My son has a big loan to pay off, and while there were periods of low or no income he always communicated with the lender and always set up a payment plan within his budget when he got employment.
A way to put it in perspective — how much is a typical home mortgage ~ $300K. Tuition/Room and Board can be this high for a private school. Less if you shop around and even less if you go to a community college. Still, it can be close to $100K for a typical college.
Anyway, a #300K home mortgage usually takes 30 years to pay off!
Thirty years!!
That means that your typical student will still be paying the loan when they are in their 50s. And forget about getting a home loan with this kind of debt.
