Massachusetts law requires that all municipalities establish the full and fair cash value of all real estate as of January 1 of each year. FY2019 values are determined as of January 1, 2018. To determine FY19 values, the Assessing Department reviewed all valid sales that occurred between January 1, 2017 and December 31, 2017. A "Mass Appraisal" computer software model is used to calculate property values based on this market activity as well as certain property-specific attributes such as location, size, construction quality, style, and condition. The Town uses Paul Kapinos and Associates (PK) as its software program.
