What this means for a protest here

Castle Hills' median home comes in at 3,063 square feet of living area — a fairly large footprint, which matters because the comparison math used to test for a protest case is largely size-driven. This page combines two separate Denton County geo-codes, SL9450A and SL9734A, into a single Castle Hills profile, since the county tracks them as distinct records covering the same community. Across the 733 parcels here with enough neighboring data to run a full comparison, 51% came back with a documented case — a real gap between the county's valuation and what comparably sized homes nearby support, calculated the same way the county's own comp-based math works, not a market-average guess.

For the 377 parcels where that gap showed up, the size of it varied a lot: half landed between 1% and 5% of the appraised value, the smallest amounts were just above zero, and the largest reached 27%. That range lines up with how unevenly this neighborhood is priced per square foot to begin with — comparable homes here run from about $2 per square foot at the low end to $355 at the high end, a spread wide enough to reflect real differences in age, lot, and finish-out, but also wide enough that county valuations can drift out of line with a specific home's actual comparables. None of this tells you what your own address would show; it tells you the kind of gap this neighborhood's data has actually produced when run through the comparison, which is the evidence a protest packet is built to lay out for you to bring to a hearing yourself.

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.
