King County listings under contract at month end, 2017 to September 2026, seasonal peaks each spring, ending at 1,948.

1,948 King County listings were under contract at the end of September 2026, down 17.7% from a year earlier. Pending sales are the closest thing this site carries to a leading indicator of the housing market: a deal goes pending weeks before it closes, so this line turns before recorded sale prices do.

It is also the demand side of the same monthly Realtor.com drop that gives us inventory and asking prices. Inventory rising while pendings fall is a market cooling; both rising together is just a busy spring.
