Investor Insight Report

Appreciation: Market value has fallen -17.6% from $5,260,349 (2021) to $4,336,863 (2025), a CAGR of -4.7% over 4 years. Growth has been relatively flat for this asset class. 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 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 $56,523. Austin ISD is the largest single contributor, at 50.2% 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 55% of market value ($2,374,000 land vs $1,962,863 improvements), about $100/SF of land. Land and improvements both carry meaningful weight; value is balanced between the structure and its site.

Submarket Position: At $4,336,863, 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 -4.7% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $3,407,039 by 2030, with an estimated annual tax burden around $64,180. 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.
