Reappraisal Cadence

West Virginia assessors have a statutory duty to keep the property roll current — to revisit values on the mandated reappraisal cycle so appraisals track the market over time. This page measures one concrete, assessor-attributable duty: the share of each county's residential roll that has drifted out of date — parcels where at least 20% of market movement has not yet been captured in the appraised value. This is distinct from the market-driven level of assessment (how high or low values sit overall): a roll can be at any level and still be stale if it simply hasn't been refreshed.
