What Credit Score Do You Need to Buy a House in Arizona? By Loan Type and Assistance Program
Short answer: You can buy a house in Arizona with a credit score as low as 580 on an FHA loan with 3.5% down, 620 on a conventional loan, and no set minimum on a VA loan, though most lenders want 620. Arizona's down payment assistance programs, Home Plus and Home in Five, require a 620 to 640 minimum depending on the program and loan type. A score of 680 or higher opens up better rates and lower mortgage insurance.
Credit score is the first thing a lender checks and the first thing buyers ask me about. Here is what each loan type and assistance program requires in Arizona, and what to do if you are close but not there yet.
Minimum credit score by loan type and program
| Loan or program | Minimum score | Down payment | Notes |
|---|---|---|---|
| FHA | 580 (500 to 579 with 10% down) | 3.5% | Most Arizona lenders set their own floor at 600 to 620 |
| Conventional (Fannie Mae, Freddie Mac) | 620 | 3% to 5% | Rates and mortgage insurance improve sharply above 680 and 740 |
| VA | No program minimum | 0% | Lenders commonly require 580 to 620 |
| USDA | No program minimum | 0% | 640 for automated approval; rural areas only, which excludes most of the West Valley |
| Arizona Home Plus | 620 to 640 | Assistance covers up to 5% of the loan | Statewide; income cap about $155,000 in 2026; minimum varies by loan type |
| Home in Five Advantage | 640 | Assistance up to 7% | Maricopa County only |
| Jumbo (over conforming limit) | 700 to 720 | 10% to 20% | Relevant for north Peoria and luxury purchases |
What your score actually changes
- Approval. Below the minimum, the loan is not available at all.
- Interest rate. On a conventional loan the gap between a 640 and a 760 score can be half a percentage point or more, which is roughly $150 a month on a $400,000 loan.
- Mortgage insurance. Conventional private mortgage insurance is priced by score. FHA mortgage insurance is the same regardless of score, which is why FHA often wins for buyers under 680.
- Assistance eligibility. Home Plus and Home in Five have hard floors. A 630 score can mean the difference between $20,000 of assistance and none.
If you are close but not there
- Pull all three reports and dispute errors. Lenders use the middle of three scores, so a single bad report drags you down.
- Pay credit cards below 30% of their limits before the lender pulls credit. Utilization is the fastest lever.
- Do not close old accounts or open new ones in the months before applying.
- Ask the lender for a rapid rescore after paying balances down. It can update scores in days instead of a month.
- Consider FHA if you are between 580 and 640. You can refinance into a conventional loan later when your score improves.
