LLC & Series feedback

[Joe E.]

Wanted to get some informal BP feedback on legal entities, and realize this is not legal advise.

I wanted to learn more about setting up legal entities for REI. After finding a mention of a law firm which specializes in REI law here on BP, reviewed its site & scheduled an appointment. The appointment went well, learned a fair bit, liked the overall concept which was proposed and quoted: a solution incorporating traditional LLCs, series LLCs & trusts in the $7k range.

My concerns: Series LLC have been around ~ 20 years now, and can only be formed by some US states.  As I intend to purchase properties across various states (some of which are where Series cannot be formed), I am wondering about the legal uncertainty surrounding Series as well as the potential difficulties of using it across state lines.

Thanks in advance!
