Source: Full Harris County A1 residential serving index (official HCAD roll). Aggregated 2026-06-25. Public records only — no owner-name lookup. “Over-assessed” here means appraised value per square foot at least 12% above the neighborhood comparable median — an equal-and-uniform uniformity screen, not an appraisal and not a determination that any assessment is incorrect (it does not reflect exemptions, the homestead cap, condition, or quality). This site is not affiliated with HCAD or any taxing authority. Figures are ZIP-level aggregates, not a prediction for any individual property.
