Q&A: Why co-signing a loan, especially a student loan, can be a costly move

Dear Liz: I co-signed a student loan to help a 31-year-old woman complete her schooling to become a nurse. I know this was something I should not have done, but I just could not refuse her. I did not realize that because no payments had to be made until after the student’s graduation, the loan amount would double. I am looking into a life insurance policy on the student to protect my interest.

Is there any advice you can provide me other than paying off the loan? I know the student can complete a form to take me off this loan, but she will not qualify on her own.

Answer: She may not be able to take you off the loan now, but hopefully she can within a few years of graduation. Most private lenders will allow a co-signer to be removed from a student loan after a certain number of on-time monthly payments, typically 12 to 48. If she has good credit and a decent income, she also may be able to refinance this loan with another lender to get you off the note.

In the meantime, you’ll want to protect your credit, because a single missed payment can damage your credit scores. Contact the lender to find out what notice, if any, you’ll get if she falls behind on payments. Discuss with her the importance of making payments on time, every time, and ask her to contact you immediately if there’s any chance that won’t happen.

Just as many people don’t realize that they’re putting their good credit in the other person’s hands when they co-sign a loan, many also don’t realize what can happen if they take a lender up on its offer to defer payments until graduation.

The loan amount swelled because of something known as capitalization. Because payments aren’t being made, the unpaid interest is being added to the loan amount and dramatically increasing what the two of you owe.

If the loan were a subsidized federal loan, the government would pay the interest while the student was in school. With unsubsidized federal loans and private student loans like the one you signed, it’s smart to start making payments immediately to avoid capitalization and having to pay interest on interest.
