Frequently Asked Questions

What factors should I compare when evaluating two lease proposals?

Focus on total occupancy cost, not just base rent. Key factors: effective rent after concessions (TI allowance + free rent), NNN/operating expense pass-throughs, annual escalation rate, lease term, and option provisions. A lease with lower base rent but higher NNN charges or fewer concessions may cost more over the full term.

What is the best way to compare a gross lease vs NNN lease?

Convert both to effective rent per square foot per year, inclusive of all occupancy costs. For a gross lease, the base rent includes operating expenses — enter NNN charges as $0. For a NNN lease, add base rent plus all pass-throughs. The 5-year total cost comparison in this tool accounts for escalations and concessions.
