Change in roll home value, ranked highest first across Williamson County, Texas
(14 ranked in total).
How the headline figure is computed
Thrall against Jarrell, the highest and lowest of the 14 units compared. Every unit is named individually in the table below and each figure is that unit's own; none of them is a figure for the market as a whole. The median across the 14 is -4.1%.
Universe
Cities within Williamson County with at least 500 qualifying parcels on both rolls. Parcels carrying an agricultural valuation are excluded, because an agricultural appraisal follows a different statutory rule and its change is not a housing-market observation. Rows for cities that cross the county line are labelled as the Williamson County portion.
