The equalization office utilizes a mass appraisal procedure to determine the market value of property within the county. Mass appraisal is the process of valuing a group of properties as a given date (November 1) and using common data, standardized methods, and statistical testing. Valuations for individual parcels should not be based solely on the sale price of a property, rather the valuation schedules and models should be consistently applied to a property data that are correct, complete, and up to data. Property administered, the development, construction and use of a CAMA system results in a valuation system characterized by accuracy, uniformity, equity and reliable costs per parcel. Except for unique properties where individual analyses need to be considered.
