Investor Insight Report

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.
