Inventory Rises, Prices Ease Across Washington

Published on: October 6, 2025

Northwest Multiple Listing Service (NWMLS), the source for the most current, accurate market listing data in Washington state, today released its September 2025 Market Snapshot.

Market Recap

Inventory is climbing, giving buyers more options, while home prices are showing signs of moderation after years of rapid growth. The median sales price in September dipped 0.7% year-over-year, from $635,000 to $630,700, and fell 3% month-over-month from August’s $650,000. Similar month-over-month declines were seen in King, Snohomish, and Pierce counties. Interest rates have declined slightly, but not enough to significantly impact the market.

“House prices in the NWMLS service area have generally been sluggish in response to high interest rates,” said Steven Bourassa, Director of the Washington Center for Real Estate Research at the University of Washington. “Initially, high interest rates discouraged both sellers and buyers, but in recent months, sellers have been listing properties at a faster rate than buyers have been purchasing them. To some extent, these changes may reflect typical seasonal fluctuations, but at some point the laws of supply and demand may prevail, and prices may lose some of their stickiness.”

“Seattle’s housing market is continuing to rebalance following large swings in prices and demand in the last few years,” said Selma Hepp, Chief Economist at Cotality. “Improved affordability is certainly helping attract home buyers – especially for mid-range and tech-enhanced homes, that are now facing less competition than in the years prior. Home prices are expected to move sideways and pick up again in early 2026 with the spring home buying market, though overall rate of appreciation will be slower as buyers’ incomes catch up and affordability remains the top concern.”
