Inventory changes the conversation

ARMLS reported 23,406 active listings and 4.28 months of supply for August. That supply measure was 3.77 months in July. More time and selection can improve a buyer’s ability to compare alternatives, but a marketwide average does not tell us whether a well-priced home in a particular subdivision faces the same competition.

Closed sales softened; contracts moved the other way

July and August are often quieter months in Greater Phoenix: extreme heat and the return to school can lead some households to wait for cooler weather and a settled routine before shopping. That seasonal tendency is context, not proof of what drove a particular sale. August closed sales fell to 5,471 from 6,298 in July, a 13.13% decline. They were also 7.65% below August 2025, which makes the year-over-year comparison worth watching. Meanwhile, homes under contract rose from 6,638 to 6,913. Contracts can lead closings, but some fail or change timing; one month does not establish a lasting recovery.

Prices need a closer reading

The median sale price eased from $450,000 in July to $445,000 in August, yet remained above the $440,000 recorded a year earlier. The median list price rose from $455,000 to $462,740. These two medians describe different groups of properties, so their difference is not a measure of the discount an individual seller accepted. It does suggest checking current asking prices against recent comparable sales before making an offer or setting a price.

Marketing time lengthened too: median days on market rose from 61 to 64, and the average reached 88. More days do not automatically imply a price cut on every home. Condition, location, financing terms and the quality of comparable sales still determine what a particular property can command.
