Chelan County Assessor

Market Sales Analysis

Every year, the Chelan County Assessor's Office statistically updates all taxable real property in the county using adjustments derived from analysis of recent comparable market sales in accordance with Washington State Law.  The sales analysis dictates the statistical adjustments in different classifications of properties by type and location.  If assessed values are significantly different from sale prices, we will apply a market adjustment factor to that neighborhood of properties in order to bring the assessed value closer to sales prices.
