Should I Create a Corporate for Rental Units

[Huy Le]

I have 2 rental units with the cash flow of 36k a year. I am thinking to add some more rental unit. My question is, should I keep it as a schedule C on my tax report or create a legel business such as Corp. or LLC ? And if I create an LLC, what is the true benefits? Additional question, Do I have to change the name on the deed of my rental units to the business name as the owner?
