ROBUST dimension

Stability

Pressure for reassessment or structural change. Stability asks how much evidence suggests that the current assessment relationship may face a broader reset.

What Stability measures

The current property score uses the inverse of Watchdog's governed revaluation-pressure score. More revaluation pressure means less Stability under the current model.

Current governed marker: Watchdog revaluation risk uses available-input normalization built from 45% low published Chapter 123 ratio, 25% positive published-to-verified-sale ratio drift and 30% residential COD pressure when COD is available. Missing COD is dropped and the remaining weights are renormalized.

Why it matters

A low current assessment may feel favorable today while also carrying uncertainty if the broader municipal system appears ready for a reset. Stability gives the Watchdog Score a way to represent that structural pressure without pretending to predict the date of a revaluation.

Illustrative example
Current conditionLow ratio + widening drift
ROBUST effectStability becomes more pressured

This is a screening interpretation, not a forecast that a municipality will order or complete a revaluation on a specific date.

Evidence behind Stability

  • Official Chapter 123 ratio context.
  • Watchdog verified-sale assessment-ratio drift.
  • Residential COD when available.
  • Historical assessment and market relationships used for supporting explanation.

What it does not mean

Stability is not a government-action prediction. It does not say that a revaluation is scheduled, required or guaranteed. It measures evidence of pressure under the current model.

Research direction

Future versions should test how well Stability identifies actual assessment-reset environments, whether additional official revaluation events improve calibration and how much weight the property score should give this dimension.
