Appreciation: Market value has risen +414.6% from $90,622 (2021) to $466,321 (2025), a CAGR of 50.6% over 4 years. This is strong appreciation — well above typical inflation. Most of this growth came in a single year (2021→2024), not a steady climb — worth checking what drove that reappraisal rather than assuming a smooth trend. Over the same span, the median Land/Vacant parcel countywide rose +487.2%, so this parcel has lagged the broader land/vacant market over the same period.
Tax Burden: The combined rate across 7 taxing entities is 2.1962% in 2025 (+0.0266% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $10,241. Del Valle ISD is the largest single contributor, at 43.2% of the total 2025 levy.
Asset Class: Land / Vacant. This is valued using the cost approach, tied more to replacement cost and physical condition than to income performance.
Value Composition: Land carries 57% of market value ($265,462 land vs $200,859 improvements), about $2/SF of land. Land and improvements both carry meaningful weight; value is balanced between the structure and its site.
Submarket Position: At $466,321, this parcel sits in the top quartile (≥75th percentile) of Land/Vacant property in Travis County — county median $85,028 (P25 $24,862 / P75 $363,420, n=35,611). Land/Vacant here is the broad TCAD category — every land/vacant 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 +50.6% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $3,614,091 by 2030, with an estimated annual tax burden around $15,976. 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.
