What exactly are you asking? Are you asking what to do simply from an "improve your credit" standpoint?
Regardless, if it's a Federal loan, be aware that just because the original entry might fall off your reports, the DoE can claim them ... that will put the loans right back on your reports. They can, IIRC, do this endlessly. So every time one set of loans falls off, another set replaces them ... but with higher balances since more than likely, you'll have an extra 20-30% in collection fees PLUS interest.
If I were you, I'd start rehabbing now. Even though you can, AFAIK, ALWAYS rehab, to do so now will be oodles cheaper -- and better for your credit!!!
Best of luck!!!
