Reassessment
The periodic revaluation of everything in a jurisdiction.
Jurisdictions revalue on a cycle — annually in some places, every three or four years elsewhere. A reassessment year is when large changes appear, and when appeal volumes rise.
A big increase in a reassessment year is not by itself evidence of error; values may genuinely have moved. What matters is whether your increase is out of line with comparable properties, which is a uniformity question.
