King County is the largest housing market in Washington, and prices swing a lot from one city to the next. Use the search to browse every active listing, or pick a city on the right to narrow it down.
Prices are down about 6% from last August, and there is more to choose from. Single-family homes for sale are up 40%, and the market holds about 3.8 months of supply, up from 2.6 a year ago. Buyers have more room to choose and negotiate. Sellers need to price carefully from day one.
