How we calculate the year-over-year change. Real estate values are heavily right-skewed: most homes move within a narrow band each year while a handful jump due to reassessments, renovations, or cap resets. An arithmetic average gets pulled by those few large moves and overstates what the typical homeowner saw. We report the median instead, which reflects the middle home in the area. This matches industry convention (Zillow, Redfin, FHFA, Case-Shiller, the Texas Comptroller) and tells you what to expect for a home like yours.
How to read these figures. These are area-wide medians, not a prediction for any single home. Appraisal districts do not apply one flat percentage across the board. Each home is valued on its own characteristics using standard appraisal methods, so your notice can move differently from the numbers here. Treat this as a starting point for whether a protest is worth a closer look, not an estimate of your own value.
