New residential listings added in King County each month, 2016 to July 2026: a hard annual sawtooth peaking every spring, a step down after 2022, ranging from 672 (December 2022) to 4,684 (May 2019) and ending at 2,940.

King County sellers listed 2,940 homes in July 2026, up 5.4% from a year earlier. The series has run from 672 in December 2022 to 4,684 in May 2019.

New listings are the supply side of the inventory number, and they are the half that says something about behaviour. Active inventory is a stock — what is sitting there — and it can rise either because more people are selling or because fewer people are buying. New listings are a flow, and only sellers control it. When the two diverge, the story is demand.

The sawtooth is severe here and it is not noise: listing a house is a spring activity in this market, so the year-over-year comparison is the only one that means anything. Nothing here is seasonally adjusted.
