I live about 35 miles from my uni, and had brief visits home once a term for medical appointments, and then for a couple of weeks at Christmas and Easter. I'm home all summer since my accommodation contract was only 40 weeks, but I'd probably stay at uni longer if I had a full year contract.
You might find some people go home more often if they get homesick or have extra commitments at home (e.g. I had a friend who went home every weekend for a job and medical care), but for the most part I've found term is too busy with work and socialising to be heading home much, no matter how close you live.
