In many cases rent resets and structure are determined using the Consumer Price Index also known as a CPI. An increase in the CPI over a given period (usually in the 25th, 33rd, or 49th year of the lease term) and the loss in the property value is compensated by a proportionate percentage increase in rent that is calculated based on the change to the CPI, thereby protecting the lessor from inflationary pressures. Using the same rent floor and ceiling discussed above can alleviate the lessee’s risk.
