Honestly not all colleges are the same. They are all different and have different costs. You could live in a traditional dorms or in suits. Also they have apartments style housing either furnished or unfurnished. Its all about what you can pay and what your comfortable with. The college that I go I pay $3500 a semester to stay in a nice traditional dorm, but you can get a little more than $1500 a semester in a traditional dorm. Ranges from $3500 for the nicest places to $1500 for shared traditional dorms. Remember it all depends. Hope this answered or at least helped answer your question! :)
On average, a college dorm costs $3,500 a year, or about $440 monthly, not including food. However, it values with every college. The most exspensive college dorm charges $15,460 room and board yearly (Eugene Lang College).
