i'm planning on between 15 and 30 minutes each way, depending on traffic.
the way i see it, if i'm 30 minutes each way, I have an hour less to do constructive activities.
i'm married, so we like to look at it as an hour less time together. but it could just as easily be study time, or relaxation time.
of course, i would like to be closer to school. but some schools are in areas that make homebuying prohibitive. in chapel hill, where i will be attending school, home prices in the entire COUNTY average over 275,000.
um, i can't afford that.
15 extra commute minutes give me the opportunity to have a much better home. and the same thing often applies to rentals as well.
the two factors are time and your home/apartment. more time, less home. more home, less time. you have to find a balance.
