Congratulations on getting accepted! There is a Facebook group that you might want to join if you are looking for people to room with. Most people that rent live fairly close to school so South Pasadena, Alhambra, etc. Some people come in from the Westside of LA. Others commute from further away. If you are in the market to buy a house (congratulations!). That is a big decision and I encourage you to think about where you want to be in 10 + years. You can also call the program and see what they recommend.
I commute from Long Beach, and it was rough in the beginning, but now I do not mind it. There are people that come from further away. You can PM me if you have more questions.
