Frequently Asked Questions
What is a NNN (triple net) lease?
A NNN lease means the tenant pays base rent plus three additional costs: property taxes, building insurance, and common area maintenance (CAM). Total occupancy cost = base rent + NNN charges. NNN leases are common for retail and commercial properties.
What is the difference between gross and NNN leases?
In a gross lease, the landlord pays all operating expenses and the rent is all-inclusive. In a NNN lease, the tenant pays base rent plus property tax, insurance, and CAM separately. NNN base rents are lower, but total costs may be similar. Modified gross splits expenses between landlord and tenant.
How is commercial rent calculated?
Commercial rent is quoted as price per square foot per year. If a 2,000 sq ft space is $25/sq ft/year, annual rent = $50,000 ($4,167/month). Always clarify whether the rate includes NNN charges or is the base only.
