Investor Insight Report

Appreciation: Market value has risen +47.9% from $545,356 (2022) to $806,640 (2025), a CAGR of 13.9% over 3 years. This is strong appreciation — well above typical inflation. Most of this growth came in a single year (2022→2023), not a steady climb — worth checking what drove that reappraisal rather than assuming a smooth trend.

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 $10,141. Austin ISD is the largest single contributor, at 38.1% of the total 2025 levy.

Assessment Gap: Assessed value ($798,456) is $8,184 below market value, suggesting potential for an upward assessment in future years.

Asset Class: O. This is valued using the cost approach, tied more to replacement cost and physical condition than to income performance.

Value Composition: Land carries 8% of market value ($63,697 land vs $742,943 improvements), about $100/SF of land. Most value sits in the improvements, so building condition, age (~7 yrs), and rent roll drive the underwriting.

Forward Outlook: Holding the +13.9% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $1,548,861 by 2030, with an estimated annual tax burden around $24,223. 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.
