Which FICO Scoring Model Is Used for an FHA Home Loan?
SHORT ANSWER
HUD 4000.1 requires 3 specific classic FICO models for FHA loan underwriting — Equifax Beacon 5.0, Experian Fair Isaac Risk Model V2, and TransUnion FICO Risk Score Classic 04. The middle score among the 3 is the qualifying score, and if only 2 scores exist, the lower of the 2 is used rather than the middle. Smart Loan Savings Educational Content
| Target Element Name | Underwriting Impact on Your FHA Loan Profile |
|---|---|
| AUS Refer Finding | A computer cannot issue an approval on your FHA loan file when the qualifying score falls below the threshold the FHA TOTAL Mortgage Scorecard requires for the file’s specific conditions. A person then underwrites your file by hand for a closer look. What catches many borrowers off guard is that the qualifying score feeding the computer system is not a single bureau score or an average — it is the middle value of 3 separate bureau pulls, each generated by a different classic FICO model version. If only 2 of the 3 bureaus generate a score, the lower of those 2 is the qualifying score — not a middle value and not an average. A borrower with scores of 640 from Equifax and 610 from Experian, and no TransUnion score, qualifies at 610. That 30-point gap can determine which DTI ceiling and which down payment tier apply to the file. |
| The 3 Classic FICO Models — Why Each Bureau Is Different | The detail many borrowers miss is that Equifax Beacon 5.0, Experian Fair Isaac Risk Model V2, and TransUnion FICO Risk Score Classic 04 are 3 genuinely different mathematical formulas — not 3 versions of the same calculation. Each model was calibrated using that bureau’s own historical loan performance data, and each model weights the same credit behaviors differently. A borrower’s installment loan payment history carries different weight in Beacon 5.0 than it does in V2. A revolving account balance relative to its limit is scored differently in Classic 04 than in Beacon 5.0. This is why a borrower’s 3 classic FICO scores can differ by 20 to 30 points or more on the same day from the same underlying credit file — not because the data is different, but because the 3 models apply different weights to the same data. Confirming all 3 scores through a tri-merge pull before applying gives the only accurate picture of which qualifying score the computer system will use. |
| The Score Generation Threshold — What Creates a No-Score Result | Borrowers who assume every credit bureau will generate a classic FICO score are often surprised to learn that each classic FICO model requires at least 6 months of credit history and at least 1 account reported to that bureau within the last 6 months. A borrower who closed all active accounts 8 months ago may have a full credit history on file but generate no classic FICO score at all from that bureau — because no account was reported in the prior 6 months. A borrower with credit history at Equifax but no recent account reported to TransUnion may receive scores from 2 bureaus and nothing from the third. When only 1 bureau generates a score, that single score becomes the qualifying score with no middle-value calculation. Understanding which bureaus actually report the borrower’s accounts — before the tri-merge is pulled — can prevent a surprise no-score result at the submission stage. |
| The 12-Month Payment History Standard | HUD 4000.1 requires the DE underwriter on a manually underwritten FHA loan file to independently evaluate the most recent 12 months of payment history — not just accept the qualifying score. The 3 classic FICO models all weight recent payment history heavily, but the score they produce is a summary number. The underwriter reviews the underlying data directly. A borrower with a 590 qualifying score driven by 1 late payment 4 months ago presents a different underwriting picture than a borrower with a 590 qualifying score driven by an old collection from 4 years ago. Both borrowers produce the same qualifying score input for the computer system. The underwriter’s 12-month review of actual payment behavior is what differentiates the 2 files at the manual underwriting stage — and that review is independent of which of the 3 classic FICO models generated the qualifying number. |
| The Debt-to-Income Ratio | Lenders check if your monthly bills fit the standard debt rules used across FHA programs. The qualifying score produced by the classic FICO models directly sets which DTI ceiling a borrower can access. Scores of 580 and above unlock the compensating factor matrix up to 40/50. Scores below 580 are capped at 31/43 regardless of compensating factors. A borrower whose Equifax Beacon 5.0 score is 578 and whose Experian V2 score is 585 qualifies at the middle value under HUD 4000.1’s selection method. If all 3 scores are present, the middle score determines the DTI ceiling — not the highest score, not the average. In practice, a 7-point gap between 2 bureau scores can be the difference between the 31/43 ceiling and the 40/50 ceiling, and knowing which bureau is likely to return the middle score before applying is the information that lets a borrower plan their DTI position accurately. |

|---|---|
| What FICO score version does FHA use from each credit bureau? | HUD 4000.1 requires Equifax Beacon 5.0, Experian Fair Isaac Risk Model V2, and TransUnion FICO Risk Score Classic 04 for FHA loan underwriting. These are older, mortgage-specific formulas distinct from the FICO 8 or FICO 9 versions shown on most consumer credit apps. |
| Does FHA use my highest or middle FICO score for a home loan? | HUD 4000.1 uses the middle of the 3 bureau scores when all 3 exist. If only 2 bureaus generate a score, the lower of the 2 becomes the qualifying score, and a borrower with a 640 from one bureau and a 610 from another qualifies at 610 with no middle-value calculation. |
| Why are my 3 FICO scores different from each bureau on the same day for an FHA loan? | Equifax Beacon 5.0, Experian V2, and TransUnion Classic 04 are 3 different mathematical formulas that weight the same credit behaviors differently. A borrower’s installment loan history carries different weight in Beacon 5.0 than in V2, which is why scores from the same credit file can differ by 20 to 30 points across bureaus. |
