I'm also preparing to build out my team (lawyer, CPA, contractors etc), and preparing to setup our structures and processes.  

Get a lawyer to help you.

Contract terms that are contrary to public policy are void.Always have a local lawyer review your lease, unless you are using a standard form lease from an organization that has itself had the form reviewed by a lawyer.

By this I am thinking about lawyers.  

Consult a lawyer who is experienced in real estate syndications.

In California, we used escrow companies and rarely used lawyers.

I would start off with getting a letter of intent to lease and to optionThen just put landlords name property name amount of rent which should be market rent, 3% option fee of 85,000 would be 850×3, non refundable, 12 month lease with renewable two 12 month terms, subject to the laws of Chicago Illinois and the current homeowners associationHave him sign it and you sign it and get it notarizedGo to mailbox etc. or some other place to get notarizedThen send it to your lawyer, and get first and last months rent +3% option fee now not later

My lawyer was professional enough to tell me i would be better served by contacting an attorney that specialized in RE law. 

Hopefully they can help, if not, they may point you to another wholesaler who's currently doing transactions with them, as @Mike Watkins advises, or they'll tell you which of the local lawyers have the info you need to get started.Good luck

All you need is a little understanding of the technique, a RE lawyer, and a motivated seller.
