* Editor's Note: I love the premise of refinancing through these startups (full disclosure: my summer internship was at SoFi during business school), but for all these people who get on their soap box and talk about refinancing your loans as quickly as possible, I would say the following: these are awesome solutions if your loans are private, as they quickly will reduce your interest rate. Go for it! If your loans are federal, however, I would think hard about choosing to refinance with them, as you'll opt out of the ability to use one of several types of repayment plans that are solely based on your adjusted-gross income. Sure, your rate will be better, but your payments will be much higher. Understand your situation first.
