manual decision are different underwriting paths; neither is a blanket approval.
FHA manual underwriting DTI ratio matrix
Ratios below are shown as housing expense / total debt-to-income (DTI). “Minimum decision credit score” refers to the score used under applicable FHA rules. The underwriter calculates income and liabilities under the current effective handbook.
| Minimum decision credit score | Housing ratio | Total DTI | Baseline condition |
|---|---|---|---|
| 500–579 | 31% | 43% | Do not exceed these manual ratios under this matrix |
| No credit score | 31% | 43% | Subject to applicable manual and alternative-credit requirements |
| 580 or higher | 31% | 43% | No compensating factor required |
| 580 or higher | 37% | 47% | One acceptable, documented factor |
| 580 or higher | 40% | 40% | Special “no discretionary debt” exception |
| 580 or higher | 40% | 50% | Two acceptable, documented factors |
Do not treat the 40/40 tier as a general alternative to 37/47. Under the supplied guide, it requires no discretionary debt: the housing payment is the only open account with an outstanding balance not paid off monthly; established credit lines in the borrower’s name have been open at least six months and paid in full monthly for at least six months; authorized-user accounts do not meet that test. Energy-efficient homes may qualify for 33/45 stretch ratios where the applicable FHA provisions are met.
How the two DTI ratios are calculated
The housing ratio divides the proposed total monthly housing expense by gross effective monthly income. Housing expense may include principal and interest, property taxes, homeowners and flood insurance, FHA mortgage insurance, HOA or condominium fees, ground rent, special assessments, and applicable secondary-financing or escrow payments.
Total DTI divides the proposed housing expense plus applicable recurring monthly debts by gross effective monthly income. Debts can include auto, student, revolving and personal loans, child support, alimony, judgments under repayment, and other liabilities. FHA-specific rules determine which obligations count and how to calculate them; do not assume a deferred or business-paid debt is excluded.
Illustration only: With $7,000 gross monthly income, $2,450 proposed housing expense, and $1,050 other monthly debts, the housing ratio is 35% and total DTI is 50%. This would fit the numeric 40/50 ceiling only if the borrower has at least a 580 minimum decision credit score, two qualifying documented factors, and satisfies all other FHA and lender requirements. The example is not an approval.
Compensating factors: what they mean and when they count
Compensating factors are documented strengths that support a specified higher-ratio category. They do not replace acceptable credit, stable qualifying income, verified funds, or other eligibility requirements. The underwriter must explain why the factors apply to the borrower’s file; a borrower cannot simply select a factor or count one financial resource twice.
- Verified cash reserves: Eligible verified assets remaining after funds required to close and other applicable exclusions are accounted for.
- Minimal increase in housing payment: A documented comparison of established current housing expense with the proposed payment, evaluated in context.
- Residual income: A reasoned, documented look at income remaining after housing and recurring obligations, using an appropriate analysis. The guide’s arithmetic example illustrates the concept; it is not an FHA-prescribed calculation.
- Significant additional income: Certain documented income not already used as Effective Income. The supplied guide describes a history of at least one year, reasonable continuance, and enough income that including it in Effective Income would reduce the ratios to no more than 37/47.
| Manual ratio tier | Factor requirement in supplied guide |
|---|---|
| 31/43 | None |
| 37/47 | One: reserves, minimal housing-payment increase, or residual income |
| 40/40 | No discretionary debt under the specific test above |
| 40/50 | Two: reserves, minimal housing-payment increase, significant additional income, or residual income |
Credit score, credit history, and housing history
FHA baseline maximum financing is generally up to 96.5% LTV for a minimum decision credit score of 580 or higher, and up to 90% LTV for scores from 500 through 579. Scores below 500 are generally not eligible under the supplied guide. No-score borrowers are subject to applicable manual underwriting and alternative-credit requirements. These are FHA baselines, not guarantees; lender overlays, property rules, and complete-file review still apply.
The underwriter evaluates the overall pattern of financial responsibility, not only a score. Review can include revolving utilization, installment accounts, recent late payments, collections, charge-offs, inquiries, newly opened accounts, judgments, tax liens, prior bankruptcy, foreclosure, short sale, and mortgage or rental payment history. Housing history is especially relevant: the lender may verify recent rent or mortgage payments and assess whether the proposed payment is substantially higher.
A borrower without traditional credit may be able to establish nontraditional credit with independently verifiable recurring obligations such as rent, utilities, telephone, or insurance. FHA requirements govern the number, type, history, and verification. Lack of traditional credit alone cannot be the sole reason for denial. Compensating factors cannot be used to erase unacceptable derogatory-credit findings.
Collections, charge-offs, disputes, and judgments
For collections and charge-offs, the supplied guide says the underwriter evaluates whether the circumstances reflect disregard for obligations, inability to manage debt, or documented extenuating circumstances. Explanations should match the credit report and other file records. The underwriter documents the analysis; an account is not automatically resolved merely because it is old or charged off.
When outstanding collections shown in the credit analysis total $2,000 or more, the supplied guide describes three paths: verify payoff by settlement; document an established creditor payment arrangement and use its payment; or, if no arrangement is available, include a monthly amount equal to 5% of the outstanding balance of each collection account. Example: $2,700 aggregate balances with no arrangements produces $135 per month at 5%. Confirm the current effective handbook and how the lender applies the threshold to the specific file.
Disputed derogatory accounts need analysis and supporting records. The supplied guide notes limited exclusions such as documented identity theft or certain medical disputes. Court-ordered judgments generally must be resolved or paid at or before closing; a repayment exception described in the guide requires a valid agreement, three months of on-time scheduled payments, no priority over the FHA mortgage lien, and inclusion of payments in DTI. No advance-payment shortcut should be assumed.
Bankruptcy, foreclosure, deed-in-lieu, and short sale
The supplied reference summarizes common FHA waiting periods: generally two years after a Chapter 7 discharge, with a narrow documented-extenuating-circumstances path between 12 and 24 months; Chapter 13 may be considered after at least 12 months of on-time plan payments and written court permission; and foreclosure, deed-in-lieu, and short sale generally involve a three-year period, with specific exceptions. Event dates and exceptions depend on the applicable FHA provision. Divorce by itself is not identified as an extenuating circumstance in the supplied source. Verify timing and documentation under the current handbook before advising on a live file.
Income: stability, calculation, and continuance
Qualifying income must be verified, stable, reasonably expected to continue, and calculated under FHA rules. Common records include current pay statements, employment verification, W-2s, tax returns when applicable, and award or benefit letters. Variable pay such as overtime, bonus, commission, part-time, or seasonal income requires review of history, consistency, trend, and continuance; do not assume the highest recent amount qualifies. Declining earnings, employment gaps, job changes, and a move to commission income require careful analysis.
Self-employed files may require personal and business tax returns and schedules, year-to-date profit-and-loss statements, balance sheets, business verification, and evidence the business remains active. The underwriter evaluates income trends, expenses, ownership, cash flow, and stability. Social Security, disability, pension, annuity, child support, alimony, rental, investment, and other eligible income require the applicable verification, history, amount, and continuance evidence.
Assets, funds to close, gifts, deposits, and reserves
Funds for the required investment, closing costs, prepaids, and any required reserves must be eligible, available, verified, and sourced. Bank records may need all pages and may be reviewed for ending balances, large or unusual deposits, overdrafts, returned checks, cash deposits, and transfers. Keep a paper trail for transfers between accounts and explain material deposits with source records.
Gift funds may be acceptable from eligible donors when the donor, amount, source, gift terms, and transfer are documented under FHA requirements; a repayable loan must not be disguised as a gift. The supplied guide also calls for verification of earnest money when it exceeds 1% of sales price or appears excessive relative to the borrower’s savings history. Reserve calculations must use eligible verified assets and account for funds to close, gifts, borrowed funds, and cash received at closing as applicable.

20 FHA manual underwriting FAQs
1. What is FHA manual underwriting?
It is an underwriter’s documented review of the borrower, income, assets, credit, debts, housing history, and transaction under applicable FHA requirements, rather than relying only on an automated recommendation.
2. When might an FHA loan be manually underwritten?
A file may require manual review when it does not receive an acceptable FHA TOTAL Scorecard result or when applicable rules or the lender require a manual review or downgrade. Ask which underwriting path applies to the specific case.
3. What are FHA manual underwriting DTI limits?
The supplied 2026 guide’s matrix is 31/43 for scores 500–579 or no score; for 580+, 31/43 without a factor, 37/47 with one factor, 40/40 with no discretionary debt, or 40/50 with two factors. Apply the current handbook version and lender requirements.
4. Can FHA manual underwriting go to 50% DTI?
The supplied matrix includes 40/50 for eligible borrowers with a minimum decision credit score of 580 or higher and two acceptable documented compensating factors. The 50% figure is not an automatic approval threshold.
5. What is the FHA 40/40 ratio exception?
It is a special 40% housing / 40% total DTI category tied to the FHA “no discretionary debt” test. It is not a general substitute for 37/47, and authorized-user accounts do not satisfy the described established-credit-line test.
6. What compensating factors can FHA recognize?
The supplied guide identifies verified reserves, a minimal increase in housing payment, residual income, and certain significant additional income not counted as Effective Income. The applicable tier determines which factors and how many are needed.
7. How many factors are needed for 37/47?
One acceptable documented factor is required in the supplied matrix: reserves, minimal housing-payment increase, or residual income.
8. How many factors are needed for 40/50?
Two acceptable documented factors are required in the supplied matrix. The factors may include reserves, minimal housing-payment increase, significant additional income, and residual income, subject to current HUD requirements.
9. Can compensating factors offset bad credit?
No. They support specified DTI tiers; they do not replace acceptable credit analysis, erase derogatory credit, or override other eligibility requirements.
10. Can I qualify for FHA with a 500–579 score?
The supplied guide lists FHA baseline maximum financing up to 90% LTV and a manual ratio limit of 31/43 for that score band. Approval still depends on all applicable rules, lender overlays, and the complete file.
11. Can I get FHA manual underwriting with no credit score?
Possibly, under applicable FHA manual underwriting and alternative-credit requirements. Independently verified recurring obligations may help establish a nontraditional history; lack of traditional credit alone cannot be the sole reason for denial.
12. How are housing and total DTI calculated?
Housing ratio is the proposed full monthly housing expense divided by gross Effective Income. Total DTI adds applicable recurring debts to housing expense, then divides by gross Effective Income. FHA rules govern the exact amounts counted.
13. How are FHA collection accounts treated?
The underwriter evaluates the circumstances and documents the analysis. If outstanding collections total $2,000 or more, the supplied guide describes payoff, documented payment arrangements, or a 5%-of-balance monthly calculation for accounts without an arrangement. Verify current policy for the file.
14. Are charge-offs an automatic FHA denial?
The supplied guide says charge-offs are evaluated in context and are not automatically a denial. The borrower may need a consistent explanation and support, and the underwriter must document the credit analysis.
15. How are student loans treated in FHA DTI?
The applicable FHA student-loan payment calculation must be used. Do not assume the payment is excluded because the loan is deferred or a credit report shows no current payment; confirm the current handbook rule and supporting records.
16. What income documents may be needed?
Common records include pay statements, employment verification, W-2s, tax returns when applicable, and benefit or award statements. Self-employed and variable-income borrowers may need additional records to document history, stability, calculation, and continuance.
17. What is residual income as a compensating factor?
It is a documented analysis of income remaining after housing and recurring obligations, used to assess the borrower’s capacity. The lender must use an appropriate method; a simple online example is not an FHA-prescribed calculation.
18. Do large bank deposits matter?
They may. The lender may need to verify the source and show the funds are eligible and not undisclosed borrowed money. Keep supporting statements, transfer records, sale or gift documents, or other source evidence.
19. How long after bankruptcy or foreclosure can I apply?
The supplied guide summarizes general periods of two years after Chapter 7 discharge and three years for foreclosure, deed-in-lieu, or short sale, with limited exceptions; Chapter 13 has separate conditions. Dates, exceptions, and documentation must be checked against current HUD rules.
20. Does meeting an FHA ratio guarantee approval?
No. Ratios are only one part of underwriting. Credit, verified income and assets, liabilities, housing history, property, loan purpose, documentation, current HUD policy, and lender overlays all affect the decision.
