Market Update | March 2026 | All King County Residential | Forrest Woods Homes
Are you watching the Seattle real estate market? Wondering whether now is the right time to buy, sell, or stay put?
The March 2026 numbers are worth a close read.
I track King County housing data every month. Subscribe today for monthly market updates straight to your inbox.
Here’s my honest, data-driven take on where things stand right now.
The King County Market Is Shifting, But It’s Not What You Think
Start with the headline: the median closed sales price for King County homes in March 2026 was $975,000.
That’s essentially flat compared to $977,500 in March 2025.
We’ve seen wild swings in recent years:
+15% in 2018,
+15% again in 2021,
then a sharp -10% correction in 2023
Now? Prices have stabilized.
That’s meaningful news for both buyers and sellers. Prices aren’t crashing. They’re not spiking either.
What is changing is the balance of supply and demand, and that’s where the real story lives.
Inventory Is Rising: What That Means for You
The most significant trend in today’s Seattle housing market is rising inventory. At the end of March 2026, King County had 3,147 active residential listings, a 42% jump from the 2,222 homes available in March 2025.
Months supply of inventory now sits at 1.6 months, up from 1.1 a year ago. For context: we were at a historically tight 0.3–0.4 months supply in 2021 and 2022. Back then, Seattle was one of the most competitive real estate markets in the country. While 1.6 months still favors sellers (a balanced market runs 4–6 months), buyers now see more choices than they’ve had in years.
If you’re a seller: You still hold the advantage, but aggressive pricing no longer guarantees results.
Well-priced, well-presented homes still move fast. Homes selling in under 15 days closed at 100.2% of the original list price. That’s strong.
If you’re a buyer: More inventory means more opportunity.
The “offer by Sunday, waive inspection, no contingencies” era has softened. Homes on the market for 90+ days are being negotiated.
Those properties closed at just 92.9% of the original list price.
Mortgage Rates: A Real Silver Lining
Here’s good news for anyone sitting on the sidelines. The 30-year fixed mortgage rate in March 2026 averaged 6.18%, which is down from 6.65% in March 2025. That half-point drop translates to $316 less per month on a median-priced King County home. Over a year, that’s $3,795 in savings.
Home prices are nearly identical to last year. But your buying power has actually improved. If you stretched to afford a home in early 2025 and stepped back, this market is worth revisiting with your lender.
Speed-to-Sale: What the Data Reveals
Not every King County neighborhood performs the same way. The sales-price-to-list-price data by days on market tells a clear story:
- Under 15 days (65% of all sales): Closed at 100.2% of the original list price
- 15–30 days on market: Closed at 98.1%
- 31–60 days: 95.6%
- 90+ days: 92.9%
Pricing strategy matters enormously. A home that sits will cost a seller real money. On a $1M home, the difference between an overpriced listing and a well-priced one can exceed $70,000 in net proceeds.
Who’s Buying Where, and at What Price
The closed sales data reveal where buyer demand concentrates in King County right now.
The $500K–$750K range still drives the highest volume with 350 sales in March. But that’s down 11% year over year, and affordability pressure continues to squeeze entry-level buyers.
The $1M–$1.25M range is up 13% year over year.
Ultra-luxury properties ($5M+) saw closings jump 14% in March.
The higher end of the Seattle market shows real resilience.
The biggest pullback?
The $1.75M–$3M range is down 20–24%.
Buyers in that segment are being more cautious. Some sellers haven’t adjusted their pricing expectations yet. My boots-on-the-ground experience has been that Buyers are loving the new construction options in this price point and are expecting more renovations from resale homes.
If you’re thinking about a renovation project in 2026 to prepare your home for the market, let me know. I’d be happy to help you determine what might get you the most ROI.
The Affordability Reality
King County’s median household income runs about $118,664 per year, or roughly $9,889 per month.
At current prices and rates, the principal and interest payment on a median-priced home is $5,959 per month.
That’s 73% of the median monthly income in King County. Woof.
That number is significant. It explains why the Seattle market isn’t seeing a buying frenzy, even with better inventory and lower rates.
Affordability remains a real structural challenge for first-time buyers. Dual-income households, remote-work tech buyers, and move-up buyers continue to drive activity.
What This Means for You in 2026
Thinking about selling? The seller’s advantage remains open, but the window may narrow. Spring 2026 is peak listing season in the Seattle area. Inventory is already up 42% year over year. Getting ahead of more competition and presenting your home at its best now is a smart move.
Thinking about buying? You have more negotiating room than at any point since 2019. Rates are better than 12 months ago. Prices have stabilized. Waiting has real carrying costs, both financial and in missed opportunities. Rates can move in either direction from here.
Not moving anytime soon? Knowing your home’s current value still matters. King County homeowners have seen significant appreciation over the past decade. Understanding your equity position is valuable for financial planning.
My Take
The Seattle and King County real estate market in spring 2026 is nuanced. It’s not the frenzy of 2021.
It’s not the correction of 2023. It’s a market in recalibration. The fundamentals remain strong: limited new construction, steady demand from the region’s tech and healthcare employment base, and a lifestyle that keeps attracting buyers from around the country.
