Investor Insight Report

Appreciation: Market value has risen +451.8% from $271,814 (2021) to $1,500,000 (2025), a CAGR of 53.3% over 4 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. Over the same span, the median Agricultural parcel countywide rose +96.0%, so this parcel has outpaced the broader agricultural market over the same period.

Tax Burden: The combined rate across 5 taxing entities is 1.6225% in 2025 (+0.0183% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $21. Austin ISD is the largest single contributor, at 57.0% of the total 2025 levy.

Assessment Gap: Assessed value ($1,319) is $1,498,681 below market value, suggesting potential for an upward assessment in future years.

Asset Class: Agricultural. Agricultural valuation may be subject to rollback taxes if land use changes.

Value Composition: Land carries 189% of market value ($2,831,400 land vs $0 improvements), about $5/SF of land. With value concentrated in the land, this reads as a land-dominated asset — the classic higher-and-best-use / redevelopment signal. Underwrite the dirt, not the building.

Submarket Position: At $1,500,000, this parcel sits in the top quartile (≥75th percentile) of Agricultural property in Travis County — county median $561,432 (P25 $179,824 / P75 $1,355,511, n=7,602). Agricultural here is the broad TCAD category — every agricultural 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 +53.3% Base-scenario CAGR (Based on 2022–2026 preliminary trend, projected forward from 2026), the model projects market value near $12,687,193 by 2031, with an estimated annual tax burden around $187,892. 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.

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).
Value Trend
Market Value vs. Taxable Value gap up to 100.0%
The gap between these two lines is a homestead cap or exemption reducing what's actually taxed below the certified market value -- not a data error. Same market_value / taxable_value figures as the Value History table above.

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.
