How to protect my buy and hold properties

[Juan Llamas]

My father owns 5 residential properties. His strategy is to buy and hold. Now, all these properties are in low income areas. I want to establish a company where I can put some of these properties under a company name. The main reason is I just want to protect our other assets if we ever get sued or anything. I just wanted to get opinions from other people out there. Like how do you guys protect your investments, what is the best way? Do you setup your investments under a LLC or do you setup each individual investment under an LLC? Whats the best?
