Multiple Rental Properties, guidance on strucutre of company

[Chaz Kerns]

Have a client that has serval SFH's & Duplexes across the US. He currently has them placed in his own LLC. Can someone with more experience give some guidance on how he might better structure his company to better protect himself and/or his other assets? I am unsure which state the LLC is currently registered with; I believe it to be TX.

Current properties are in WA, TX, NC 

Or if you know someone locally willing to give some guidance that would be awesome.
