Chelan County Assessor

Department of Revenue Valid Sales Study

To provide uniform taxation statewide, the Department of Revenue (Department) implements an annual study of property in each of the state's 39 counties. This piece of the 2017 ratio year study measures how closely Chelan County's 2016 single-family residence assessed values compare to market values. The study consists of two analysis where the Department selects a random sample of 60 sales from Chelan County's valid single-family residential sales report. These sales are then compared to comparable non-selling properties to determine if selling and non-selling properties are being assessed similarly.
