I have a student rental property that is 1 block away from official campus grounds. That allows them a 5-10 minute walk to pretty much anything of interest.
Whether or not a 10-15 minute drive is too far depends entirely on your market and whether your college is considered a "commuter's school." There is another community college nearby where everyone is expected to drive. It has huge parking lots. But the public school where I am investing near encourages public transportation, walking and biking. It's actually a huge pain to park your car anywhere nearby. If your school is more pedestrian oriented like my local public school is, a 10 minute drive is not something students would choose to do. Even a 5 minute drive really. If they can't walk/bike/public transport to class within 20 minutes or less, it's too far.
I was looking at multiple properties along one street recently and found that even on the same street, a house next to campus will go for about 10%-15% more than an equivalent house just a few blocks down the street. There is a sharp drop-off of the type of renter the farther you go from campus.
@Matt George is right that rent for student housing next to campus is ridiculously high. But that doesn't necessarily mean better performing properties, because increased rent means higher property taxes (higher assessed value) and also dramatically increased insurance rates. Students also cause more damage so you have to factor in more maintenance.
