Moving to Arizona from California.

What actually changes in your budget, what gets cheaper, what quietly gets more expensive, and the parts most people do not find out until the first summer.

Californians are the largest group of people moving to Arizona, and it is not close. About 52,400 people moved from California to Arizona in 2024. The next closest state was Washington at roughly 17,600, then Texas at about 10,300 (U.S. Census Bureau American Community Survey data, compiled by USAFacts).

I have this conversation most weeks, and it is almost always about money. So here is the honest version with the numbers attached and the sources named, so you can go check them yourself instead of taking my word for it.

1. Housing is the number that moves the most

California's statewide median price for an existing single family home was $887,680 in July 2026, up 0.3 percent from a year earlier, according to the California Association of Realtors report released August 17, 2026.

In Greater Phoenix, the median sale price in July 2026 was $450,000, up about 2.3 percent year over year, based on ARMLS data. Months of supply sat near 3.8 and homes were closing at roughly 99 percent of list.

That is a gap of more than $430,000 on the median. It is not a perfect comparison, because the housing stock is different in age, lot size and square footage, and a statewide California median is dragged up by coastal metros. But the direction is not subtle, and it is the single reason most of these moves happen.

What that budget buys here is usually the thing people are actually chasing. A newer build with four bedrooms, a real yard, a garage that fits two cars and a truck, and a pool you will use eight months a year. Standing in your own kitchen at seven in the morning with the slider open and coffee going, before the heat arrives, is the version of Arizona that makes people stay.

2. Income tax is the second biggest line

Arizona has a flat individual income tax of 2.50 percent. California's individual income tax runs from 1.00 percent to 13.30 percent depending on income. Both figures are from the Tax Foundation's 2026 state tax data.

How much that saves you depends entirely on your income, so I am not going to hand you a number. What I will tell you is that the year you move is the messy one. Part year residency rules, where your income is sourced, and the timing of selling your California home can all change the math significantly. That is a conversation for a CPA who handles both states, and it is worth having before you list, not after.

3. Property tax usually favors Arizona, with one big exception

The Tax Foundation puts Arizona's effective property tax rate at 0.48 percent of owner occupied housing value for 2026, against 0.70 percent in California.

Here is the exception, and it catches long time California owners every time. Under Proposition 13, your California assessed value has been capped since the year you bought. If you have owned that house since 1998, your tax bill is calculated on a number that has nothing to do with what the house is worth today. So you may be paying a higher rate on a much lower base, and your actual dollar bill in California could be lower than what you will pay here.

4. Sales tax is roughly a wash

Arizona's state sales tax is 5.60 percent, with a combined state and local average of 8.52 percent. California's state rate is 7.25 percent with a combined average of 8.99 percent (Tax Foundation, 2026). Close enough that it should not be part of your decision. Arizona's local rates vary a lot by city, so if you are comparing two specific addresses, look up those two cities rather than trusting the state average.

5. The costs nobody warns you about

This is the part I care most about, because it is where the budget quietly breaks after you have already moved.

6. The heat, said plainly

Phoenix Sky Harbor's 1991 to 2020 climate normals put the average annual temperature at 75.6 degrees and average annual rainfall at 7.22 inches, according to the National Weather Service Phoenix office.

Those averages hide the shape of the year. October through May is the reason people move here. June through September is the price of admission. In those months life moves indoors, or to six in the morning, or into the water. Arizona's monsoon season runs June 15 through September 30, which brings dust, hard wind and sudden rain, and it is the reason roofs and drainage matter more here than they did where you came from.

If you can, visit in July before you commit. Everyone visits in February and falls in love. Visiting in July is the honest test.

7. Where Californians actually land

The East Valley takes most of them. Gilbert, Chandler, Mesa, Queen Creek and San Tan Valley are where families and remote workers tend to end up, because that is where the newer inventory, the newer schools and the master planned communities are. Central Phoenix and the historic districts pull the people who want walkability and older architecture and are willing to trade square footage for it. Scottsdale pulls its own crowd and prices accordingly.

One thing worth understanding early: the Valley is not one market. In the same month, some cities can be firmly in seller territory while others sit clearly in buyer territory. That spread is real and it moves every month, so ask for current city level numbers rather than reading a national headline and assuming it applies to the address you want.

8. Rent first, or buy right away?

There is no universal answer, and the things that decide it are not on a listing site. Where your work actually is, what your household needs day to day, and which parts of the Valley fit the way you want to live.

That is a short conversation and I would rather have it early. Tell me those three things and I will narrow thirty possible areas down to three or four that genuinely fit, and tell you what each one costs. If the honest answer turns out to be that you should rent for six months first, I will say so, and I will help you find the rental.

The short version

Housing and income tax are where the real savings are. Property tax usually favors Arizona unless Proposition 13 has been protecting you for decades. Sales tax is a wash. Utilities, insurance, HOA dues and pool upkeep are where people overshoot their budget, because those are the numbers nobody puts in a relocation article.

Every figure above has a source and a date on it on purpose. Housing numbers move monthly and tax rules change, so if you are reading this well after it was published, ask for current numbers before you plan around it.
