Valuation Process


For the 2019-2020 appraisals, the actual value assigned to vacant land, residential and commercial properties is based on sales and other market data from January 1, 2017 through June 30, 2018. This data gathering period called the base period, is prescribed by Colorado statutes. However, if an insufficient number of comparable sales occurred during that timeframe, the assessor is authorized to analyze sales that occurred up to five years preceding June 30, 2018. All sales or market data is adjusted for time to the June 30, 2018 appraisal date.

Changes in the economic data after the June 30, 2018 appraisal date cannot be considered until the next general reappraisal.

For 2020, property values will not change from 2019 unless there have been changes to the property, such as new construction or additions, or unless there has been a change in the use of the land.

For agricultural property, mobile homes and or businesses, the valuation process is explained in the following brochures:
