The direct answer
FHA program guidelines allow a credit score as low as 580 with a 3.5% minimum down payment, and scores from 500 to 579 with at least 10% down. That is the floor HUD publishes — not the floor most Utah lenders actually approve. Because lenders add their own requirements on top of FHA guidelines, commonly called overlays, many Utah lenders set their working minimum somewhere in the low-to-mid 600s, and some require 620 or higher on every FHA file. The practical answer for a Utah buyer is that 580 keeps the 3.5% down payment available under FHA rules, 620+ opens the widest set of lenders and pricing, and scores below 580 usually require a larger down payment, a manual underwrite, or a period of credit repair first.
Verify current requirements in the HUD Single Family Housing Policy Handbook 4000.1 at hud.gov and with a Utah-licensed mortgage banker before making decisions — guideline minimums and lender overlays both change.
Two different numbers: FHA minimums vs. lender overlays
Almost every confusing answer you will read online comes from mixing up two separate things. The Federal Housing Administration insures the loan; it does not make the loan. HUD sets the outer boundary of what it will insure. The lender then decides, within that boundary, what it is willing to fund and service. A lender that must repurchase or service a delinquent loan carries real risk, so it sets a tighter internal standard.
| Credit score | FHA guideline | Typical Utah lender reality |
|---|---|---|
| 680 and above | 3.5% minimum down | Widest lender choice and best pricing; conventional financing often worth comparing. |
| 640–679 | 3.5% minimum down | Comfortably inside most Utah lenders' FHA overlays; down payment assistance generally available. |
| 620–639 | 3.5% minimum down | The most common lender overlay line. Approvable at many lenders; some assistance programs set their own 620 floor. |
| 580–619 | 3.5% minimum down | Allowed by FHA, but a shrinking pool of lenders. Expect stronger documentation, reserves, and compensating factors. |
| 500–579 | 10% minimum down | Rare in practice. Usually a manual underwrite with few participating lenders. |
| Below 500 | Not eligible | Not eligible for FHA insurance. Focus on credit rebuilding first. |
This is why two Utah buyers with identical scores can get opposite answers on the same day. They did not hit different FHA rules — they hit different lenders.
Which score the lender actually uses
Mortgage lenders do not use the score shown in a free credit app. They pull a tri-merge report with a score from each of the three bureaus and use the middle score. On a joint application, the lower of the two borrowers' middle scores usually governs. Mortgage scoring models are also generally older and stricter than the consumer-facing models used by card issuers and budgeting apps, so it is normal for the qualifying score to come in lower than the number on your phone.
Example: how the middle score is chosen
A Utah buyer pulls 611, 628, and 646. The qualifying score is 628 — not the highest, not the average. If a co-borrower's middle score is 604, the file is generally underwritten at 604.
What underwriting reviews besides the score
The score is a summary, not the decision. FHA underwriting weighs the whole file, and a strong file can carry a modest score.
- Payment history: recent housing-payment lates matter far more than an old collection.
- Debt-to-income ratio: total monthly obligations against gross income, including student loans that are deferred.
- Documented, stable income: two years of history is the standard framework, with reasonable explanations for gaps.
- Verified funds: sourced and seasoned down payment, closing costs, and reserves.
- Derogatory events: bankruptcy, foreclosure, and short-sale seasoning periods with documented circumstances.
- Compensating factors: reserves, a low payment shock, a long employment history, or minimal other debt.
Automated approval vs. manual underwriting
Most FHA files run through an automated underwriting system. When the system does not return an approval — often because of a thin file, a low score, or a higher debt ratio — the loan may still be eligible through manual underwriting, where a human underwriter reviews the full picture against tighter ratio limits and documented compensating factors. Manual underwrites take longer and require more paperwork, and not every Utah lender offers them. Ask early whether the lender you are talking to does manual FHA underwriting at all.
Utah-specific considerations
Along the Wasatch Front, FHA is heavily used by first-time buyers because of the 3.5% down payment and its flexibility with gift funds. Three Utah realities are worth planning around.
- Down payment assistance sets its own floor. Utah Housing Corporation and other assistance programs publish their own credit-score minimums, which are frequently higher than FHA's. If you are pairing FHA with assistance, the program's floor is the one that governs. See Utah Housing Corporation programs and resources.
- Competitive offers reward certainty. In fast Utah submarkets, a fully underwritten pre-approval reads as stronger than a quick prequalification, especially at lower scores.
- Condo and townhome projects add a second approval. An FHA condo purchase depends on project eligibility in addition to your score.
How to move your score before you apply
- Pull all three reports free at AnnualCreditReport.com and read them line by line.
- Dispute genuine inaccuracies in writing with the bureau and the furnisher.
- Pay revolving balances down well below their limits before the statement date, not after.
- Keep every payment current — recent lates carry the most weight.
- Leave old accounts open; closing them shortens history and raises utilization.
- Stop opening new accounts and avoid financing a car during the process.
- Do not pay a collection without first asking your loan officer how it will be treated.

When a higher score means you should compare conventional
FHA mortgage insurance is priced largely independent of credit score, while conventional private mortgage insurance is priced heavily by score. That creates a crossover: at lower scores FHA is usually the cheaper monthly payment, and as the score climbs into the 700s a low-down-payment conventional loan often becomes cheaper, with the added advantage that PMI can be removed later while FHA's annual mortgage insurance premium generally stays for the life of most loans originated with the minimum down payment. Always compare a real Loan Estimate for both, not a rule of thumb. Details live in The Complete Utah FHA Loan Guide.
