How this is calculated
For each Texas ZIP code, we compute the average market value per square foot from HCAD public records. A property is "flagged as overassessed" if its market value is more than 10% abovewhat the ZIP's typical dollar-per-square-foot would predict for that home's size.
Annual overpayment $ uses Harris County's average effective tax rate of 2.15%. Real savings vary by ISD, city, and MUD. An over-assessment carries into next year until you correct it; the next protest window is April-May 2027. Reserve a $49 protest kit and I'll pull your fresh 2027 comps the moment HCAD publishes them.
