Many students choose to live in an apartment complex or house not too far from campus so that they can still have a place to stay without losing the ASU experience. Off-campus housing is definitely worth it because it is much cheaper than living on campus, you have more room to breathe, you won't be getting your stuff mixed up with your roommate's as easily, four people don't have to share one bathroom, and most importantly, you have more space to invite people over and have a good time! Most prefer to live off-campus so that they have more freedom to do as they please and don't have to worry about a community assistant catching them with inappropriate substances.
There are apartments and student housing all around the Tempe area, so there is no need to be concerned about the availability of off-campus housing. Even if you are not interested in living within 10 minutes of campus, there is all sorts of housing across the Phoenix area that you could check out as well. While some places may look pretty ghetto and others exceptionally luxurious, you will be getting exactly what you pay for. For instance, places like The Vue, Vista del Sol, Block 1949, Grigio Metro, and glamorous student living will come with a high price, so be ready to throw down some cash. If you live with roommates, however, it will help cut costs. There are plenty of places around Tempe, so take a day to check it out. You will surely find one that fits your lifestyle and price range.
