If any. I know ballers here might think a $7-10K/year swing is nothing, and maybe it isn't in high finance. But kids can change their mind, maybe not get into finance, so that $30-40k could take longer to payoff. Could be adding years of interest if student ends up in law or grad school, Peace Corp, on and on, who the heck knows.
Anyways, how much better, if at all, are the three privates over a Ross BBA?
