The listing data relating to real estate for sale on this web site comes in part from the Northwest Multiple Listing Service. Real estate listings held by brokerage firms other than Costello Team | Windermere Real Estate are marked by the "three tree" symbol; detailed information about such listings includes the names of the listing brokers. Data last updated 2022-07-07T00:16:11.613. The "Days on Site" data field is calculated by BoomTown and is the number of days since the listing was originally received in our system. It is not the equivalent of "Days on Market".
