Refinancing your student loans can lead to better rates and terms on your education debt. But if you don’t have good credit, it’s tough to qualify for a lender’s best rates. That’s where a cosigner comes in.  By applying with a creditworthy cosigner, you can boost your chances of qualifying for the lowest rates. Adding a cosigner can also help you get approved if you can’t meet a lender’s criteria on your own. However, there are both pros and cons to refinancing student loans with a cosigner, which are worth reviewing before you sign on to share debt. Let’s take a closer look at refinancing student debt with a cosigner, including both the advantages and potential disadvantages. Recommended: Average Student Loan Debt 2023-2024

Can You Refinance Your Student Loan With a Cosigner?

Many lenders give you the option of student loan refinancing with a cosigner. When you apply with a cosigner, you’ll both provide your personal and financial information on the refinancing application. If your cosigner has a good credit score and positive credit history, they could help your chances of qualifying or even get you better rates. Some refinancing lenders that let you apply with a cosigner include SoFi, Laurel Road, and Citizens Bank. Not all refinancing lenders permit this option, however. Earnest, for instance, does not allow cosigners on student loan refinancing applications at this time. Some lenders also offer the option of releasing your cosigner after a certain period of on-time payments, typically a year or more. Cosigner release can remove your cosigner from the loan, but it’s not automatic. You’ll need to apply and be approved. 

Pros of Refinancing Student Loans With a Cosigner

Adding a cosigner to your student loan refinancing application can be beneficial if you can’t meet a lender’s underwriting requirements on your own. Most lenders require good credit and a stable source of income to refinance student loans. Basically, they look at your financial situation to make sure you’re likely to pay back your loan in full and on time. If you don’t have good credit — or don’t have much of a credit history — it could be hard to qualify for student loan refinancing. Or even if you do qualify, you might only be offered high rates that won’t save you much money in the long run. Adding a creditworthy cosigner could unlock the door to student loan refinancing. A lender will be reassured by the addition of a creditworthy cosigner and make you a better offer as a result. 

Cons of Refinancing Student Loans With a Cosigner

First of all, refinancing a federal student loan with a private lender means you will lose eligibility for income-driven repayment programs and forbearance programs on that amount.There are both pros and cons of refinancing with a cosigner. While adding a cosigner to your refinancing application could benefit you, it might not be so advantageous to your cosigner. For one thing, your cosigner becomes just as responsible for the debt as you are. If you miss payments, a debt collector could call your cosigner and demand that they pay. Plus, their credit will get damaged if you miss payments or your loan goes into default. Cosigning on debt will also increase their debt-to-income ratio. A high DTI ratio could make it harder for your cosigner to take out additional loans, whether they want to borrow a mortgage, business loan, or student loan for your sibling. If your cosigner has no plans to open a loan or new credit card in the future, this may not be an issue. And if you make consistent, on-time payments on your refinanced student loan, this could actually help your and your cosigner’s credit.  But it’s important to keep in mind that missing payments on your student loans will hurt the both of you. Before asking someone to cosign, make sure you’re both on the same page about what cosigning means and who’s responsible for paying off the student loan. By clarifying expectations upfront, you can avoid hurting your cosigner’s finances or straining the relationship.

Do You Have to Have a Cosigner to Refinance Student Loans?

You’re not required to have a cosigner to refinance your federal student loans. If you can meet a lender’s criteria for credit and income on your own, you can refinance the student loans in your own name. In fact, you might decide it’s not worth refinancing your student loans with a cosigner and would instead prefer to refinance solo so you can assume full responsibility for your debt. Some students refinance parent loans in their own name, for instance, to take the burden off their parents. What’s more, some refinancing lenders don’t allow you to apply with a cosigner. They require that you qualify on your own merits, or you can’t refinance at all. 

How to Find a Cosigner

Say you know you want to do a student loan refinance with a cosigner. Who should it be?A cosigner should be a trusted adult with decent credit and a source of income, but they don’t necessarily have to be related to you. Your cosigner could be a parent or guardian, but they could also be a trusted friend or a spouse. That said, your cosigner will need to meet other lender requirements, such as being the age of majority in their state (typically 18) and holding a valid Social Security number or tax identification number. The exact requirements will vary by lender, but they will apply both to you as the primary borrower and any cosigner you add to your application. Recommended: Guarantor vs Cosigner: What's the Difference?

The Takeaway

Applying to refinance student loans with a cosigner could unlock the door to more agreeable rates and terms. Adding a cosigner can also help you qualify in the first place if your credit isn’t up to scratch.However, asking someone to cosign on debt is a big ask. Not only will the loan show up on their credit history, but your cosigner will be considered equally responsible for paying back the debt. If your loans fall into default, a collections agency could pursue payments from your cosigner. Before you go all in with a cosigner, therefore, it’s a good idea to have a clear conversation about all the pros and cons. Plus, make sure you’re both on the same page about who’s responsible for paying back the loan and how they will afford payments.  Once you’re ready to move forward, take some time to shop around with multiple refinancing lenders to find your best rates.
