How to Buy a House in Arizona: A Complete 2026 Guide for First-Time Buyers
Every borrower situation is different, but Arizona first-time home buyers keep asking the same question: how little cash can I actually bring to closing? The answer usually comes down to stacking two specific numbers correctly, in the right order, rather than searching for one magic loan program that solves everything at once.
Key Takeaways
- FHA's 3.5% down payment can pair with Arizona's HOME Plus assistance for near-zero cash to close.
- HOME Plus requires a 620 FICO score and caps household income at $155,386 statewide.
- The current conforming loan limit is $832,750 across every Arizona county, with no high-cost exceptions.
- HOME Plus funds are a forgivable second lien, but selling or refinancing within 60 months triggers repayment.
- Closing costs run 2% to 5% of the purchase price on top of whatever down payment cash is needed.
How the Down Payment Math Actually Stacks Up
FHA loans and Arizona's down payment assistance work as one combined stack, not two separate topics to research on their own. The order you clear each layer determines whether you write a small check at closing or a much bigger one.
An FHA loan requires a minimum down payment of 3.5% for a credit score of 580 or higher; between 500 and 579, that minimum jumps to 10%. On a $350,000 home, 3.5% is $12,250, the number that scares off a lot of first-time buyers before they start.
Now stack the second layer. Arizona's HOME Plus program, run through the Arizona Industrial Development Authority, offers up to 4% of the loan amount toward down payment and closing costs. Layer that against the FHA requirement, and if you qualify for both, you can reach cash-to-close numbers close to zero, closing costs aside. That's the actual math when both pieces line up, but only if you clear the eligibility gates first.
Three Gates You Have to Clear, in Order
I've worked with buyers who assumed down payment assistance was something you apply for after finding a house. It's actually a qualification question you answer before touring a single property, and it comes down to three gates.
Gate one: credit score tier. FHA sets its floor at 580 for the 3.5% down payment. HOME Plus sets a higher floor: a minimum 620 FICO score. Sit between 580 and 619, and you can still get the FHA loan, but not the assistance layered on top. That 40-point gap is a common qualification surprise in this process.
Gate two: the income ceiling. HOME Plus caps borrower annual income at $155,386 statewide, one flat number rather than a sliding scale by county. Run your household income against that ceiling before you fall for a house that depends on the assistance being there.
Gate three: the education requirement. At least one borrower on your loan has to complete a HUD-approved home buyer education course before closing. Build it into your timeline early.
Your own file could land anywhere on that spectrum. If your score sits at 640 and your income is $140,000, you clear all three gates without a second thought. If your score sits at 600 with that same income, you clear gates two and three but never reach gate one, even though you still qualify for the base FHA loan. Knowing which situation you're in before you shop saves a disappointing surprise at underwriting.
The Forgiveness Clock You Need to Watch
There's a fourth thing to understand before signing anything: how the assistance works. HOME Plus is structured as a no-interest second lien behind your primary mortgage, fully forgiven after 60 months of on-time ownership.
That 60-month clock ties directly to how long you plan to stay in the home. Sell the home or refinance before the mark, and the assistance becomes repayable, since the forgiveness is contingent on staying put. If you're confident this is a five-plus-year home, you don't have much to worry about. If you suspect a job relocation, or want to refinance out of FHA mortgage insurance in year two or three, weigh that repayment risk first.
Sizing the Loan and the Rest of the Bill
Once the down payment stack is sorted, the next question is how much house that financing reaches. The baseline conforming loan limit for a one-unit property currently stands at $832,750, applied uniformly across every Arizona county, since none clears the high-cost threshold that raises the limit elsewhere.
Rates move independently of the down payment stack and matter just as much to the monthly number. The 30-year fixed rate recently averaged 6.69%, up slightly from the prior week, so check current rates before locking in old affordability assumptions. Arizona does offer one real offset: its average effective property tax rate on owner-occupied housing is 0.48%, well below the national average, worth weighing against principal and interest.
Closing costs are a separate line item that commonly gets underestimated even after the down payment math is settled: they typically run 2% to 5% of the purchase price, on top of the down payment itself. On that same $350,000 home, that's $7,000 to $17,500 more in cash needed at the table. Add that range to your down payment stack and you get the number that actually matters: total cash to close.
These numbers shift over time, and confirming them early keeps the closing table free of surprises. Ask about any gate, threshold, or cost line you don't understand while you're still shopping, so every figure is confirmed before you're under contract and nothing is left for a document to explain for the first time.

Frequently Asked Questions
Yes. The two are designed to work together as a single financing package. FHA requires a minimum 3.5% down payment for a credit score of 580 or higher, and HOME Plus can contribute up to 4% of the loan amount toward that down payment and closing costs. An AmeriSave loan officer can confirm whether both pieces apply to your file, since eligibility for the assistance layer depends on separate credit and income requirements.
You need a minimum 620 FICO score for HOME Plus, higher than the 580 minimum FHA sets for its own 3.5% down payment. If your score sits at 600, you can still get an FHA loan, but you won't qualify for the assistance on top, meaning the full 3.5% comes out of your pocket. This gap is a common qualification surprise for first-time home buyers.
Yes. HOME Plus caps borrower annual income at $155,386 statewide, applying the same way regardless of county. Above that figure, you'd still qualify for a standard FHA or conventional loan, just without the assistance layer.
Only under certain conditions. HOME Plus is a no-interest, deferred second lien fully forgiven after 60 months of ownership. Sell the home or refinance before that mark, and the remaining balance becomes repayable. If you're planning to stay long-term, you'll generally see it forgiven in full, while if your timeline is shorter, you should weigh that risk first.
The baseline conforming loan limit for a one-unit property currently stands at $832,750, applying to every Arizona county equally since none qualifies for a high-cost exception. That gives you one statewide ceiling for conventional financing before a purchase price requires jumbo loan terms. Your affordable price point also depends on your down payment, credit, and current mortgage rates.
Arizona's average effective property tax rate on owner-occupied housing is 0.48%, well below the national average. This lower recurring cost doesn't offset a higher purchase price directly, but it does reduce your total monthly payment compared to a similarly priced home in a higher-tax state. Factoring taxes into the full monthly payment gives a more accurate picture of what a home costs long-term.
Closing costs typically run 2% to 5% of the home's purchase price, separate from the down payment. On a $350,000 purchase, that range works out to roughly $7,000 to $17,500 in additional cash at the table. If you focus only on the down payment, you can easily underestimate your total cash-to-close. Getting a clear estimate early avoids a last-minute scramble for funds before closing.
