Which type of lease maintains a specific rent level throughout its duration?

A flat rental lease is structured to maintain a specific rent level throughout its duration, meaning the tenant pays a predetermined amount of rent consistently, without increases or decreases over the lease term. This type of lease provides predictability for both the tenant and the landlord, making it easier for tenants to budget their expenses and for landlords to anticipate rental income.

In contrast, excess rent and overage rent generally involve rental amounts that can vary based on performance metrics or additional charges tied to property income, which do not provide the same level of stability in rent payments. Effective rent, on the other hand, calculates the average rental cost over time, accounting for concessions or innovations, further illustrating that it is not fixed in the same manner as a flat rental lease. This clarity on structures aids in understanding how each type functions within rental agreements.
