Residents on a block start comparing notes after reassessment notices go out, and it turns out two nearly identical rowhomes — same square footage, same block, similar condition — came back with assessments tens of thousands of dollars apart. Nobody on the block can tell whether that's a fluke or a broader pattern along the street.
A block association member enters each address along the street into TaxAssessmentIQ, pulling the current assessment and comparable sales for every property.
Laid side by side, most of the block's assessments track comparable sales closely, but a handful — including the two neighbors who first noticed the gap — come back visibly out of step with the rest.
An individual assessment can look reasonable in isolation and still be inconsistent with the house three doors down.
Rather than a blanket claim that "the block is over-assessed," the association can point specific households to their own comparable-sales gap and a ready-to-file appeal packet, while leaving the accurately assessed homes alone.
Block captains and civic or neighborhood associations checking assessment consistency across a street, and residents who suspect a gap but don't yet have the comparable-sales evidence to back it up.
