Mercer Island Homes Offer Eastside Value Without Seattle's Steepest Prices

Mercer Island recorded 47 single-family home sales in the second quarter of 2026 at a median price of $1.85 million, according to King County assessor data released this week.

The figure arrives as downtown Seattle condo prices climbed 9 percent year over year and inventory tightened further after the spring selling season. Mercer Island's position on the I-90 corridor continues to draw commuters who want quick access to both the city core and Eastside employers while avoiding the highest per-square-foot costs in neighborhoods such as Capitol Hill or Queen Anne.

Proximity and local anchors

Residents point to the island's own Mercer Island Community Center on 78th Avenue Southeast and its connection to the Stroum Jewish Community Center as steady draws for families. The 1.5-mile bridge link to Seattle also places the island within a 15-minute drive of the University of Washington's main campus for many households.

Those amenities have kept turnover low. Only 12 percent of Mercer Island's housing stock changed hands in the past 12 months, compared with 19 percent across King County overall.

Price data and next steps

Current listings show three-bedroom homes on Southeast 36th Street priced between $1.65 million and $1.95 million, figures that remain 12 percent below equivalent properties in adjacent Bellevue. Buyers who close before the end of August can still lock in 30-year fixed rates near 6.4 percent through local lenders that participate in the Washington State Housing Finance Commission program.

Prospective owners should check the city planning department's online portal for any remaining lots under the Mercer Island Comprehensive Plan update scheduled for final adoption in September.
