Leases vary by building, by market, and by market circumstances. In most major metros, when dealing with larger buildings, the lease document is sophisticated and complex, addressing a broad range of variables that will have a material impact on the occupier’s experience at the building, as well as its cost of occupancy. If you’ve done a good job negotiating the letter of intent, you should begin the lease negotiation phase from a position of relative strength. However, even when the letter of intent is fully maximized, there’s still a lot to negotiate in the lease.
