Does anyone know the minimum balance you can have on your student loan accounts with Navient before they make you pay it in full? I know I read it somewhere, and naturally now I can't find it. I am thinking about doing a balance transfer (0% for 9 months) to tackle my mountain of student loan debt. Only planning on doing $600-$800 at a time and then putting my extra payments towards the CC instead of my student loans and saving a bit on iterest. My smallest loan is under $600 and I know I don't want to pay it off completely.
