Is MIT even an option?

Interesting…when I used the net price calculator for MIT, it only put our net price at $15,000/year which is actually doable. I see no reason not to let him at least apply (this was completely his idea). When/If we receive an acceptance for any of the colleges he applies to, will they give us an estimated net cost? Will we be able to compare financial aid packages, grants, scholarships, before we make a decision?
