Appreciation: Market value has risen +79.7% from $63,337,083 (2022) to $113,844,828 (2025), a CAGR of 21.6% over 3 years. This is strong appreciation — well above typical inflation. Most of this growth came in a single year (2022→2023), not a steady climb — worth checking what drove that reappraisal rather than assuming a smooth trend. Over the same span, the median Commercial parcel countywide rose +16.6%, so this parcel has outpaced the broader commercial market over the same period.
Asset Class: Commercial. No homestead exemptions apply — full market value is taxable. This is valued using the income approach, so changes in rent roll or occupancy move the appraisal more directly than they would for a cost-approach property.
Value Composition: Land carries 6% of market value ($6,518,449 land vs $107,326,379 improvements), about $45/SF of land. Most value sits in the improvements, so building condition, age (~6 yrs), and rent roll drive the underwriting.
Submarket Position: At $113,844,828, this parcel sits in the top quartile (≥75th percentile) of Commercial property in Travis County — county median $1,417,484 (P25 $649,268 / P75 $3,347,260, n=13,608). Commercial here is the broad TCAD category — every commercial 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 +21.6% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $302,509,291 by 2030, with an estimated annual tax burden around $0. Estimated Forward figures are model projections, not certified — see the 6-Year Projection section for the low/base/high bands.
