Appreciation: Market value has risen +150.3% from $648,586 (2021) to $1,623,127 (2025), a CAGR of 25.8% over 4 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 Commercial parcel countywide rose +24.1%, so this parcel has outpaced 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 $31,283. Austin ISD is the largest single contributor, at 45.2% of the total 2025 levy.
Assessment Gap: Assessed value ($1,528,618) is $94,509 below market value, suggesting potential for an upward assessment in future years.
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 56% of market value ($908,318 land vs $714,809 improvements), about $45/SF of land. Land and improvements both carry meaningful weight; value is balanced between the structure and its site.
Submarket Position: At $1,623,127, this parcel sits in the upper-middle (50th–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 +25.8% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $5,108,974 by 2030, with an estimated annual tax burden around $46,375. Estimated Forward figures are model projections, not certified — see the 6-Year Projection section for the low/base/high bands.

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.
