The Federal Reserve finally delivered a much-needed reprieve for investors by lowering the federal funds rate by 0.5% on Sept. 5. This reduction is especially welcome after an extended period of rapid interest rate hikes. For commercial property owners, however, a window may be closing on the opportunity to reduce property tax assessments based on the low interest rates that reigned during the COVID-19 pandemic.

Mortgage rates have eased slightly this year from a peak in October 2023. The average 30-year mortgage rate reached a 23-year high of 7.79% the week ending Oct. 26, 2023, marking the end of its climb from a staggering historical low of 2.66% in December 2020, according to the Freddie Mac Primary Mortgage Market Survey.

This striking contrast is crucial for commercial property owners, particularly those who bought their properties between early 2020 and the summer of 2022. That's when historically low interest rates had the 30-year mortgage rate bouncing along as low as 2.10%.
