I have to say that in my experience with interacting with the student body (2002-05) about 1/4 of the students I spoke with could not get into other choice schools and chose to go to UNT. 1/2 wanted a school that was close to home, and only a small portion of the remaining 1/4 chose to come to UNT for an academic program or something (the majority was because of how inexpensive it was).
Additionally, I would have to say that I believe the campus is quite run-down and in need of improvements (which they are attempting to make). When you walk or drive the campus there is no part that stands out as impressive...in fact, quite the contrary, see the tennis courts across from Fouts, or Fouts, or the broken parking lots all over campus, or the miss-matched buildings, or (prob the city's fault) the poor roads around campus. UNT may have strengths but their campus appearance isn't one of them....yet.
