Within three miles of Seattle or Bellevue, the Mercer Island Coldwell Banker Bain real estate office is centrally located in the heart of MI's downtown. Its qualified professional agents are happy to assist you in selling or finding a home on Mercer Island or the surrounding Puget Sound area. Coldwell Banker Bain has always been a civic minded group of realtors, carrying on traditions of the daffodil bulb giveaway in the fall, Toys4Tots in December and lining Island Crest Way and Mercer Island's main streets with American flags each 4th of July.
