| Taxable Value | $101,499 |
Appreciation: Market value has risen +1534.4% from $97,993 (2021) to $1,601,584 (2025), a CAGR of 101.1% over 4 years. This is strong appreciation — well above typical inflation. Most of this growth came in a single year (2024→2025), not a steady climb — worth checking what drove that reappraisal rather than assuming a smooth trend. Over the same span, the median Agricultural parcel countywide rose +479.4%, so this parcel has outpaced the broader agricultural market over the same period.
Tax Burden: The combined rate across 4 taxing entities is 0.6938% in 2025 (+0.0504% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $704. Travis County is the largest single contributor, at 50.6% of the total 2025 levy.
Assessment Gap: Assessed value ($126,041) is $1,475,543 below market value, suggesting potential for an upward assessment in future years.
Asset Class: Agricultural. Agricultural valuation may be subject to rollback taxes if land use changes.
Value Composition: Land carries 94% of market value ($1,504,500 land vs $97,084 improvements), about $1/SF of land. With value concentrated in the land under a ~101-year-old structure, this reads as a land-dominated asset — the classic higher-and-best-use / redevelopment signal. Underwrite the dirt, not the building.
Submarket Position: At $1,601,584, this parcel sits in the top quartile (≥75th percentile) of Agricultural property in Travis County — county median $597,708 (P25 $207,536 / P75 $1,442,275, n=7,602). Agricultural here is the broad TCAD category — every agricultural property countywide, any size or use — not a use-code-specific peer group. See the Peer Set and the Where This Property Stands benchmark below, which narrows to this property's actual use code, for parcel-level comparables.
Forward Outlook: Holding the +146.8% Base-scenario CAGR (Based on 2022–2025 certified trend, projected forward from 2025), the model projects market value near $146,577,572 by 2030, with an estimated annual tax burden around $1,471. Estimated Forward figures are model projections, not certified — see the 6-Year Projection section for the low/base/high bands.
No delinquent taxes on record.

Estimate only. The appraisal district sets value as of Jan 1 (not at sale price). A sale is strong evidence of market value and is typically reflected in the next Jan 1 valuation. Taxing units set rates annually. Modeled from government data — not a legal or tax opinion.
