Yes — if you refinance your student loans, you can choose whether you’d like to refinance some or all of your student loan debt. For example, if you have a mix of federal student loans and private student loans, you could refinance just the private student loans while leaving your federal student loans alone. This way, you could take advantage of refinancing for your private loans while maintaining the federal protections on your federal loans. Just keep in mind that once you’ve refinanced, it can’t be undone — you’ll have to decide beforehand how much of your student loan balance you want to refinance.
