| Taxable Value | $774,577 |
Appreciation: Market value has risen +560.7% from $146,538 (2023) to $968,221 (2025), a CAGR of 157.0% over 2 years. This is strong appreciation — well above typical inflation. Growth has been fairly evenly spread across these years rather than concentrated in one jump. Over the same span, the median Land/Vacant parcel countywide rose +18.9%, so this parcel has outpaced the broader land/vacant market over the same period.
Tax Burden: The combined rate across 6 taxing entities is 2.5114% in 2025 (+0.0586% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $19,453. Leander ISD is the largest single contributor, at 41.3% 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 38% of market value ($365,654 land vs $602,567 improvements), about $45/SF of land. Most value sits in the improvements, so building condition, age (~5 yrs), and rent roll drive the underwriting.
Submarket Position: At $968,221, 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 +157.1% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $108,651,342 by 2030, with an estimated annual tax burden around $33,817. 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.
