Many home buyers across King County, Washington are setting their sights on the remaining months of 2025 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 2025, 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 January 2025.

King County Home Prices Are Rising Quickly in 2025

The prices of homes in King County rose sharply from 2012 to mid-2018. But since then, price appreciation has slowed. In fact, home prices actually fell from mid-2018 through mid-2019. However, home prices have been soaring over recent months, so you can expect prices to be higher by the end of 2025 compared to where they were at the start of the year.

According to Zillow, the median price paid for a single-family home across King County is $848,022 as of January 2025. That was an increase of roughly 4.8% from the same month a year earlier. But prices are expected to increase more this year. 

So that’s the first thing you should know, if you’re planning to buy a home in King County in 2025. As a result of steady and significant price growth, buyers across the county will encounter higher housing costs in 2025.

Expect Competition From Other Buyers

King County home buyers should be prepared for fierce competition in 2025 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 2025.

According to housing experts, a “balanced” real estate market has about five to six months worth of supply. As of early 2025, King County, Washington had only a 2-month supply of homes. That’s well below the national average.

Additionally, homes spent a median of just 17 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.

Mortgage Rates Remain High

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 mid 7% mark. According to a recent report by Freddie Mac, the average rate for a 30-year fixed home loan was 6.85%. So, interest rates continue to remain relatively high for King County home buyers and mortgage shoppers.

The latest data from Freddie Mac suggests that rates could dip to 6% by the end of 2025.

So that’s a look at the King County housing market and mortgage trends for 2025. If you’d like to learn more about this subject, check out these housing forecasts for the area.
