@Robert ShoffnerBoth the buyer and the seller will sign a document stating that there are no side agreements in regards to the transaction. 

If not, it may be helpful for you to talk to a corporate lawyer in the state where you plan to form the entity to make sure you get the right documentation and understand the limitations of entities under applicable state law (particularly as the limitations relate to limited liability).

It may also require certain language in the organizational documents, so it really takes an attorney who specializes in these types of structures, so it may be easier to just make it a single member LLC.Now every State is different, but in most cases as long as it is a "bonafide" business interest, there is usually not significantly more protection with a multi member LLC over a single member.Hope this helps, good luck!
