FHA vs Conventional in Arizona — which actually wins?
The honest answer depends on your credit score, how long you'll stay in the home, and whether you can refinance later. Here's the math, in plain English.
Quick answer
- Credit 580–679: FHA is usually the only path or the cheapest one.
- Credit 680–739: Conventional often wins long-term because mortgage insurance drops off automatically.
- Credit 740+: Conventional almost always wins. Best pricing tier on the market.
- Planning to refinance or move within 3 years: FHA can still make sense even with strong credit because of the upfront access.
Side-by-side comparison
| Feature | FHA | Conventional |
|---|---|---|
| Minimum credit score | 580 (3.5% down) or 500 (10% down at some lenders) | 620 (660+ for best pricing) |
| Down payment | 3.5% | 3% (first-time buyer programs) or 5% |
| Mortgage insurance | For the life of the loan (unless 10%+ down) | Drops off automatically at 78% loan-to-value |
| Upfront fee | 1.75% of loan added to balance | None |
| Loan limits in Arizona | Lower than Conventional | Up to standard conforming loan limit |
| Property condition | Stricter inspection standards | More flexible |
| Best for | Lower credit, lower savings, first home with plan to refinance | Stronger credit, longer hold, long-term cost optimization |
When FHA actually wins
- Your credit is between 580 and 679 — Conventional pricing gets expensive in this range, FHA stays competitive.
- You have legitimate credit blemishes within the last 2–3 years — FHA is more forgiving on past credit events.
- You plan to refinance to Conventional once you build equity — common play in Arizona's appreciating markets.
- The home needs FHA-compliant condition standards — sometimes a feature, not a bug.
When Conventional actually wins
- Your credit is 680+ — pricing tiers reward stronger credit.
- You'll stay in the home 5+ years — the no-mortgage-insurance period after you hit 78% loan-to-value adds up.
- You're putting 20% or more down — no mortgage insurance from day one.
- You're targeting a home above the FHA loan limit in your county.
A real Arizona scenario
Compare a $350,000 Phoenix home with a 680 FICO, putting 3.5% down on FHA versus 3% down on Conventional. The FHA payment may start lower due to looser underwriting and similar rate pricing — but the conventional borrower's mortgage insurance drops off automatically once they reach 78% loan-to-value. Over a 7-year hold, the conventional path often saves $5,000–$15,000 in total cost. Over 3 years, the math is much closer.

Frequently asked questions
What credit score do I need for FHA vs Conventional in Arizona?
FHA needs a 580 credit score for the 3.5% down option, or 500 to 579 if you put 10% down. Conventional loans like the Conventional 97, Fannie Mae HomeReady, and Freddie Mac Home Possible need a 620 minimum. Between 580 and 679, FHA is usually the cheaper path; at 680 and up, Conventional pricing tiers start to win. We pull your scenario and compare both.
How much down payment does each loan require?
FHA requires 3.5% down with a 580 score (10% down if your score is 500 to 579). Conventional first-time buyer programs go as low as 3% down with a 620 score. On a $350,000 Phoenix home, that is $12,250 down on FHA versus $10,500 on Conventional 97. The smaller gap means down payment alone rarely decides it; mortgage insurance and credit usually do.
How is mortgage insurance different between FHA and Conventional?
FHA charges a 1.75% upfront mortgage insurance fee added to your loan balance, plus monthly mortgage insurance that stays for the life of most loans (unless you put 10% or more down). Conventional mortgage insurance has no upfront fee and drops off automatically once you reach 78% loan-to-value. Over a 5-to-7-year hold, that automatic drop-off is why Conventional often wins on total cost.
What are the 2026 Arizona loan limits for FHA and Conventional?
The 2026 FHA loan limit in Maricopa County is $557,750, while the Conventional conforming limit is $832,750. If your target home pushes past the FHA cap, Conventional is often the only option that keeps you in standard financing. For most first-time Phoenix homes under the FHA limit, both loans are on the table and the choice comes down to credit and how long you will stay.
Can I use down payment assistance with both FHA and Conventional?
Yes. Arizona's main programs pair with both loan types: Home Plus is statewide with up to 5% assistance (4% plus 1% for Active Duty and Veterans) and requires a 620 FICO, and Home in Five in Maricopa County offers up to 6.5% and requires a 640 FICO. Assistance programs do not stack with each other, so you pick one per purchase. We model which program plus loan combination costs you the least.
Should I look at VA or USDA before FHA vs Conventional?
Yes, check those first. If you are a Veteran or eligible service member, a VA loan usually beats both FHA and Conventional with $0 down and no monthly mortgage insurance. In USDA-eligible areas (most of Maricopa County is excluded), a USDA loan offers $0 down within income limits. The usual order is VA first, then USDA, then FHA vs Conventional.
Can I switch from FHA to Conventional later?
Yes, and many Arizona buyers do. Once you build enough equity, typically 20% through paydown or appreciation, refinancing to Conventional drops the FHA mortgage insurance and can lower your monthly payment. This is a common play in Phoenix's appreciating markets, where buyers start with FHA's looser 580-credit qualifying and refinance out of the lifetime mortgage insurance within a few years. We help clients plan this from day one.
