Transitional assessed value

For larger residential and commercial properties, assessment increases and decreases phase in over several years rather than landing at once. The transitional assessed value tracks that phase-in: each year's taxable figure is the lower of the actual assessed value and the transitional one, so changes ripple through bills gradually.

The mechanism explains otherwise puzzling tax behavior: bills that keep rising after values plateau (prior increases still phasing in), or relief that arrives years after a market decline. For underwriting, the pipeline matters — a building's current taxes may carry embedded future increases already assessed but not yet phased in, a scheduled cost the records disclose to anyone who reads the transitional figures.
