Hi Tom,
Completely avoid the apartments right in front of the school near Byrne...they are not very safe and I have heard some scary things that have happened there. The school is safe, but the apartments closest (ie. within walking distance) are not that great.
Have you considered rooming with another student? There are always signs posted at the school of med students, PT, public health, or grad students looking for roomates...you might look into that. The School of Medicine sends out a list of students looking for roomates in June when they're almost done with admissions. You could definitely find a much nicer place for that price or less if you had a roomate. Otherwise...my friend lives in BriarCliff Woods and pays 450/mnth...it's not the best place to live, but fairly safe.
