What is the best business organization for someone who owns a lot of property?

I am on track to own and manage a lot of property in the future. Therefore, I'll potentially be exposed to a lot of lawsuits and my personal ets would be at risk. What would be the best organization to protect me out of a Sole Proprietor, C-Corporation, S-Corporation, LLC, Partnership, Trust, or a Non-profit organization? Or would it be some other form of organization. Thanks!
