  11. Gross Lease: A commercial lease that has one, all-inclusive rate which includes both base rent and the operating expenses (property taxes, insurance and CAM charges), combined into one amount. With this, tenants make one single payment to the landlord each month.
  12. Gross Rental Income (GRI): A metric that represents all income received in a commercial property from gross leases.
  13. Landlord: The owner of property that is leased or rented to another.
