A triple net lease is a commercial real estate lease agreement in which the tenant is responsible for paying all operating expenses associated with the property. This includes property taxes, insurance, and maintenance costs, in addition to the rent. Essentially, the tenant assumes all of the financial risk associated with owning the property, while the landlord collects a fixed rental income. Triple net leases are commonly used in commercial real estate transactions, particularly for properties with long-term tenants such as retail stores, office buildings, and industrial warehouses. Because the tenant is responsible for all expenses associated with the property, the landlord can be more hands-off and simply collect rental income each month.
