Greater Seattle & Puget Sound Real Estate Market Update – September 2026

The Greater Seattle and Puget Sound housing market is entering fall 2026 with a noticeable shift from the highly competitive conditions buyers have experienced in recent years. More homes are coming onto the market, buyers have more opportunities to compare properties, and sellers are facing a more selective audience.

According to the latest Northwest Multiple Listing Service (NWMLS) data, there were 24,675 active listings across the NWMLS service area at the end of August, a 22% increase from August 2025. At the same time, closed sales declined 7.6% year over year. The regional median sales price for homes and condominiums was $635,000, down 2.3% from a year earlier.

For buyers, this means more breathing room. For sellers, it means preparation, pricing and presentation matter more than ever.

King County: More Inventory, More Negotiating Room

King County remains one of the most expensive markets in the region, with an August median sales price of $845,000. That's down 3.4% from August 2025.

More significantly, King County had approximately 4.3 months of inventory in August, compared with 2.9 months a year earlier. Four to six months of inventory is generally considered a balanced market, suggesting that King County is moving away from the seller-dominated conditions that have characterized much of the past several years.

For buyers, additional inventory can mean more choices and greater opportunity to negotiate. Sellers, meanwhile, need to understand that buyers may be comparing their home against considerably more competition.

Snohomish County Continues to See Strong Inventory Growth

Snohomish County has experienced one of the largest increases in available homes in the region. Active listings were up 39.3% year over year in August.

The August median sales price was $724,500, making Snohomish County an important option for buyers looking for alternatives to King County while still remaining within the broader Puget Sound employment and transportation network. Snohomish County had approximately 3.64 months of inventory at the August sales pace.

Pierce County Remains Relatively Tight

Pierce County continues to offer a somewhat different market dynamic. It had approximately 3.33 months of inventory in August, lower than King County's 4.3 months.

That means buyers may still encounter competition for well-priced, desirable properties, particularly those offering good condition, convenient locations and attractive price points.

What This Means for Buyers

Today's market can offer buyers more flexibility than they've had in recent years.

With inventory expanding and sales activity slowing, buyers may have more time to evaluate a home carefully rather than feeling pressured to make an immediate decision. There may also be more opportunities to negotiate price, inspection terms, closing dates or other elements of a transaction.

That doesn't mean every home is a bargain. Desirable properties that are correctly priced and well presented can still attract strong interest.

The key is preparation. Buyers should understand their financing options, know their comfortable price range and be ready to act when the right property appears.

What This Means for Sellers

For sellers, the changing market makes accurate pricing especially important.

When buyers have more choices, an overpriced home can sit on the market while competing properties attract attention. Today's sellers should consider the condition of their property, recent comparable sales, current competition and the expectations of today's buyers.

Professional photography, thoughtful preparation and a marketing strategy that highlights a home's strongest features can also make an important difference.

Most importantly, sellers should work with their broker to establish a realistic pricing strategy before going on the market—and be prepared to respond to changing market feedback.

Looking Ahead to Fall

The Puget Sound market appears to be moving toward a healthier balance between buyers and sellers. Inventory is substantially higher than it was a year ago, while prices have softened modestly rather than experiencing a dramatic decline. At the same time, higher borrowing costs continue to influence how much buyers can comfortably spend and how quickly they make decisions.

The result is a market where local knowledge matters.

Conditions can vary significantly from one neighborhood to another, and countywide statistics don't tell the entire story. A home in Seattle, the Eastside, North King County, Snohomish County or Pierce County may experience a very different level of demand depending on its location, price range, property type and condition.

The Bottom Line

The Greater Seattle and Puget Sound real estate market isn't standing still—it's evolving.

Buyers have more choices. Sellers need to be more strategic. And well-priced, well-prepared homes continue to stand out.
