I'm requesting that TCAD reduce the 2026 market value of this property from $1,568,195 to $1,450,000. That number isn't arbitrary — it's based on what comparable homes in 78757 actually sold for around the January 1 valuation date.
These are the three most relevant sales I could find. The first two closed before January 1, 2026 and are the primary evidence. The third closed shortly after and confirms the same price range. All three are 4-bed/3-bath homes with similar newer construction in the same zip code. None of them sold for anywhere near $1,568,195 — the highest among all three was $1,449,000.
| Address | Sale Date | Sale Price | Sq Ft | Why It Matters |
|---|---|---|---|---|
| 7103 Daugherty St | 12/02/2025 | $1,399,000 | 2,864 | Pre-Jan 1 comp. Similar newer construction, sold $169K below TCAD value. |
| 1812 Aggie Ln | 11/14/2025 | $1,449,000 | 2,751 | Pre-Jan 1 comp. Closed $119K below TCAD value. |
| 3102 Hunt Trl | 02/18/2026 | $1,449,000 | 3,105 | Near-date confirming sale. Still below TCAD value weeks after Jan 1. |
Comparing on a price-per-square-foot basis, the median PPSF across nearby TCAD equity comps is $470. Applied to my 3,259 sq ft home, that implies a market value of $1,531,000 — and the lowest comp PPSF of $429 implies $1,398,000. Under Texas Tax Code §41.43, I am asking that my property be treated consistently with similar nearby homes.
| Address | Sq Ft | Class | TCAD Value | $/Sq Ft | Why It Matters |
|---|---|---|---|---|---|
| 7103 Daugherty St | 2,864 | — | $1,399,000 | $488 | Similar newer construction. TCAD values it well below subject's PPSF. |
| 1812 Aggie Ln | 2,751 | — | $1,449,000 | $527 | Same bed/bath count, slightly smaller footprint. Comparable equity benchmark. |
| 3102 Hunt Trl | 3,105 | — | $1,449,000 | $467 | Near-date 2026 TCAD value with closely matching size. Strong PPSF anchor. |
Subject property: R4 class, 3,259 sq ft in 78757.
TCAD's equity-comp pool was reviewed in full. The properties below were considered and excluded from the analysis for the reasons listed. This selection is documented to demonstrate the analysis is rigorous, not selective.
Construction class R1 vs subject's R3 — different tier of finish-out (2 excluded):
Outside sqft band (subject 3,259 sq ft, ±60% = 1,304–5,214) (2 excluded):
No street number — likely vacant lot or non-residential record (1 excluded):
4 independent arguments support the requested value. Each rests on different evidence and stands on its own.
Claim: Three pre-Jan 1, 2026 sales of similar 78757 homes establish a $1,399K–$1,449K market range — none reach TCAD's $1,568,195.
The strongest evidence comes from three verified sales of similar 78757 homes. 7103 Daugherty St (4-bed, 2,864 sq ft) closed at $1,399,000 on December 2, 2025 — about $169,000 below TCAD's proposed value. 1812 Aggie Ln (4-bed, 2,751 sq ft) closed at $1,449,000 on November 14, 2025. Both pre-date the January 1, 2026 valuation date. A third sale, 3102 Hunt Trl, closed at $1,449,000 in February 2026 — confirming the same range continued post-valuation. None of these properties sold for anywhere near $1,568,195. The highest of the three was $1,449,000.
Claim: Median PPSF across nearby TCAD equity comps is $470, implying a value of $1,531,000 for the subject's 3,259 sq ft — well below the proposed $1,568,195.
Texas Tax Code §41.43 requires that my property be appraised consistently with comparable properties. The median PPSF across TCAD's own equity comps in this market area is $470. Applied to my 3,259 sq ft, that implies a value of $1,531,000. The lowest comp PPSF is $429, implying $1,398,000. My requested value of $1,450,000 sits comfortably within that range — and well below the proposed $1,568,195, which would require a PPSF of $481, above the median.
Claim: Citywide median price down 5% YoY and Travis County down 6.3% as of January 2026; close-to-list ratio of 90.8% confirms buyer-side leverage.
Broader market data confirms the case. The City of Austin median residential sale price fell 5.0% year-over-year as of January 2026, and Travis County fell 6.3%. The average close-to-list ratio is 90.8% — buyers are negotiating roughly 9% off list price. With prices declining and buyers in a stronger position, a proposed value that exceeds every relevant comparable sale by $119K–$169K can't be reconciled with what the market actually supports.
Claim: TCAD's 2025 mass-appraisal report shows a county-wide median ratio of 1.06 — TCAD valuations have run 6% above actual market sales.
TCAD's own 2025 Mass Appraisal Report shows a county-wide median sales ratio of 1.06 — meaning TCAD's assessed values have been running 6% above actual market sales. That's TCAD's own data acknowledging the modeling overshoot. Applied to a $1,568,195 proposed value, the 6% adjustment alone implies a corrected value of approximately $1,479,000 — already within striking distance of my requested $1,450,000.
Subject price-per-square-foot: $481. Comp set median: $470, mean: $472, range: $429–$511, std-dev: $24. Subject sits at the 73th percentile of the comp set.
| Scenario | PPSF | Implied Value | Rationale |
|---|---|---|---|
| Aggressive | $429 | $1,398,111 | Lowest comp PPSF × subject sqft. Strongest defensible reduction; opens negotiation room. |
| Balanced | $470 | $1,531,730 | Median comp PPSF. Most defensible at hearing — appraiser cannot easily attack the median. |
| Conservative | $491 | $1,600,169 | 75th percentile of comp PPSF. Highest probability of acceptance with smallest savings. |
| Address | Sale Date | Raw Price | Trend/mo | Months | Adjusted Price |
|---|---|---|---|---|---|
| 7103 Daugherty St | 12/02/2025 | $1,399,000 | -0.40% | 1 | $1,393,404 |
| 1812 Aggie Ln | 11/14/2025 | $1,449,000 | -0.40% | 2 | $1,437,432 |
It's not just my comps. The overall Austin market was softer heading into 2026. Median prices were down year-over-year and homes were closing at roughly 91 cents on the dollar versus list price. When the broader market is declining and buyers are negotiating 9% off list price on average, a proposed value that exceeds every relevant comp by $119K–$169K doesn't hold up.

This protest invokes both the market-value standard under §23.01 and the equal-and-uniform standard under §41.43(b)(3). The market sales section establishes that comparable homes near the January 1 valuation date sold for less than the proposed value. The equity comps section establishes that similarly-sized, similarly-classed properties in the same zip code carry lower TCAD values on a price-per-square-foot basis. Either standard, considered alone, supports a reduction; together they make a strong case.
Tex. Tax Code §41.41(a)(1) — Right to Protest Determination of Appraised Value
A property owner is entitled to protest before the appraisal review board the determination of the appraised value of the owner's property.
Tex. Tax Code §41.41(a)(2) — Right to Protest Unequal Appraisal
A property owner is entitled to protest unequal appraisal of the owner's property.
Tex. Tax Code §23.01(a) — Market Value as of January 1
Except as otherwise provided by this chapter, all taxable property is appraised at its market value as of January 1.
Tex. Tax Code §41.43(b)(3) — Equal-and-Uniform Standard
A protest on the ground of unequal appraisal shall be determined in favor of the protesting party unless the appraisal district establishes that the appraised value of the property is equal to or less than the median appraised value of a reasonable number of comparable properties appropriately adjusted.
The best comparable sales — all in 78757, all similar construction, all near the valuation date — landed between $1,399,000 and $1,449,000. The broader market data confirms pricing was soft. A requested value of $1,450,000 is at the top of that comp range, which I think is fair to both sides.
Requested market value: $1,450,000

If TCAD invites you to an informal meeting, bring this. Q&A, cheat sheet, what NOT to say — all tailored to your case.
| If TCAD says… | Respond with… |
|---|---|
| Your comps are smaller homes — they don't compare apples-to-apples. | I normalized on price-per-square-foot, which controls for size. The PPSF gap holds across all three comps regardless of footprint. |
| Sales after January 1 don't count for valuation. | Two of my three comps closed in November and December 2025 — pre-Jan 1. I included the post-Jan 1 sale only as a trend confirmation. |
| Those homes are in a different market area or class. | All three comps are in 78757, all are 4-bed/3-bath newer construction. Construction class and zip-code match are documented in the equity comps table. |
| Median sale prices in your zip have actually held up year-over-year. | Citywide median is down 5% YoY and Travis County is down 6.3%. The MLS close-to-list ratio is 90.8% — buyers are negotiating real discounts. |
| We use mass-appraisal modeling, not individual sales. | Tex. Tax Code §23.01 requires market value as of January 1 — your model has to be reconcilable with actual sales near that date. Mine are. |
