Co-Signer vs. Co-Borrower: What’s the Difference?

If you’re applying for a loan but struggling to qualify, you might benefit from a co-signer or co-borrower.

When you add a co-borrower or co-signer to a loan application, you’re giving a lender someone who can share the financial responsibility for repayment. Their creditworthiness may also help you land a lower interest rate than you would if applying on your own. Knowing the financial responsibilities of both roles can help you decide whether a co-borrower or co-signer is a better fit.

A co-signer is someone who is legally responsible for repaying your loan if you do not. Despite this obligation, the co-signer has no rights to the loan funds or ownership stake in the property.

The co-signer’s credit may help you qualify for a loan when your credit alone isn’t enough. When you have a co-signer, the loan can appear on your and your co-signer’s credit reports, which means missed payments can impact you both. Should the loan go to collections, the lender can seek repayment from you even before trying to collect from the borrower.

Oftentimes, a co-signer is someone close to you, like a family member or other loved one who may want to help support your financial goals. For instance, a child might have a parent with stronger credit co-sign a student loan or mortgage.

While adding a co-signer could boost an applicant’s approval odds, there are pros and cons for potential co-signers to consider. They include:

When you apply for a loan with a co-borrower, the lender considers information from you both. Then, when your loan is approved, you and your co-borrower share legal responsibility for the debt and, typically, rights to the loan proceeds or asset. For example, if two people are co-borrowers on a mortgage, both would have their names on the title to the house.

Co-borrowing situations could include a couple taking out a mortgage or a parent and child taking out a car loan together.

Becoming co-borrowers can make sense if you share a financial goal with someone. This arrangement can have drawbacks, however, if you don’t plan ahead. Pros and cons include:

Both co-borrowing and co-signing can make qualifying for a loan at the best rates easier. But co-borrowing takes the commitment one step further and can offer more assurance to a lender and co-borrower.

“With a co-borrower, the lender feels like it’s less risky to have two co-borrowing instead of one (borrower), especially when it’s a large item like a mortgage,” says certified financial planner Rianka R. Dorsainvil, co-founder and co-CEO of 2050 Wealth Partners, a virtual financial planning and wealth management firm.

Co-borrowing makes sense when you have a common goal and shared ownership of the asset. “You typically don’t benefit from the asset being a co-signer,” Dorsainvil says. “It’s more to help someone out – such as a family member or friend.”

If a friend or loved one asks you to co-sign a secured loan, you might want to insist on being a co-borrower in case the primary borrower skips payments and becomes hard to reach.

One scenario that could come back to haunt a mortgage co-signer is if the primary borrower dies and the co-signer inherits the payments but not the property.

“In this situation, the co-signer won’t have ownership, so they have no stake in the equity position,” says Brian Snerson, a retirement income certified professional and managing director at Essex Wealth Management. “The property would go to the surviving spouse or the estate. The co-signer would still be responsible for the debt. As a co-borrower, you maintain control of the asset in event of untimely circumstances.”

Co-signing and co-borrowing place heavy responsibilities on all involved. Putting a few guardrails in place can help set you up for borrowing success.

No one wants to plan for a breakup. However, if your relationship with the borrower or your co-borrower ends, one person might neglect the payment and not care how it affects the other’s credit score, Dorsainvil says.

To remove a co-borrower’s name from a loan, you would need to refinance. Yet in some cases, that might cause other challenges. “You may be stuck with a bigger payment that you cannot afford on your own,” Dorsainvil says.

When you agree to co-sign or co-borrow, you might forget about it until it comes up during a different loan application process.

Dorsainvil says one of her clients co-signed a car loan for a sister, who said she would pay it off quickly. But years later, it still appeared on the client’s credit record and prevented him from getting a mortgage until she refinanced the loan and removed his name.

“You need to understand the goals you have for yourself financially,” Dorsainvil says. “How does being a co-borrower or co-signer affect your personal financial goals?”

If you decide to become a co-signer or co-borrower, you’ll need a strategy to communicate – during the best and worst of times.

“Most often, you become a co-borrower or co-signer to help a family (member) or friend and assume everything will go smoothly, but it is important to have a plan for the problems that might arise and an agreed process for discussing those issues,” says Gary Cloudman, head of fiduciary services at Angeles Wealth Management.

If you opt to co-sign a loan, you and the borrower could agree to regular loan updates to make sure everything stays on track. You may also want to discuss how the borrower will let you know about any struggles they may face making payments on time.

Co-borrowers can also benefit from scheduled conversations. Since financial topics can be difficult to broach – even with those you love – a regular month-end or quarterly review of your finances could give you a way to talk about the loan and cash flow in a nonconfrontational way. From there, you can make decisions together that keep payments on track and protect your shared interests.
