California vs Arizona: mortgage & affordability comparison
Side-by-side: median home price, effective property tax, monthly PITI on the median home, and the income required to afford it under the 28% front-end DTI rule. Adjust the rate and down payment to model your own scenario.
| Metric | California | Arizona |
|---|---|---|
| Median home price | $770,000 | $430,000 |
| Property tax rate | 1.25% | 0.63% |
| Monthly principal & interest | $4,541 | $2,536 |

| Monthly PMI | $462 | $258 |
| Monthly PITI total | $5,925 | $3,140 |

Which state is more affordable, really?
On paper, Arizona comes out ahead at the median-home level — about $2,785/month less in PITI on a typical home with 10% down at today's rates. Multiply by 360 payments and the lifetime difference runs into the $1,002,600 range — before refinances or moves.
But "affordable" is two numbers, not one. The income ratio matters just as much as the dollar amount. California's median household earns $91,000 vs Arizona at $73,000; against each state's median home, you'd need $253,930 in California and $134,554 in Arizona to qualify under the standard 28% rule. The smaller the gap between "needed" and "median," the less stretched the typical buyer is.
Property tax is the most under-appreciated driver. California bills 1.25% per year vs Arizona's 0.63% — that single line adds or removes $576/month on the median home, more than most rate moves of 0.25%.
Beyond the mortgage
This page compares the housing math only — the part lenders look at. State income tax, sales tax, insurance (hurricane/wildfire zones push it up sharply), and HOA prevalence aren't in the PITI number. On the income side, remote work changes the equation: earning a California salary while paying Arizona costs (or vice versa) can flip the verdict.
