If your credit score or financial standing is less than perfect, you're not alone - Experian reports that 35% of consumers have a credit score less than 670, which in most cases, isn't high enough to qualify for a student loan refinance.

That's where bringing on a cosigner can make a difference. Adding a cosigner to your refinance loan can increase your likelihood of approval and may save you money by qualifying for a lower interest rate. Here's what you need to know.

Good to know:

Most refinance lenders require a score in the high 600s or above to qualify. If you don’t have this score, your cosigner will likely need it. Typically, borrowers with higher scores can access lower interest rates.

1. Compare lenders who allow cosigners

Many lenders offer student loan refinancing with the ability to add a cosigner. Before settling on a refinance lender, compare these factors to determine the right fit:

  • Cosigner release: If you fail to make your student loan payments, your cosigner becomes responsible for the loan, which could damage their credit. Given the added risk, a cosigner might feel better if cosigner release is an option. Cosigner release allows you to remove your cosigner from the loan if you meet certain eligibility requirements, such as making a certain amount of consecutive monthly payments.
  • Repayment terms: The length of time you have to repay your refinancing loan affects your monthly payments. A longer repayment term usually translates to lower monthly payments, but more interest costs over time. Review repayment terms from each lender so you can choose one that will fit with your budget. 
  • Interest rates: Many refinancing lenders offer both variable and fixed interest rates. Compare these rates and how each will impact repayment. Fixed rates lead to predictable payments and unchanging rates, while variable rates fluctuate, which means your monthly payments can change too.
  • Hardship options: Research potential deferment or forbearance options that would allow you to pause payments temporarily in case of financial hardship.
  • Unique benefits: Review any unique benefits from the lender that may improve your experience. For example, some refinance lenders offer an interest rate reduction for borrowers who set up automatic payments.

2. Find a cosigner with strong credit

To refinance student loans with a cosigner, you need to find someone eligible and willing to help you out. Stakes are high for cosigners. It's not just about using their positive credit history to get approved for a loan. Cosigners take on a major responsibility and legally must repay the loan if you fail to meet your payment obligations.

Typically, cosigners are family members, like a parent or sibling. Additionally, you need to ensure that your potential cosigner meets the criteria for a "good cosigner." Generally, that means a FICO credit score of 670 or above, and income and employment that can support the loan.

Tip:

Have a candid discussion with your cosigner about their responsibilities and expectations. If cosigner release is an option with your lender, discuss what that process looks like.

3. Complete an online application

Once you've chosen a refinancing lender and have an eligible cosigner, complete an online application. Fill it out completely and provide documentation for you and your cosigner, if requested. This can include:

  • Social Security number or a government-issued ID
  • Pay stubs and employer information
  • Tax returns, if self-employed
  • Billing statements for the loans you want to refinance
  • Account information for your student loans

If you submit an incomplete application, it may delay your approval or lead to a rejection. Double-check that you've filled everything out and provided the necessary documents for you and your cosigner. After you review your application, press submit, and wait for the lender's response.

Should you refinance student loans with a cosigner?

There are two scenarios where refinancing student debt with a cosigner could make sense:

  1. You can't qualify for a refinance loan on your own: If you have a FICO score that's less than 670 or your credit history has negative marks, you probably won't qualify for a student loan refinance on your own. Applying with a cosigner who has good credit could help you access these loans.
  2. You want to access lower interest rates: Various factors influence your interest rate, including your credit. You may qualify for a refinancing loan on your own, but if your cosigner has better credit, you could secure a lower interest rate - this can lower costs, making your loan more affordable.

FAQ

Can I refinance student loans with a cosigner?

Many private lenders allow you to refinance student loans with a cosigner. Applying with a cosigner can increase your chances of loan approval and could have a beneficial impact on your interest rate. While this can help you as a borrower, it's important to understand that a cosigner is responsible for the loan if it's in default.

What are the benefits of adding a cosigner to my loan?

Getting approval for a loan is difficult if you have limited credit history or a poor credit score. When you add a cosigner with excellent credit and a stable income, your chances of approval increase because the cosigner agrees to repay the loan if the primary borrower stops making payments. Cosigners can help with approval, and as an added benefit, they can also help lower your interest rate.

What makes a good cosigner?

A good cosigner is someone with a good credit profile that's free of negative marks, and with a FICO score of 670 or above. Additionally, a good cosigner has a stable income and assets to fall back on if the loan ends up in default.
