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 | Real Broker, LLC are marked by the "three tree" symbol; detailed information about such listings includes the names of the listing brokers. The three tree icon refers to an NWMLS listing. Data last updated 2025-01-15T13:16:21.137. 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".
Based on information submitted to the MLS GRID as of 2025-01-15T13:16:21.137. All data is obtained from various sources and may not have been verified by broker or MLS GRID. Supplied Open House Information is subject to change without notice. All information should be independently reviewed and verified for accuracy.
