What is the maximum DTI for an FHA loan?
FHA does not have one simple DTI number that applies to every file. Automated approvals can allow higher DTIs (FHA's published ceiling is around 56.99% back-end with strong compensating factors), but lender overlays often cap lower — 50% is common, 55% is the practical ceiling for many channels. Manual underwriting is stricter. The real answer depends on credit, reserves, income stability, compensating factors, and automated underwriting findings.
What this actually means.
DTI is your total monthly debts divided by your gross monthly income. FHA looks at two ratios: front-end (housing payment alone vs income) and back-end (housing plus all other monthly debts vs income). Common front-end guideposts cluster around 31–40%; common back-end clusters around 43–50% with overlays, but FHA's automated approvals have cleared back-end DTIs past 55% when reserves, credit, and the rest of the file are strong. Manual underwriting tightens DTI caps materially. Subject to FHA/HUD guidelines and lender overlays. The real answer for your file comes from running it with a lender, not a one-size DTI rule.
What this looks like on a real file.
Where this can move.
Income type and history, recurring debts shown on the credit report, automated vs manual underwriting, compensating factors, and lender overlays can change the answer.
