Appreciation: Market value has risen +24.7% from $119,790,762 (2021) to $149,405,262 (2025), a CAGR of 5.7% over 4 years. This represents moderate, steady growth. 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.
Asset Class: L2. This is valued using the cost approach, tied more to replacement cost and physical condition than to income performance.
Forward Outlook: Holding the +5.7% Base-scenario CAGR (Based on 2021–2025 certified trend, projected forward from 2025), the model projects market value near $196,921,938 by 2030, with an estimated annual tax burden around $0. 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.
