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 $1,480,573. Round Rock ISD is the largest single contributor, at 44.3% of the total 2025 levy.
Asset Class: Multi-family residential. 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 9% of market value ($6,700,399 land vs $66,799,601 improvements), about $10/SF of land. Most value sits in the improvements, so building condition, age (~2 yrs), and rent roll drive the underwriting.
Submarket Position: At $73,500,000, this parcel sits in the top quartile (≥75th percentile) of Multi-Family property in Travis County — county median $519,778 (P25 $438,669 / P75 $749,859, n=12,584). Multi-Family here is the broad TCAD category — every multi-family 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.
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.
