Hi Eric. Take the advice of the agents below but make sure that no matter what!, you are represented by an attorney. Commercial leases are a nightmare. They are long, redundant and in complete favor of the owner/landlord. You have close to -0- rights.
I've done commercial leases and would not let my client sign or initial anything without an experienced attorney to give a summary of the lease. Some leases run 50-60-70 pages. The attorney will give you a 1-2 page highlight summary of important points.
Worth the money, believe me.
GOOD LUCK to you on your new venture!!

p.s. make sure that if the LL makes you sign personally, it's only for a certain term, say 12 or 24 months. At that time you should be allowed to assign the lease to your corp or LLC with -0- personal liability. You need this in writing, too.
