Foreclosure costs are added to the amount due when the initial foreclosure warning is mailed in February of the each year. These costs continue to accrue until the parcel is redeemed or sold.

When real property taxes become a full three years delinquent, the county treasurer begins foreclosure action.  A Certificate of Delinquency is filed with the Superior Court.  In addition to taxes, assessments, fees, interest and penalties, costs of foreclosure begin to accrue. 

Title searches are conducted on each of the parcels subject to foreclosure.  As required by law, all parties with a recorded legal interest revealed by this search are served by certified or registered mail with a “Notice and Summons”, which is also published in the Seattle Times.

A “Judgment Granting King County’s Application to Foreclose Tax Liens and Order of Sale” will be granted.  Parcels can be redeemed by their owner(s) or parties with a recorded legal interest until 4:30 pm on the day before sale.

Parcels will be sold at auction online through our on line auction vendor.

To avoid being included in the 2022 foreclosure action, payment for 2019 and any prior years must be paid no later than October 31, 2022. The 2022 Certificate of Delinquency is scheduled to be filed November 2022.

Parcels can be redeemed by their owner(s) or parties with a recorded legal interest until 4:30 pm on the day before sale.

Once the Certificate of Delinquency has been filed, we are only able to accept payment in full of ALL year’s taxes, fees and assessments plus interest, penalties and costs of foreclosure to remove the parcel from the foreclosure action.
