Am I being realistic with any of these schools?

You might consider (use net price calculators):

Carnegie Mellon

University of Michigan (actually provides need based aid to some oos)

Case Western Reserve University

Usually student borrowing is limited to the federal loan $7500/yr (juniors/seniors) and whatever your parent is willing to borrow for you.
