Should I use an LLC or Umbrella Insurance?

[Efren Barriga]

Hey guys, My name is Efren and I am a beginner to the landlord business. I have a property about 1,700+sqft, was not using about 250+sqft. I turned the 250+sqft into a studio. Studio is equipped with a brand new bathroom, kitchenette, flooring and much more. I am planning to rent both my 4brd and 2bd house along with the studio in the near future. For now i wanted to get experience and start small. I will be looking to rent the studio by Feb 2017. Should I get an LLC now for the property or would an umbrella insurance be sufficient?
