In a net or modified gross lease, what is the difference between an expense stop and rent escalations?

• A. Expense stop sets a threshold for tenant responsibility for operating costs; rent escalations increase base rent over time
• B. Expense stop deals with rent only; escalations deal with CAM only
• C. Rent escalations cap at a fixed rate and never increase
• D. Expense stop applies only to taxes

Answer: (A)

In a net or modified gross lease, two mechanisms control how tenant costs change over time: expense stops and rent escalations. An expense stop sets a threshold for operating costs that the tenant must pay; the landlord covers operating expenses up to that stop, and any costs above it are charged to the tenant. Rent escalations, meanwhile, are increases to the base rent itself at set intervals, designed to rise over the term to reflect growing costs or market conditions. So the expense stop defines what portion of operating costs the tenant is responsible for beyond a fixed level, while rent escalations push the base rent higher as time goes on. The other options mix up which costs are involved or incorrectly claim escalations never increase.
