Frequently asked questions
NNN stands for Triple Net, meaning the tenant pays base rent plus property taxes (Net 1), building insurance (Net 2), and common area maintenance (Net 3).
CAM (Common Area Maintenance) includes shared building costs like parking lot maintenance, snow removal, security, landscaping, and exterior repairs.
Total annual rent = (Base Rent Rate + Tax Rate + Insurance Rate + CAM Rate) × Square Feet. Monthly rent = Total Annual Rent ÷ 12.
