The requirements to qualify for refinancing can vary by lender. However, there are a few common eligibility criteria you’ll likely come across, including: Good credit: You’ll typically need good to excellent credit to qualify for refinancing — a good credit score is usually considered to be 700 or higher. While some lenders offer refinancing for bad credit, these loans generally come with higher interest rates compared to good credit loans. Verifiable income: Some lenders have a minimum required income while others don’t — but in either case, you’ll likely need to provide documentation showing proof of income. Low debt-to-income ratio: Your debt-to-income (DTI) ratio is the amount you owe in debt payments each month compared to your income. Lenders typically like to see a DTI ratio of 50% or below — though keep in mind that some lenders might require lower ratios than this. Loan information: The lender will need information regarding each of the student loans you want to refinance, such as loan balances, your current lenders, and what schools you attended. If you’re struggling to get approved for refinancing on your own, consider applying with a cosigner to improve your chances. A cosigner simply needs to be someone with good credit — such as a parent, other relative, or trusted friend — who’s willing to share responsibility for the loan. Even if you don’t need a cosigner to qualify, having one could get you a lower interest rate than you’d get on your own.
