| Taxable Value | $687,169 |
Appreciation: Market value has risen +46.5% from $586,165 (2024) to $858,961 (2025), a CAGR of 46.5% over 1 year. 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 +28.8%, 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 $17,258. Leander ISD is the largest single contributor, at 40.8% 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 43% of market value ($365,654 land vs $493,307 improvements), about $45/SF of land. Most value sits in the improvements, so building condition, age (~4 yrs), and rent roll drive the underwriting.
Submarket Position: At $858,961, 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 +46.5% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $5,804,185 by 2030, with an estimated annual tax burden around $30,001. 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.
