I owe about the same. ~98K (69K at 3.25%, 28K at 6.8%). My monthly payments on the higher rate loan is about $336, which comes out to little over 4K per year.
1. Better to keep hitting away at the 28K with 4K a year for the next few residency years? Or where can I invest it somewhere that earns at least the 6.8%?
2. If I start paying now, will I be eligible for forbearance when I reapply again in December? Does paying off huge sums make it harder to get it because then I would have to explain why I need forbearance if I can pay my loans somewhat? Or forbearance they don't care about?
