I graduated from college 3 years ago and have a 20K student loan to pay off which is consolidated. Currently I'm paying 3.75% which I think is a little high. My lender is Chase. I'm not sure about how loans work, but is it possible to go through another lender that would give me a lower interest rate? Does it work like a "Refinance".....how does it work....would Chase transfer my loan to them and I start paying a lower interest while also paying my principle? thanks
