What this means for a protest here
Highland Hills' evidence base comes from 219 parcels that ran through the same address-level comparison a homeowner here would use and came back with an actual case — out of 540 evaluated parcels in the neighborhood, that's 41% with a case at all. The outcomes among those 219 aren't uniform: the middle half landed between a 2% and a 7% reduction, the median came in at 4%, and the top of the range reached as high as 57%. Where any one property falls in that range comes down to its own value and comparables, not this page's averages.
The comparable homes behind those numbers range from $32 to $507 in appraised value per square foot — a gap wide enough that two houses of similar size can carry very different tax bills, which is why size matters as much as location when building a case. The properties in this pool have a median living area of 1,400 square feet, and comparisons get normalized to that size rather than treated as raw price-per-house. None of this means every property here has a case, or that any case results in the same reduction — the 41% and the reduction spread above describe this neighborhood's evaluated parcels, not a promise about any single address.
How filing a protest actually works
Your deadline to file a written protest is whichever comes later: May 15, or the 30th day after your appraisal district delivers your notice of appraised value. There's no single date that applies to everyone — it depends on when your own notice arrives, not a date any page can print in advance.
A protest based on unequal appraisal compares your property against similar, nearby homes in this same neighborhood. LoneStarLower prepares that comparison and the supporting materials; it does not file the protest, negotiate with the appraisal district, or represent you at a hearing. You file it, using Form 50-132 or an equivalent written notice, with your county's appraisal district office — not the Texas Comptroller, which doesn't handle individual protests. You attend the hearing and present the evidence yourself.

Why does square footage matter so much for a Highland Hills protest?
