| Taxable Value | $186,620 |
Appreciation: Market value has risen +22.8% from $298,530 (2021) to $366,489 (2025), a CAGR of 5.3% over 4 years. This represents moderate, steady growth. Growth has been fairly evenly spread across these years rather than concentrated in one jump. Over the same span, the median Multi-Family parcel countywide rose +37.9%, so this parcel has lagged the broader multi-family 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 $3,819. Austin ISD is the largest single contributor, at 44.1% of the total 2025 levy.
Asset Class: Multi-family residential. This is valued using the cost approach, tied more to replacement cost and physical condition than to income performance.
Value Composition: Land carries 70% of market value ($255,947 land vs $110,542 improvements), about $35/SF of land. Land and improvements both carry meaningful weight; value is balanced between the structure and its site.
Submarket Position: At $366,489, this parcel sits in the bottom quartile (<25th 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.
Forward Outlook: Holding the +5.3% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $473,590 by 2030, with an estimated annual tax burden around $8,921. 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.
