Others have provided you information from the public records (below). Be advised, the public records are not always accurate, or up to date. Divorce, death, transfer of ownership, quit claim, foreclosure actions, and liens may be recorded against a given property and the public records may not reflect that data for weeks. Your best source of information might be an in-person visit to the King County Assessor's department. or a title review by a title company. Good luck.
