Snohomish County Housing Market Update: September 2026 Numbers & What They Mean

If it feels like there are suddenly a lot more for-sale signs around Snohomish County, you’re not imagining it. The Northwest Multiple Listing Service (NWMLS) released its official September 2026 statistics on October 6, and the headline for our county is hard to miss: inventory is up 44.2% from a year ago — the biggest jump in the Puget Sound core. Here’s my plain-English breakdown of what the numbers say, and what they mean if you’re buying or selling in Edmonds, Lynnwood, Everett, Lake Stevens, Marysville, or anywhere in between.

Every figure below comes straight from the official NWMLS release — no guesswork, no hype.

What Happened in the Snohomish County Housing Market in September 2026?

Buyers gained significantly more choices while prices stayed resilient: Snohomish County’s active inventory jumped 44.2% year over year — the largest increase among King, Snohomish, and Pierce counties — yet at 3.85 months of supply, our market remains tighter than King County’s 4.70.

Across the whole NWMLS service area, active listings reached 24,965 in September, up 24.5% year over year and the highest level since 2014. Statewide months of inventory hit 4.44 — a mark last seen in February 2014 — while closed sales fell 8.9% to 5,623, pending sales dropped 15.1%, and 9,996 new listings came on the market (up 8.7%). The statewide median sale price was $625,000, down just 0.9% from a year ago.

What Is the Median Home Price in Snohomish County?

Snohomish County’s median sale price was $720,000 in September 2026 — the third-highest of any county in the NWMLS service area.

That’s essentially in line with late summer — NWMLS’s August release put our median at $724,500 — and it keeps Snohomish County positioned as the more attainable neighbor to King County, where the September median held at $850,000. For many of my buyers, that roughly $130,000 gap is exactly why they’re shopping on this side of the county line.

How Much Inventory Is There in Snohomish County?

Snohomish County had 3.85 months of inventory in September — up dramatically from a year ago, but still the tightest supply among the three core Puget Sound counties.

King, Snohomish, and Pierce counties together held 57% of all active listings in the NWMLS system, with tri-county inventory up 31.2% to 14,294 homes and months of supply at 4.27, up from 2.91 a year earlier. Our county’s 44.2% inventory surge was the largest of the three — yet even after that jump, we’re still under the four-month mark many analysts use as the threshold of a balanced market, while King County has moved past it.

Is It a Buyer’s Market or a Seller’s Market in Snohomish County?

We’re moving toward balance: at 3.85 months of supply, Snohomish County still leans slightly toward sellers on paper, but the momentum is clearly with buyers.

Pending sales across the tri-county area fell 16.4% year over year, statewide closed sales dropped 8.9%, and the average listing statewide received 4.2 showings in September, down from 5.2 a year ago. Translation: fewer buyers are actively competing, and the ones who are in the market have options — and negotiating power — they haven’t had in years.

What Does This Mean for Buyers?

September delivered the widest selection Snohomish County buyers have seen in roughly a decade.

• More homes to choose from. A 44.2% jump in inventory means neighborhoods that had nothing for sale last fall now have real options — and you can take time to compare instead of racing to the first open house.

• Room to negotiate. With fewer competing buyers, inspection negotiations, contingencies, and seller concessions are back on the table.

• Down payment help is widely available. NWMLS reports 74.7% of active listings qualified for at least one down payment assistance program — my Washington down payment guide covers what you might qualify for.

• Builders are competing too. With record resale inventory, new-construction incentives get sweeter — my new construction buyer’s guide walks through how to negotiate with builders.

What Does This Mean for Sellers?

Selling in Snohomish County still works — ours is the tightest supply in the Puget Sound core — but the days of simply naming your price are behind us.

• Price with today’s market, not last spring’s. With 44% more competition on the market, the right list price is what earns showings in the first two weeks — when they matter most.

• Lead with condition. Buyers with options gravitate to homes that are clean, repaired, and well presented. Small prep investments pay off now.

• Know your net before you list. My guide to the cost of selling a house in Snohomish County breaks down excise tax, closing costs, and what actually lands in your pocket.

• Stay strategic on offers. Longer timelines and negotiation requests are normal in a balancing market — the goal is the strongest net outcome, not just the fastest yes.

Snohomish County Housing Market FAQ

Are Snohomish County home prices dropping?

Not meaningfully. The September median was $720,000 — third-highest in the state and roughly in line with late-summer levels — while the statewide median eased just 0.9%. As Steven Bourassa, director of the Washington Center for Real Estate Research, noted in the NWMLS release: “Prices tend to rise quickly in a strong market but can be slower to fall when conditions weaken.”

Why is inventory rising so fast in Snohomish County?

Two forces are stacking: more homeowners are listing (new listings were up 8.7% statewide in September) while homes are taking longer to go pending (pending sales fell 15.1% statewide). The pattern is regional — total NWMLS inventory reached its highest level since 2014 — but Snohomish County’s 44.2% jump was the sharpest in the tri-county core.

Is now a good time to buy a home in Snohomish County?

If selection and negotiating room matter to you, this is the most buyer-friendly stretch in about a decade. The right answer still depends on your finances, your timeline, and the specific home — which is exactly the conversation I’d love to have with you, no pressure attached.
