Investor Insight Report

Appreciation: Market value has risen +116.3% from $573,920 (2021) to $1,241,313 (2025), a CAGR of 21.3% 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 +479.4%, so this parcel has lagged the broader agricultural market over the same period.

Tax Burden: The combined rate across 5 taxing entities is 1.5815% in 2025 (+0.0243% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $5,618. Travis County is the largest single contributor, at 47.9% of the total 2025 levy.

Assessment Gap: Assessed value ($622,768) is $618,545 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 53% of market value ($659,913 land vs $581,400 improvements), about $1/SF of land. Land and improvements both carry meaningful weight; value is balanced between the structure and its site.

Submarket Position: At $1,241,313, this parcel sits in the upper-middle (50th–75th percentile) of Agricultural property in Travis County — county median $597,708 (P25 $207,536 / P75 $1,442,275, 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 +25.7% Base-scenario CAGR (Based on 2022–2025 certified trend, projected forward from 2025), the model projects market value near $3,895,611 by 2030, with an estimated annual tax burden around $14,367. 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.
