There are pluses and minuses to living further away from school. I live about a 15-45 min. (depending on traffic) drive away from school, and I'm one of the furthest out. One guy in my class lives about an hour away, and he's repeating first year; so, do with that what you will. People who live further out fall into one of two categories; they either stay at school nearly all day long studying since they don't really have the option of driving back if they go home, or they rush to get home immediately after classes and labs finish (which kills people in anatomy).
One thing to consider is whether you want to be social with your classmates. Most of my classmates live one of three neighborhoods close to the school, and I feel like I miss out on a good deal of socializing. However, if you're the type who is adamant about not letting medical school consume your life and want mostly non-med student friends, people who live further out say they love being able to get completely away from school at the end of the day.
You might be able to pull it off for the first two years, but third year will kill you. I never see my third year roommate because she leaves around 6 AM and gets home anywhere from 6 PM-11 PM depending on her rotation and usually heads straight to her room to study for shelves or go to bed.
