SoFi is one of the more established student loan companies. They are known for having solid rates and great customer service. Generally, their rates are going to be 2.6%-7% with the lower rates for short term variable rate loans.
SoFi also allows medical residents to refinance. This is a great option even though the rates likely won’t be as good as they will be after residency. You would be smart to refinance now and then refinance again after finishing your training.
