Seattle-Area Real Estate Update | October 2025 Market Trends Across the Eastside, Mercer Island, Bainbridge Island & King County

October’s housing data across the Seattle metro area reveals a market that’s recalibrating rather than cooling. While inventory remains above 2024 levels, seasonal slowdowns are visible — with fewer new listings and slightly longer days on market. Yet, buyer activity has held steady, supported by expectations of rate cuts and the push to buy before a potentially more competitive spring.

Below, we break down the numbers and key takeaways for each submarket.
