Cost of Loyola

My parents have agreed to pay for half of my college education. Rather than take out loans, they will pay the initial cost and have me pay them back with no interest as I move on after college. I come from a middle class family and have a sister in college now, so I didn't get a huge amount of aid, nor can we easily afford Loyola. I love everything about the school but the cost is ridiculous, averaging about $44,000. With my scholarship of $12,000, that makes it around $32,000 for this school. I have a job now, and hopefully will get one when at school. Will most people at Loyola graduate with a bunch of college debt? At the rate I am going, I will leave Loyola with around $70K in debt to repay to my parents. Is that reasonable?
