Many home buyers across King County, Washington are setting their sights on 2026 when it comes to whether or not to buy a home. And many share the same questions: Is it a good time to buy a home in King County? What will the real estate market be like next year?
We’ve created a King County mortgage and home buying guide for 2026, to help you make an informed decision about when to buy. Here’s an updated look at current mortgage and housing market trends for the county, as of February 2026.
Price appreciation has slowed in King County over the past year. According to Zillow, the median price paid for a single-family home across King County is $837,279 as of February 2026. That was a decrease of roughly 2.0% from the same month a year earlier.
But home prices in King County are projected to edge upward in 2026 as demand continues to outpace the supply of available homes.
Population growth and limited new construction are expected to keep upward pressure on prices.
Even modest interest‑rate relief could bring more buyers back into the market, adding to competition.
Overall, analysts anticipate steady, gradual appreciation rather than dramatic spikes.So that’s the first thing you should know, if you’re planning to buy a home in King County in 2026.
King County home buyers should be prepared for fierce competition in 2026 due to a shortage of housing inventory across the county.
Like most of Washington State, the real estate market in King County has suffered from limited supply over recent years. And these conditions will likely continue further into 2026.
According to housing experts, a “balanced” real estate market has about five to six months worth of supply. As of early 2026, King County, Washington had only a 2-month supply of homes. That’s well below the national average.
Additionally, homes spent a median of 42 days on the market before going under contract.
All of these trends indicate a strong seller’s market. High demand and low inventory have created a highly competitive market for home buyers in King County, Washington, and across the broader Seattle metro area.
In previous blog posts, we explained that mortgage requirements have eased a bit over the last few years. This applies to debt ratios, credit scores, and other criteria used to approve borrowers for home loans.
However, it’s still relatively challenging to get a mortgage these days, especially as home price rise and rates remain high.
Mortgage rates for King County, Washington have been hovering around the low 6% mark. According to a recent report by Freddie Mac, the average rate for a 30-year fixed home loan was 6.10%. So, interest rates continue to remain relatively high for King County home buyers and mortgage shoppers, but they’re expected to decrease over the coming months.
The latest data from Freddie Mac suggests that rates could dip to 6% by the end of 2026.
