I would recommend avoiding debt for a bachelor’s degree if you possibly can. It is not easy to make a living as a classical singer.
The good universities that I know for music are either public “state” universities in the US (U.Mass Amherst is good for music, but you are out of state), or expensive unless you can get aid (Julliard, New England Conservatory, Yale), or in Canada. There are quite a few very good music programs in Canada (big ones include McGill and Toronto, there are a few very good smaller less well known ones such as Acadia).
I do not know how good UNC is for music, nor specifically for voice.
