Direct Answer
An Arizona mortgage payment on a $425,000 Phoenix-area home with 10% down at 6.5% typically runs $2,900 to $3,050/month once property taxes, homeowners insurance, and private mortgage insurance (PMI) are included — not just the $2,417 principal-and-interest figure. Maricopa County’s effective property tax benchmark (roughly 0.61%) keeps monthly escrow moderate compared with Texas or Illinois, but school and special districts still change the bill by address.
Use the Arizona Mortgage Calculator or Maricopa County calculator — a mortgage calculator with taxes Arizona buyers search for — to estimate PITI (Principal, Interest, Taxes, and Insurance) with local tax data, PMI at your down payment level, and optional HOME Plus assistance.

Editorial note: This guide uses statewide planning estimates plus Maricopa County overrides for the Phoenix metro. Actual property tax bills depend on assessed value, exemptions, and local district levies. Insurance premiums vary by property, coverage, and ZIP code. This is educational content, not lending advice.
Research method: Daily Calcs modeled Arizona scenarios using configured state tax rates (0.63% statewide, 0.61% Maricopa override), median Arizona homeowners insurance estimates, standard 6.5% 30-year fixed amortization, and HOME Plus program data from official sources verified June 21, 2026.
Phoenix Monthly Payment Example: $425,000 Home
| Component | 10% Down ($382.5k loan) | 20% Down ($340k loan) |
|---|---|---|
| Principal & Interest (6.5%) | $2,417 | $2,149 |
| Property Tax (est.) | $216 | $216 |
| Homeowners Insurance | $190 | $190 |
| PMI (conventional) | $200 | $0 |
| Total PITI | $3,023 | $2,555 |
PMI estimate assumes 680+ credit score on a conventional loan. Property tax uses 0.61% Maricopa County benchmark on $425,000 market value.
The $468/month gap between 10% and 20% down is mostly PMI ($200) plus a lower loan amount. Reaching 20% down removes PMI and reduces principal and interest by $268/month.
Why Phoenix Property Tax Varies by Address
Arizona property taxes are local, not uniform statewide. A typical Maricopa County bill can include:
- county levy
- city levy (Phoenix, Mesa, Scottsdale, etc.)
- school district
- community college district
- special district
That is why a Phoenix mortgage calculator should use county- or city-specific data when possible:
How PMI and Down Payment Change Arizona Affordability
| Down Payment | Loan Amount | PMI/mo (est.) | PITI on $425k (est.) |
|---|---|---|---|
| 3% | $412,250 | $250 | $3,073 |
| 5% | $403,750 | $220 | $3,043 |
| 10% | $382,500 | $200 | $3,023 |
| 20% | $340,000 | $0 | $2,555 |
On a $130,000 salary, the 28% front-end debt-to-income (DTI) ratio cap is roughly $3,033/month for housing. That means 10% down on a $425,000 Phoenix-area home is near the affordability ceiling once PMI and insurance are included.
Arizona HOME Plus Down Payment Assistance
Arizona buyers may qualify for HOME Plus down payment assistance modeled as a percentage of the loan for eligible primary-residence buyers. Assistance lowers the loan amount, which directly reduces monthly PITI. It does not replace lender approval or program eligibility verification.
Calculator Methodology
The Arizona Mortgage Calculator uses:
Monthly P&I = P * r * (1 + r)^n / ((1 + r)^n - 1)- P = loan amount after down payment
- r = annual rate / 12
- n = term in months (360 for 30-year)
Property tax = effective local rate × home value / 12. Insurance and PMI are added separately. Maricopa County pages override the statewide tax benchmark for Phoenix metro buyers.
For the month-by-month principal and interest breakdown, use the loan amortization schedule — an amortization schedule with PMI shows how extra principal changes payoff time.

Frequently Asked Questions
What is included in an Arizona mortgage calculator with taxes and insurance?
A full Arizona mortgage calculator includes principal and interest (P&I), property taxes, homeowners insurance, and private mortgage insurance (PMI) when your down payment is below 20%. Together these form PITI (Principal, Interest, Taxes, and Insurance) — your total monthly housing payment. Arizona property taxes are set locally by county, city, school district, and special districts. The Daily Calcs Arizona calculator uses a statewide planning estimate plus Maricopa County overrides for the Phoenix metro.
How much are property taxes on a Phoenix or Arizona home in 2026?
Arizona effective property tax rates typically run 0.55% to 0.70% of assessed value depending on county and special districts. Maricopa County — which includes Phoenix, Mesa, Scottsdale, and Tempe — uses a metro benchmark near 0.61% in Daily Calcs data. On a $425,000 home, that translates to roughly $216 per month in escrow before city or special-district adjustments. Always verify the exact bill for the property address.
Does Arizona charge a statewide real estate transfer tax?
No statewide real estate transfer tax is modeled for Arizona in Daily Calcs data. Buyers should still budget for title, escrow, recording, and lender closing costs at settlement. That makes recurring monthly PITI the main comparison point for Arizona vs higher-tax states.
Does PMI apply on Arizona mortgages with less than 20% down?
Yes. Conventional loans with less than 20% down require PMI until you reach 80% loan-to-value (LTV). On a $425,000 Phoenix-area home with 10% down, PMI typically adds $190 to $240 per month depending on credit score and loan type. Federal Housing Administration (FHA) loans use mortgage insurance premium (MIP) instead of PMI. Arizona's relatively low property taxes mean insurance and PMI — not taxes — often drive the biggest payment swing between low and high down payments.
What Arizona down payment assistance programs exist in 2026?
The Arizona HOME Plus program models down payment assistance as a percentage of the loan for eligible primary-residence buyers, subject to income limits near $141,820 in configured scenarios. Assistance can reduce cash-to-close but does not replace lender underwriting — verify program availability, occupancy rules, and income caps before applying.
Phoenix vs Colorado mortgage payment: Which costs more per month?
On a $425,000 home with 10% down at 6.5%, Phoenix-area PITI runs roughly $2,980/month in this model while Colorado runs about $2,850 on a $400,000 home — similar bands driven by insurance and PMI more than property tax alone. Arizona's lack of a statewide transfer tax can lower cash-to-close compared with states that charge excise taxes at settlement. Use the Maricopa and Colorado calculators to compare your exact inputs.
