Your living situation doesn't depend much on where you go-it depends on who's paying your rent... so I'll divvy up into three groups-
Group 1, Daddy's Little Doctorette: Lives alone in 3 bedroom condo with attached 2 car garage, as she cannot be expected to manuever her Lexus into a single parking space.
Group 2, Partnered and Loving It: Lives modestly in 1 or 2 bedroom apartment, with Sugar Daddy/Mommy who covers three-quarters of household expenses, allowing a better standard of living than Group 3. These ones tend to be dog owners and will socialize outside of the medical school.
Group 3: Poor Single Scum (about 90% of your classmates who came to med school straight out of undergrad) PSS has between one and nine roommates. Definitely shares a bathroom, possibly shares a bedroom. PSS attending school away from home tend to live with other med students (because your school will help you connect with others needing roommates).
