Appreciation: Market value has fallen -0.9% from $2,431,133 (2021) to $2,410,261 (2025), a CAGR of -0.2% over 4 years. Growth has been relatively flat for this asset class. Most of this growth came in a single year (2025→2026), 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 +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 2.0144% in 2025 (+0.0900% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $48,552. Round Rock ISD is the largest single contributor, at 44.3% 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 89% of market value ($2,147,970 land vs $262,291 improvements), about $30/SF of land. With value concentrated in the land under a ~50-year-old structure, this reads as a land-dominated asset — the classic higher-and-best-use / redevelopment signal. Underwrite the dirt, not the building.
Submarket Position: At $2,410,261, 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 -0.2% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $2,384,423 by 2030, with an estimated annual tax burden around $41,051. 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.
