How is property appraised in New Hampshire?

In New Hampshire, municipalities are required to adjust property values at least every five years to keep in line with market values. Accurate appraisals require constant searching for significant facts to accumulate and analyze, in order to estimate the fair market value of properties. For a revaluation, the assessor first reviews all the property to be assessed, and then places values according to their fair market value. In addition, properties that have had changes that affect value are adjusted annually to reflect those changes, so that all assessments are reasonably proportional within the town.
