FHA MIP and Underwriting Deep DiveWhat This Means for Your File
The Real MIP Math, Worked OutMortgage insurance premium runs on a fixed schedule set by HUD, not a sliding scale tied to credit score: 1.75% upfront, financed into the loan, plus an annual rate commonly 0.55% for a standard 30-year loan with less than 10% down. On a $400,000 purchase with 3.5% down, that works out to roughly $6,755 added upfront and about $177 a month in annual MIP. The exact rate ranges 0.15% to 0.75% depending on term, LTV, and loan amount.
Why Credit Score Doesn’t Move the NeedleA detail that surprises many borrowers: FHA mortgage insurance costs the same regardless of credit score, while conventional PMI pricing swings sharply with it. A borrower in the 580 to 620 range often pays less in FHA MIP than they would in conventional PMI, while a borrower above 720 usually finds conventional cheaper instead. The full comparison lives on the dedicated How Your Credit Score Affects Your Mortgage Rate page.
The Manual Underwriting DTI MatrixFHA manual underwriting applies a specific ratio matrix, not a single fixed ceiling: 31/43 with no documented compensating factors, climbing to 40/50 when 2 factors are properly documented in the underwriter’s file. Recognized compensating factors include verified cash reserves, minimal payment shock compared to current rent, and a clean 12-month on-time housing payment history. A credit score below 580 blocks this flexibility entirely, keeping the file capped at 31/43 regardless of how many factors are present.
Why Paying Extra Principal Doesn’t Remove MIPA detail that trips up many borrowers: paying down principal faster does not accelerate FHA MIP removal, unlike conventional PMI, which drops once you reach 80% LTV however you got there. HUD’s rule is explicit that early cancellation based on prepayment isn’t permitted, on files with less than 10% down. Refinancing into a conventional loan is the only realistic way to exit this cost early, regardless of how quickly the balance is paid down.

People Also AskWhy This Question Matters
How much does FHA mortgage insurance actually cost?Upfront MIP runs 1.75% of the loan amount, and annual MIP commonly runs 0.55%, adding roughly $177 a month on a $386,000 loan. This matters because the combined cost can shift the true monthly comparison between FHA and conventional financing.
Can I qualify for FHA with a DTI above 43%?Manual underwriting can approve up to 40/50 with 2 properly documented compensating factors. This matters because a borrower who assumes 43% is a hard ceiling may be overlooking a real path to approval. A credit score below 580 removes this flexibility entirely.
Does FHA mortgage insurance change based on credit score?No, FHA MIP stays flat regardless of credit score, unlike conventional PMI which scales sharply with it. This matters because a lower-credit borrower may find FHA meaningfully more competitive than conventional on the insurance cost alone. This gap can be worth hundreds a month.
