... as I own my RE portfolio via my single member LLC is there a process that I can setup wherein the event of my death that LLC passes to my designated individual along with the assets owned by my LLC? 

Yes, I've closed on 4, rehabbed them, and they are all rented with tenants in place :)OK, and for these deals, I assume you use your own funds to acquire and rehab.With private money, you're now substituting some individual's funds for your own.However, unlike when it was just your money, you'll need to proceed with extreme caution to make certain your lenders are well protected if/when things don't go as planned.Private lending is its own whole profession.
