Pretty open ended question since specialty salaries and malpractice vary so much, but I didn't want to post a poll and limit potential responses. The economics of borrowing a lot of money have to be considered and I am curious what others think is reasonable and unreasonable. So maybe put a specialty or expected salary with your idea of a "too much" cap on borrowing. Like $100,000 is the max for FP that is reasonable. Or maybe you think $250,000 is no problem for FP. With tuition and fees at some schools approaching $200,000 a total of $300,000+ is almost a necessity if there aren't other sources of income (parents, spouse) for living expenses. Is $300,000 a crazy number? $400,000? At some point a high paying specialty is required just to pay back loans in a reasonable or acceptable timeframe.
