Hey,
Not sure if this helps but...they gave us an info sheet (don't have it in front of me b/c im at work) But it said something to the affect of most stay in NC to work....But a good # do not... they have employment recruiters from all over the country who want UNC students. Supposedly recruiters from cities such as Los Angeles, Wash DC, Tampa, New York etc.
I think that although many do stay in NC, it is still well recognized on the national level...
As for housing, our law school tour guide said most live near by on the free public transportation routes, or in nearby Carrboro neighborhood. She mentioned Meadowmont Apartments as a good place for law students (kinda expensive though)....
