Investor Insight Report

Tax Burden: The combined rate across 6 taxing entities is 1.8841% in 2025 (+0.0525% vs 2024 — rates increased ). At the current taxable value, estimated annual taxes are $1,421. Leander ISD is the largest single contributor, at 55.8% of the total 2025 levy.

Homestead Cap History: This property's 2026 preliminary assessed value is $4,067,757 (~97.6%) below market value, consistent with an active homestead cap — a homestead exemption is on file for this year, but no 2021–2024 AJR-recorded cap-loss figure exists for this parcel to confirm the exact historical amount, so this is an estimate from the certified/preliminary values themselves. Estimated from 2026 certified/preliminary values (Partial confidence) — AJR 2021–2024 has no record for this parcel.

Asset Class: Single-family residential. Buyer should verify which exemptions carry and which reset at sale. This is valued using the cost approach, tied more to replacement cost and physical condition than to income performance.

Value Composition: Land carries 88% of market value ($7,431,295 land vs $978,198 improvements), about $1/SF of land. With value concentrated in the land under a ~48-year-old structure, this reads as a land-dominated asset — the classic higher-and-best-use / redevelopment signal. Underwrite the dirt, not the building.

Submarket Position: At $8,409,493, this parcel sits in the top quartile (≥75th percentile) of Residential property in Travis County — county median $479,535 (P25 $358,633 / P75 $737,055, n=318,609). Residential here is the broad TCAD category — every residential 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.

No delinquent taxes on record.

Large Value Jump

Market value changed by 303% in 2024, flagged as unusually large. Verify against comparable sales before using this value in underwriting.

!
Cap Step-Up Exposure Verified

This parcel carries a real, materially-sized homestead cap per 2025 Certified data — assessed value is meaningfully below market value. A buyer loses this benefit at purchase and the assessed value resets to full market, increasing the annual tax bill. Factor this into acquisition underwriting. Cap activity consistent with AJR records back to 2026.

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.
