Best LLC structure for a nomad who invests in multiple states

[Nick Thomas]

Hey BP! Need some help here. I currently have investments in 2 states (Michigan and Wisconsin) with plans to continue adding in more states to my portfolio. I live in Illinois now but have plans to move around in the next few years. 

So two main questions; should I set up a holding LLC? If so, where would be the best state to do that?

Thanks in advance and I'm newer so totally open to any and all suggestions on how to best set up a multi-state portfolio!
