Washington Housing Market Shifts as Inventory Reaches Highest Level Since 2014

Washington’s housing market is giving buyers more options as home listings increase and sales activity slows. According to the Northwest Multiple Listing Service (NWMLS), active listings across its 27-county service area reached 24,965 at the end of September 2026, up 24.5% from the same month last year.

The increase marks the highest September inventory level since 2014. However, while buyers have more homes to choose from, elevated mortgage rates and slower sales activity continue to shape the market.

More Homes on the Market

Buyers had more than 4,900 additional properties to consider compared with September 2025. Inventory increased in 24 of the 27 counties covered by NWMLS, indicating that the expansion in supply extends across much of the region.

Snohomish County recorded a 44.2% year-over-year increase in active listings, while King County inventory rose 31.1%.

Months of inventory reached 4.44, up from 3.25 months a year earlier. This measure estimates how long the current supply would take to sell at the month’s sales pace if no additional properties came onto the market.

More inventory can give buyers greater flexibility to compare properties, consider different neighborhoods and negotiate terms. However, conditions can vary considerably between counties and individual communities.

Home Sales Slow Despite Greater Choice

Although more properties were available, fewer homes went under contract or closed during September.

NWMLS reported 6,231 pending sales, down 15.1% from 7,335 a year earlier. Closed sales declined 8.9%, from 6,170 in September 2025 to 5,623 in September 2026. The closed-sales total was the lowest for September since at least 2014.

These figures suggest that the growth in available housing has not been matched by buyer activity. Higher borrowing costs and affordability challenges may be contributing to more cautious purchasing decisions.

Home Prices Remain Relatively Stable

Despite slower sales, the regional median sales price for residential homes and condominiums was $625,000 in September, down just 0.9% from $630,700 a year earlier.

King County’s median price remained unchanged at $850,000. Across the wider service area, the relatively modest price movement suggests that increased inventory has not resulted in a broad, sharp price decline.

Prices also differ by property type. The median price for single-family homes was $643,000, down 1.1% year over year. The median condominium price fell 4.7% to $455,000.

Condominiums Face a More Challenging Market

The condominium market showed greater weakness than the single-family segment. Pending condo sales fell 22.7% year over year, while condominium inventory reached 6.29 months of supply, up from 4.11 months in September 2025.

By comparison, single-family homes had 4.20 months of inventory, compared with 3.12 months a year earlier.

The median condo price also declined more sharply than the single-family median. These differences highlight why buyers and sellers should evaluate market conditions by property type rather than relying solely on regional averages.

Mortgage Rates Add to Affordability Challenges

Mortgage rates remain an important factor in purchasing decisions. Freddie Mac reported that the average 30-year fixed mortgage rate was 7.40% on October 15, 2026, compared with 6.95% on September 17.

Higher borrowing costs can increase monthly payments and reduce the price of a home that a buyer can comfortably afford. Even when more properties are available, financing costs may limit how many buyers are ready to move forward.

Buyers should compare mortgage offers, review their budgets and consider the full costs of ownership before making an offer.

What the Market Means for Buyers and Sellers

For buyers, the larger selection may create opportunities to compare homes and negotiate, particularly for properties that have been on the market longer. Still, desirable homes in sought-after locations may continue to attract competition, so conditions should be assessed locally.

For sellers, realistic pricing and thoughtful property preparation may be especially important as buyers have more alternatives. Reviewing recent comparable sales and seeking advice from a local real estate professional can help sellers set expectations.

The changing market also matters to homeowners associations and community managers. Shifts in home sales, property values and buyer activity can influence community turnover, resident expectations and planning for shared property maintenance. These effects will vary by community and should not be assumed from regional figures alone.

Looking Ahead

Washington’s housing market is moving into a period of greater supply and slower transaction activity. Inventory has reached its highest September level in more than a decade, but prices across the NWMLS region have remained relatively stable.

Whether this creates sustained opportunities for buyers will depend on future mortgage rates, new listings, buyer demand and local market conditions. For now, both buyers and sellers can benefit from understanding the figures for their specific county and property type rather than relying only on statewide headlines.
