I got a degree in accounting in a cheaper city, and moved to Boston after. It was the right move.

Dayton is... fine, but have you also considered something like.... UMass Amherst? It's under 2 hours drive/bus from Boston and the area is comparatively very affordable. Huge student population, many of whom have ties to Boston, so networking would be easier. As well, it wouldn't be unreasonable to take day-trips to Boston for job fairs, conferences... as well as fun & games.
