Appreciation: Market value has fallen -25.4% from $181,442,400 (2022) to $135,439,829 (2025), a CAGR of -9.3% over 3 years. Growth has been relatively flat for this asset class. 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 Commercial parcel countywide rose +16.6%, so this parcel has lagged the broader commercial market over the same period.
Tax Burden: The combined rate across 5 taxing entities is 2.0465% in 2025 (+0.0647% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $2,771,756. Austin ISD is the largest single contributor, at 45.2% of the total 2025 levy.
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 ($7,823,591 land vs $127,616,238 improvements), about $60/SF of land. Most value sits in the improvements, so building condition, age (~8 yrs), and rent roll drive the underwriting.
Submarket Position: At $135,439,829, 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 -9.3% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $83,194,080 by 2030, with an estimated annual tax burden around $1,567,162. 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.
