Full-service, modified gross and NNN are not comparable rents
A $22 full-service rate and an $18 NNN rate are not $4 apart. Under a triple-net lease you pay your pro-rata share of taxes, insurance and common-area maintenance on top of base rent, and in this market that load commonly runs $5 to $8 a square foot. Ask for the operating-expense history for the last three years before you compare two buildings.
Modified gross sits between the two and means whatever the lease says it means. Read the expense-stop language. A stop set at the current year with an uncapped pass-through is a variable-rate obligation with your name on it.
