I agree with @TheBigChef.
For us, we did not think that full cost at BU was worth it when compared to a very good in-state public university (and we do not drive a BMW).
One daughter who attended a very good public university just got accepted to a very highly ranked graduate program which suggests that she did just fine with a degree from a public university. My wife and I also have experience at highly ranked graduate schools studying alongside a very large number of other graduate students who had graduated from a very wide range of universities, most of which were probably in-state public schools.
I went to undergrad across the river from BU, and did know a few Jewish students at BU. They seemed to have a large and active Jewish community and were fine with it. Some of them did date non-Jewish guys from other universities in the area.
I would save my money for undergrad. I am more willing to shell out the big $$$ for graduate school.
