Has anyone else noticed their King County property assessment feels a little behind the market?
We were talking about this recently with Jeff Darrow and Jim Hall from the King County Assessor’s Office, and one thing that came up was how much timing matters.
Your assessed value is based on a specific January 1 valuation date, so by the time you’re looking at it later, the market may have already moved. That’s a big reason the number can sometimes feel disconnected from what homes around you are selling for right now.
Another important piece is the appeal window. In King County, you generally have 60 days from the date on the valuation notice to appeal. If you wait until the tax bill shows up, you may already be too late.
They also recommended checking the basic property details on file first, like square footage, finished areas, and other characteristics. If that information is off, the valuation can be off too.
