Appreciation: Market value has risen +9034.7% from $178,694 (2021) to $16,323,134 (2025), a CAGR of 209.2% 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 1.6240% in 2025 (+0.0184% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $1,874. Lake Travis ISD is the largest single contributor, at 37.5% of the total 2025 levy.
Assessment Gap: Assessed value ($311,709) is $16,011,425 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 96% of market value ($15,718,980 land vs $604,154 improvements), about $1/SF of land. With value concentrated in the land under a ~66-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 $16,323,134, 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 +331.8% Base-scenario CAGR (Based on 2022–2025 certified trend, projected forward from 2025), the model projects market value near $24,512,238,310 by 2030, with an estimated annual tax burden around $7,052. 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.
