I would just suggest that if you need an operating agreement, that you should reach out to an attorney.Regarding the Florida LLC, just make sure you are compliant with certain words not being eligible to be used in the entity name.I.E.

I plan to speak with an attorney before I do any marketing but I would appreciate any guidance from MD investors on marketing in the state (mainly looking into direct mail and cold calling) while being completely compliant with local and federal laws.I have heard of other investors (not in MD) having success with marketing to tax delinquent lists. 

At any one time we have 20-30 notes on the books, with an average loan size of $1.4 million.If I dealt in residential owner occupied I’d use a note servicer to make sure I stayed compliant with the SAFE Act and the CFPB
