on another note if youre gonna consolidate for a long period of time i would try to get a fixed rate. A lot can happen with the interest rate between now and then and adjustable rate is risky.
Don’t consolidate your private loans with your federal (Stafford) loans. It will only drive up the interest rate on your federal loans. The only option you would have with a private loan is to refinance at a lower rate if you have better credit than you did when you took it out, or if rates have gone down. Neither seems likely in your case.
