How we compute
the numbers

Every market report figure is computed from the sources below, read from the data each time a page is built. Published rules and survey figures on the selling and buying pages, such as lender rules, statutes and commission surveys, are quoted from their publishers and named where they appear. We check the published sources every day.

Where the data comes from

Arizona law behind the sold lists

A sale is recorded with its price

When a home sells in Arizona, the deed is recorded with an affidavit from the buyer and the seller that states the date of sale and the total price paid. The county recorder refuses a deed without one, unless the deed notes an exemption.

A.R.S. § 11-1133, read in full at azleg.gov on October 21, 2026.

Some transfers carry no public price

Gifts, transfers between close family for a nominal amount, trustee's deeds after a foreclosure sale, deeds made under a court order and some others are exempt from the affidavit, so they have no public price. That is why our sold lists are not every sale.

A.R.S. § 11-1134, read in full at azleg.gov on October 21, 2026.

What each number means

  1. 01

    Typical home value and its change

    Zillow's home value index for the area in its latest month, compared with the same month one year and five years earlier. It describes a typical home, not any one house.

  2. 02

    Homes for sale compared with a usual month

    The latest month's homes for sale compared with the average for the same calendar month in every earlier year of Realtor.com data (since 2016).

  3. 03

    City figures

    Realtor.com publishes no city totals, so a city's listings and price cuts are added up across its ZIP codes, and its days on market is the average of those ZIP codes, with each ZIP code counting in proportion to its number of listings. City home values and sales come from Zillow's and Redfin's own city figures; Redfin's city sales are three-month averages.

  4. 04

    Prices against local incomes

    Today's typical home value divided by local household income, compared with the average of that same ratio from 2000 to 2019. Household income comes from the Census Bureau's five-year survey, moved up or down to each year by the change in the Bureau's yearly county income estimates.

  5. 05

    What it costs to buy

    The monthly payment on the typical home with a standard down payment at Freddie Mac's latest weekly average rate, plus property tax (the Census median taxes paid, as a share of value) and insurance (the 2022 premium, brought to today with the Bureau of Labor Statistics price index for homeowners insurance premiums). “Income needed” assumes housing takes 30 cents of every dollar a household earns.

  6. 06

    The owners here

    Counted from county property records and the property data company's estimates: homes with no mortgage, time since the last recorded sale, owners who bought before 2012 and VA loans among owner-occupied homes, and company ownership among all properties on record. A figure appears only when at least 200 records support it and it is known for at least 6 in 10 of the homes it describes.

  7. 07

    What actually sold

    Ten homes sold and recorded with the Maricopa County Recorder in the latest month that ended at least 45 days ago (or the month before, when it has fewer than ten), spread from the 5th to the 95th percentile of price, with the middle half of the month's sales printed in dollars. Homes only, from $75,000 to $5,000,000; vacant lots, commercial units and one price paid for several parcels are left out. Dates show month and year only, because many recorder dates are rounded to the month.

Known limits

  1. 01

    Not every sale has a public price

    Sales recorded with an exemption under A.R.S. § 11-1134 have no public affidavit, so they are not included and our sold lists do not show every sale.

  2. 02

    Data estimates, not appraisals

    Value estimates for a single home are data estimates, not appraisals. Records can't see your home's condition, renovations or upgrades, which can move a final price by tens of thousands of dollars.

  3. 03

    Small counties

    Areas with few sales each month produce jumpy figures, so five small counties appear only in the statewide table rather than on pages of their own.

  4. 04

    Home insurance starts from the 2022 premium

    The insurance figure in the cost to buy is the 2022 average premium for the ZIP code, brought to today with the Bureau of Labor Statistics price index for homeowners insurance premiums. It is an average, not a quote for any one home.

  5. 05

    The sold lists run behind

    They show the latest month that ended at least 45 days ago (today that is August 2026), because a month's recorded sales keep arriving for weeks after it ends, and they cover Maricopa County only.

  6. 06

    Arizona's statewide rent

    Zillow publishes no statewide rent figure, so the Arizona page shows no typical rent; each area and city page shows Zillow's own.

  7. 07

    Owner figures in some rural areas

    In some areas our records hold these figures for fewer than half of owner-occupied homes: 31,504 of 91,368 homes in Prescott & Yavapai County, and 19,008 of 40,582 homes in Flagstaff & Coconino County.

  8. 08

    Publishers revise their latest month

    A publisher can revise its latest month as more sales are reported, so a figure here can change after it first appears.
