These sales are used for the 2019/2020 tax years. Use the time-adjusted sales prices if appealing your property assessment.
Comparable properties are often found in the same Market Area, which are groups of neighborhoods that have similar trends in the market. Boulder County uses these areas to establish market value for mass appraisal purposes. Your market area number is listed on your full-page Notice of Valuation (not the postcard) on the lower left side of the page below your property address and account number.
