Investor Insight Report

Appreciation: Market value has risen +4.1% from $631,727 (2021) to $657,394 (2025), a CAGR of 1.0% over 4 years. Growth has been relatively flat for this asset class. Most of this growth came in a single year (2021→2022), not a steady climb — worth checking what drove that reappraisal rather than assuming a smooth trend. Over the same span, the median Multi-Family parcel countywide rose +19.0%, so this parcel has lagged the broader multi-family market over the same period.

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 $13,453. Austin ISD is the largest single contributor, at 45.2% of the total 2025 levy.

Asset Class: Multi-family residential. 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 60% of market value ($393,816 land vs $263,578 improvements), about $49/SF of land. Land and improvements both carry meaningful weight; value is balanced between the structure and its site.

Submarket Position: At $657,394, this parcel sits in the upper-middle (50th–75th percentile) of Multi-Family property in Travis County — county median $519,086 (P25 $438,150 / P75 $747,031, n=12,570). Multi-Family here is the broad TCAD category — every multi-family 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 +6.3% Base-scenario CAGR (Based on 2021–2026 preliminary trend, projected forward from 2026), the model projects market value near $1,164,828 by 2031, with an estimated annual tax burden around $21,942. 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).
Value Trend
Market Value vs. Taxable Value gap up to 8.0%
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.
