Undergraduates cannot take out more than about $7,500 in student loans each year. Anything over that would have to be a loan to your parents. How much debt do your parents want to take on, or can they take on? Even if money were not an issue, there is no way that Indiana is worth $67,000 more than Michigan State. It doesn’t sound like either of these universities will be affordable though.
The “best school you can go to” is not the one you can get admitted to – it’s the one that you and your family can afford. And if you think that someone can take on $115,000 in debt and “in the long run wouldn’t think twice about it” you are sorely mistaken. You think about it constantly if you cannot pay your bills or do the things you want to do because all your money is going toward paying off loans. Don’t do that to yourself or your parent(s). Stop looking at schools based on business school rankings primarily and look at them based on cost.
