Oh, not to mention the fact that this will be around 8K a year rather than 50-60k plus living expenses.

Seriously, though, the reason that I mention that is that DD isn't 100% settled on what she wants. Could be math, biophysics, statistics, neuroscience, toxicology, or something else entirely... and at a 60K a year school, she is going to be PAINFULLY conscientious about a desire to push through and graduate in four years. We'd rather that she took five if that's what she needs in order to choose well (if not "rapidly").
Polymath/multipotentiality problem, that. So we were trying to avoid the pressure of a cross-country move and high price-tag "for her" given her innate nature-- that's too much pressure for a 15yo with some socially-prescribed perfectionism, quite frankly.
