Refinancing medical school student loan debt....

Now that my son is almost a PGY3 (time flies!), he’s wondering if he should refi his med school loans. He doesn’t have a crazy amount, but he’s not happy with the fed rate he does have.

Anyone do this? Pros? Cons? Which lenders are best at this? Who to avoid? Anything to look out for?

D and SIL are on IBR (income based repayment). I know there are multiple repayment options, that works the best for them

I know a couple of people who refinanced their med school loans with First Republic. These 2 people were very, very happy with the process and end result.
