The 98040 ZIP code in Mercer Island, WA, is a high-value Eastside residential market with roughly 10,700 housing units and property sites, including an estimated 78% single-family homes, about 19% condominiums, townhomes, and co-op-style attached residences, and approximately 3% commercial, mixed-use, institutional, or other nonresidential properties. Public-record and market-summary data through 2025 place the typical median sale price for a Mercer Island home at approximately $2.1 million, while closed-sale pricing commonly averages about $800 per square foot, with waterfront, newer construction, and view properties frequently commanding materially higher prices. Single-family houses form the core of local inventory and sales activity, generally ranging from established mid-century homes to luxury waterfront estates, while condominium and townhome options provide a smaller but important lower-maintenance segment. Over the past 10 years, the area has averaged roughly 430 residential sales per year, although annual volume has varied with interest rates, available inventory, and the limited number of homes offered for sale in this land-constrained island community. Demand is supported by Mercer Island’s Seattle and Bellevue access, highly regarded schools, waterfront setting, and a housing supply that is predominantly built out, contributing to above-average price resilience and relatively limited resale inventory compared with many neighboring King County markets.
