Mercer Island sits in the middle of Lake Washington, linked by I-90 to both Seattle and Bellevue and now served by light rail. It's prized for privacy, mature trees, lake access, and one of the state's strongest school systems — all within a genuinely short commute to either downtown.
Housing skews toward larger single-family homes and waterfront estates, with a tight-knit town center. Inventory is limited and demand is consistent, so well-prepared buyers and strategically priced sellers both do best here.

The feel of the place
Leafy, private, and quietly affluent — an island of mature trees and lake views that feels removed yet sits minutes from two downtowns. A close-knit community with its own town center and top schools.
