What unequal appraisal means: Under Texas Tax Code §41.43(b)(3), your home is unequally appraised if its appraised value is greater than the median appraised value of a reasonable number of comparable properties, appropriately adjusted. The median above is the starting point — a strong evidence pack uses comps from your own subdivision and street, adjusted for size, age, and condition.
2027 protest deadline
Monday, May 17, 2027. May 15, 2027 is a Saturday, so the deadline moves to the next business day under §1.06. This date is derived from statute — HCAD has not published its 2027 notice yet; confirm it against your notice when it arrives (~April 2027).
Illustrative estimate only — not legal, tax, or appraisal advice. No outcome is guaranteed, and the Appraisal Review Board can raise your value. Verify all figures against your HCAD notice.
