Investor Insight Report

Appreciation: Market value has risen +36.0% from $566,537 (2021) to $770,580 (2025), a CAGR of 8.0% over 4 years. This represents moderate, steady growth. 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 Residential parcel countywide rose +45.8%, so this parcel has lagged the broader residential 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 $15,770. Austin ISD is the largest single contributor, at 45.2% of the total 2025 levy.

Homestead Cap History: This property had an active homestead cap as recently as 2024 ($121,381, ~15.8% of market value at the time). The cap has since reset or expired. Verified clear — 2025 Certified Historical data from AJR 2021–2024 (Partial confidence). Current status confirmed by 2025 TCAD Certified Export.

Asset Class: Single-family residential. Buyer should verify which exemptions carry and which reset at sale. This is valued using the cost approach, tied more to replacement cost and physical condition than to income performance.

Value Composition: Land carries 71% of market value ($544,611 land vs $225,969 improvements), about $76/SF of land. With value concentrated in the land under a ~89-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 $770,580, this parcel sits in the top quartile (≥75th percentile) of Residential property in Travis County — county median $479,535 (P25 $358,633 / P75 $737,055, n=318,609). Residential here is the broad TCAD category — every residential 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 +8.0% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $1,131,891 by 2030, with an estimated annual tax burden around $21,322. 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.
