Determining the value of every property is called valuation. The Assessors are required to value property at market value. Each property is revalued at least once every three years and inspected at least once every ten years in accordance with Massachusetts’s law. Occasionally property-selling prices indicate that market values have changed significantly in the past year. When this occurs, the Board is required to make interim year adjustments to bring the valued within the requirements outlined in the “Guidelines to a Minimum Reassessment Program”. The most recent town-wide revaluation in Manchester was for fiscal year 2014. The assessment records can be accessed at the Assessors’ Office or on the assessors website.
