HERE is a link to King County Property Tax information from the County website.

Below is some of the information.

Tips for filing an appeal:
  1. File online using eAppeals!  This will allow you to check on the current status of your appeal at any time and allow you to instantly view appeal related documents sent to you by the Board of Equalization and the King County Assessor.
  2. Include all evidence with your appeal, or submit it as soon as possible.  An early submission will increase the possibility of receiving a reduction offer from the Assessor without having to attend a hearing.  Examples of useful types of evidence include but are not limited to:
    • Sales info of similar properties with sales dates close to the valuation date
    • Professional cost estimates to fix any structural defects or maintenance issues
    • Recorded documents that reference any easements or other restrictions on the property
    • Official communications or documentation from city, county, or an environmental agency confirming environmentally critical areas exist on the site, and/ or any development limitations affecting the property

In order to succeed on a valuation appeal you need to have at least two comparables from as late in  December as you can get, since the valuation is based on January 1st, that are both at least 10% below the value of your home. 

That means a match of type of home, year, location, square footage, bedrooms, and bathrooms in the correct time period with a low enough value.  This is very difficult to do because values are often slightly depressed in December. 

When you calculate the multiple used to translate market value into assessed value, even swings of tens of thousands of dollars don’t make that much difference in your tax bill.  I am sorry to be the bearer of bad news, but I have had a lot of clients try and fail to get a meaningful adjustment based on comps.  The more likely to succeed approach is something particular to the property such as pictures of structural damage, black mold, or a neighborhood change like a new light rail interfering with your property.
