| Taxable Value | $442,633 |
Appreciation: Market value has risen +2850.9% from $15,000 (2022) to $442,633 (2025), a CAGR of 209.0% over 3 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 Land/Vacant parcel countywide rose +53.5%, so this parcel has outpaced the broader land/vacant market over the same period.
Tax Burden: The combined rate across 5 taxing entities is 2.0702% in 2025 (+0.0420% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $9,163. Del Valle ISD is the largest single contributor, at 41.4% 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 7% of market value ($31,932 land vs $410,701 improvements), about $6/SF of land. Most value sits in the improvements, so building condition, age (~3 yrs), and rent roll drive the underwriting.
Submarket Position: At $442,633, this parcel sits in the top quartile (≥75th percentile) of Land/Vacant property in Travis County — county median $84,423 (P25 $24,862 / P75 $362,804, 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 +133.1% Base-scenario CAGR (Based on 2021–2026 preliminary trend, projected forward from 2026), the model projects market value near $30,491,557 by 2031, with an estimated annual tax burden around $12,567. Estimated Forward figures are model projections, not certified — see the 6-Year Projection section for the low/base/high bands.
