Investor Insight Report

Appreciation: Market value has risen +67.0% from $750,000 (2021) to $1,252,633 (2025), a CAGR of 13.7% over 4 years. This is strong appreciation — well above typical inflation. Growth has been fairly evenly spread across these years rather than concentrated in one jump.

Tax Burden: The combined rate across 5 taxing entities is 1.7969% in 2025 (-0.0032% vs 2024 — rates decreased ). At the current taxable value, estimated annual taxes are $22,508. Lake Travis ISD is the largest single contributor, at 57.9% of the total 2025 levy.

Value Composition: Land carries 100% of market value ($1,252,633 land vs $0 improvements), about $22/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.

Forward Outlook: Holding the +13.7% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $2,378,357 by 2030, with an estimated annual tax burden around $33,106. 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.

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. 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 20.0%
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.

These are illustrative scenarios, not statistical confidence ranges. ¹ Based on 2021–2025 certified trend, projected forward from 2025. 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. Annual Rate Change × band multiplier × i). Est. Tax = Assessed Value × Rate ÷ 100. Band multiplier: Low = 0 (flat rates), Base = 1.0, High = 1.5. CAGR: Base = observed value CAGR over the baseline window; Low = max(−5%, Base − 2 pp); High = Base + 2 pp.
