Master lease option help on commercial office.

[John Menton]

What's up BP, I've been talking with a property owner that may be open to doing a master lease with option to buy because I currently do not have the cash needed for traditional financing and he is looking to unload some properties due to an illness. Selling price is 1M, NOI is 120/k There's a lot of great info on here about MLO's, and I hope this isn't a stupid question but who helps write these? Real estate attorney? Commercial agent? I'm looking for someone in Massachusetts that is familiar with master lease options, thanks!
