Citizens Bank offers student loan refinancing for up to $750,000 if you have a professional degree, $500,000 if you have your graduate degree and $300,000 if you have your bachelor’s degree. That makes it a lot easier to consolidate your loans even if you’ve borrowed a large amount for your education. And while the upper ranges of Citizens’ student loan refinancing rates are higher than other lenders, a substantial 0.50% rate reduction is available if you’re already an account holder and sign up for autopay.
