Appreciation: Market value has risen +207.2% from $99,000 (2021) to $304,171 (2025), a CAGR of 32.4% over 4 years. This is strong appreciation — well above typical inflation. Most of this growth came in a single year (2021→2022), 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 +283.7%, so this parcel has lagged the broader land/vacant market over the same period.
Tax Burden: The combined rate across 5 taxing entities is 1.7936% in 2025 (+0.0282% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $5,087. Lake Travis ISD is the largest single contributor, at 58.0% of the total 2025 levy.
Assessment Gap: Assessed value ($283,638) is $20,533 below market value, suggesting potential for an upward assessment in future years.
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 100% of market value ($304,171 land vs $0 improvements), about $17/SF of land. With value concentrated in the land, this reads as a land-dominated asset — the classic higher-and-best-use / redevelopment signal. Underwrite the dirt, not the building.
Submarket Position: At $304,171, this parcel sits in the upper-middle (50th–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 +24.7% Base-scenario CAGR (Based on 2021–2026 preliminary trend, projected forward from 2026), the model projects market value near $898,944 by 2031, with an estimated annual tax burden around $14,324. 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.
