Is the housing market slowing down in King County, WA?
Yes — sales activity in King County, WA is down. 2,134 homes sold during May 2026, against 2,328 in the same months a year earlier, a drop of 8%.
This page is about how many homes changed hands, not what they cost. The two move separately: prices are set by the homes that did sell, and volume tells you how many people managed to transact at all. A market can hold its prices while activity quietly drains out of it.
The change clears both tests we require before naming a direction: it is more than 3% in relative terms, and it is larger than the ordinary month-to-month variation you would expect on a market that sells 2,134 homes at a time.
The longer view, all measured over the May window so the season is held constant: 2,678 homes sold two years ago, 2,328 last year, 2,134 now. Activity is meaningfully below where it was two years ago.
What is on the shelf next to what is selling: 5,982 homes were on the market in King County, WA, and 2,134 sold. At that pace it would take about 2.8 months to clear them all. There are more buyers than homes for sale. Sellers have the edge.
Every comparison on this page is to the SAME calendar months a year earlier, never to last month. Home sales roughly double between January and May in most of the country, so a month-over-month reading would tell you about the season and nothing about the market.
