Assessment Environment: The 2025 reappraisal year uses market data from July 1, 2022 through June 30, 2024, with significant value impacts from interest rate changes.
Strategic Considerations: Office and apartment properties experiencing value declines create appeal opportunities, while hotels and retail properties maintain stronger valuations.
