What kind of company should I set up?

[Mike Roddie]

I Am new to Biggerpockets and somewhat to real estate.  I remodeled one home, sold it and purchased another and have remodeled that and now have a second home that I will begin remodeling soon.  In addition I purchased a house for my daughter for college and since she has now done with it I have leased it out through a Property Management agent.  I am not sure if I should set up a legal entity for the current properties (excluding the primary residence) and for future purchases/flips/investments.  Please advise.
