Which type of lease allows for increases in rent during the lease period?

A variable lease, as identified in the question, is structured specifically to accommodate changes in rental amounts over the duration of the lease agreement. This type of lease typically includes terms that permit rent adjustments based on various factors, such as inflation, market conditions, or other specified metrics that indicate a need for change.

For instance, a variable lease may outline increases on a predetermined schedule, such as annually, or may adjust based on the Consumer Price Index (CPI). This allows landlords to ensure rental income keeps pace with economic conditions, while providing tenants with clarity on how their rental obligations may change over time.

In contrast, other lease types such as gross leases and fixed leases maintain a consistent rent amount throughout the lease period, providing stability but no allowance for increases. A renewable lease does not inherently include provisions for rent adjustments, as it typically offers the option to extend the lease under existing terms rather than changing the payment structure. Thus, the nature of a variable lease distinctly enables specified modifications in rental payments, which is its defining characteristic.
