Investor Insight Report

Appreciation: Market value has risen +5446.9% from $16,118 (2022) to $894,053 (2025), a CAGR of 281.4% over 3 years. This is strong appreciation — well above typical inflation. Most of this growth came in a single year (2024→2025), 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 $18,297. Austin ISD is the largest single contributor, at 45.2% of the total 2025 levy.

Asset Class: O. 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 7% of market value ($58,305 land vs $835,748 improvements), about $648/SF of land. Most value sits in the improvements, so building condition, age (~5 yrs), and rent roll drive the underwriting.

Forward Outlook: Holding the +167.0% Base-scenario CAGR (Based on 2021–2026 preliminary trend, projected forward from 2026), the model projects market value near $111,246,561 by 2031, with an estimated annual tax burden around $24,860. Estimated Forward figures are model projections, not certified — see the 6-Year Projection section for the low/base/high bands.

Data sources: 2025 — TCAD Certified Appraisal Export (Appraisal: Certified — this describes property value data, not tax billing; see each row's Source column above for billing confidence). 2021–2024 values — Texas Comptroller Annual Jurisdiction Roll (AJR). 2021–2024 tax — sourced directly from Travis County Tax Office billing records (Verified); this is a comprehensive countywide billing load, not a rate-based estimate or portal receipt. See the "2021–24 billing" badge above for this specific parcel's coverage. 2026 — TCAD Preliminary Export, June 9, 2026 (Preliminary — subject to change until July 25, 2026 certification). The totals above are what's Verified for 2021–2024. This page's per-entity billing breakdown (the "2025 Tax by Entity" table) is shown for 2025 only. ! = assessed value exceeds market value in source data — known AJR data quality issue. "Value Limitation Adj" is the same homestead-cap deduction shown in the Current Values panel, computed per year as Market − Assessed. TCAD's own page also shows "Special Use Land Market" and "Special Use Exclusion" — not in Parcelytics' dataset, so they're omitted here rather than shown as $0 (see Current Values panel note).

These are illustrative scenarios, not statistical confidence ranges. ¹ Based on 2021–2026 preliminary trend, projected forward from 2026. Low: CAGR −2 pp, rates flat. Base: historical CAGR + rate trend (avg YoY change, 2021–2025). High: CAGR +2 pp, rates trend ×1.5. Actual values set by TCAD appraisal and taxing budgets each year.
Formula (per year i = 1–5 years ahead of the baseline year above): Market Value = Base Market × (1 + CAGR)i. Assessed Value = min(Base Assessed × 1.10i, Market Value) if this parcel carries a homestead cap, else = Market Value. Rate = max(0%, Current Combined Rate + Avg.

CAGR: Base = observed value CAGR over the baseline window; Low = max(−5%, Base − 2 pp); High = Base + 2 pp.
