Does the FHA Home Loan Program Use Different Credit Score Tiers?

SHORT ANSWER Yes. The FHA home loan program uses 3 credit score tiers under HUD 4000.1, with 3.5% down at 580 or higher, 10% down from 500 to 579, and no eligibility for scores below 500. Each tier also sets the maximum LTV at 96.5% or 90%, and files from 500 to 579 are often manually underwritten with the DTI capped at 31/43 on that path. Smart Loan Savings Educational Content

AUS Refer FindingA computer cannot issue an approval on your FHA home loan file. A person then underwrites your file by hand for a closer look. Tier 1 borrowers (580 and above) may receive an Accept from TOTAL and proceed with back-end DTI flexibility up to 56.9%. Tier 2 borrowers (500 to 579) rarely receive an Accept, and lender program rules route nearly all of these files to manual underwriting with a 31/43 DTI cap. For example, what borrowers often learn on the call is that dropping from 580 to 579 often closes the AUS path in practice and cuts the back-end ceiling from a potential 56.9% to a hard 43%, which can change whether the file qualifies at all.
The 4 Consequences of Each Tier — Not Just the Down PaymentEvery competing site presents the FHA tiers as a 2-column down payment table. The tier boundary actually moves 4 variables at once: down payment (3.5% versus 10%), maximum LTV (96.5% versus 90%), the underwriting path in practice, and the DTI ceiling (up to 56.9% on the Tier 1 AUS path versus a 31/43 cap on manually underwritten Tier 2 files). The first 2 are HUD 4000.1 tier rules, and the second 2 follow from how each tier plays out in underwriting. For example, what borrowers often learn on the call is that a borrower at 578 faces 4 simultaneous changes versus a borrower at 580, and moving 2 score points unlocks all 4 at once.
The Dollar Value of 1 Score Point at the 579-to-580 BoundaryOn a $300,000 purchase the difference between a 579 and a 580 score is $19,500 in required down payment — $30,000 at 10% versus $10,500 at 3.5%. The same 6.5% gap applies at any price: $16,250 at $250,000 and $22,750 at $350,000. The boundary applies to the Minimum Decision Credit Score — the middle score of the 3-bureau pull, or the lower of 2 scores. For example, what borrowers often learn on the call is that before accepting 10% down, they should ask the lender whether a rapid rescore on 1 bureau could move the middle score to 580, because moving 1 point saves $19,500 on a $300,000 purchase.
The 12-Month Housing History Across TiersA documented 12-month on-time housing history is a compensating factor on Tier 1 files and a required documentation element on manually underwritten Tier 2 files. Acceptable documentation is a formal VOR from a management company, 12 months of cancelled checks, or 12 months of bank statements showing rent transfers — cash payments are excluded regardless of tier. For example, what borrowers often learn on the call is that a Tier 2 borrower paying cash rent faces 3 constraints at once: higher down payment, lower DTI ceiling, and no documentable housing history, which makes reaching Tier 1 even more valuable before applying.
The Debt-to-Income RatioLenders check if your monthly bills fit the standard debt rules used across FHA programs. Tier 1 borrowers on the AUS path may qualify up to 56.9% back-end, and Tier 1 manual files use the 31/43 baseline with 37/47 and 40/50 tiers available through compensating factors. Tier 2 files follow the manual path at nearly all lenders, and compensating factors cannot move the 31/43 cap there. On $5,000 gross monthly income, the Tier 1 AUS ceiling allows $2,845 in monthly obligations and the Tier 2 cap allows $2,150. For example, what borrowers often learn on the call is that this $695 monthly gap is often the specific difference that determines whether a borrower qualifies at their target purchase price.
