Investor Insight Report

Appreciation: Market value has risen +1717.4% from $4,991,707 (2021) to $90,720,000 (2025), a CAGR of 106.5% over 4 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. Over the same span, the median Multi-Family parcel countywide rose +19.0%, so this parcel has outpaced the broader multi-family market over the same period.

Tax Burden: The combined rate across 7 taxing entities is 1.8536% in 2025 (+0.0359% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $1,681,616. Round Rock ISD is the largest single contributor, at 48.2% 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 5% of market value ($4,165,425 land vs $86,554,575 improvements), about $8/SF of land. Most value sits in the improvements, so building condition, age (~2 yrs), and rent roll drive the underwriting.

Submarket Position: At $90,720,000, this parcel sits in the top quartile (≥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 +85.0% Base-scenario CAGR (Based on 2021–2026 preliminary trend, projected forward from 2026), the model projects market value near $2,347,551,441 by 2031, with an estimated annual tax burden around $2,525,656. Estimated Forward figures are model projections, not certified — see the 6-Year Projection section for the low/base/high bands.
