How Affordability Is Calculated

Lenders primarily look at your debt-to-income ratio (DTI) — your total monthly debt payments, including your new housing payment, divided by your gross monthly income. This calculator works backward from your target DTI to estimate a home price where your full monthly payment (principal, interest, taxes, insurance, and HOA) fits within that budget.

Arizona property tax rates are relatively low compared to many states, generally averaging around 1% of assessed value annually, though this varies by county and any local bond measures.

How to Use This Calculator

  • Max Back-End DTI — the percentage of your gross income lenders will allow toward all debts, including housing. Conventional loans often cap around 45-50%; FHA can be more flexible.
  • Planned Down Payment — affects both your loan amount and whether PMI applies, which factors into what price point keeps your payment on budget.

Frequently Asked Questions

How much house can I afford on my income in Arizona?

It depends on your income, existing debts, down payment, and current interest rates. This calculator gives a planning estimate; a full pre-approval considers your complete credit and asset picture for an exact figure.

What DTI ratio do lenders actually use?

Most conventional loans allow up to 45-50% back-end DTI with strong compensating factors like good credit or reserves. FHA loans can sometimes go higher. VA loans use a different residual income calculation alongside DTI.

Does this include Arizona down payment assistance programs?

Not directly. This calculator assumes your entered down payment percentage. If you're using a program like HOME+PLUS or Home in Five Advantage, your actual out-of-pocket cost could be lower. See our Arizona first-time buyer guide for details.
