Which of the following best describes a gross lease?

A gross lease is characterized by a rental agreement where the tenant pays a fixed amount for the rent, and the landlord is responsible for covering all operating expenses associated with the property, which typically includes utilities, maintenance, property taxes, and insurance. This kind of arrangement provides tenants with predictability regarding their costs since they don't have to worry about fluctuating expenses that might arise from utilities or upkeep.

The flat rental fee aspect highlighted makes option B the most accurate description of a gross lease because it encapsulates the key feature of this lease type: the tenant pays a set amount while the landlord manages the associated costs.

In contrast, the first choice relates more to a net lease arrangement where the tenant is responsible for paying additional operating expenses separately. The third option points toward a variable lease that changes with market conditions, which is not a defining feature of a gross lease. Lastly, the fourth option references contingent leasing agreements, which do not pertain to the fundamental nature of how gross leases are structured.
