자주 묻는 질문

Does cosigning hurt your credit score?

Cosigning immediately impacts your credit through a hard inquiry (5 to 10 point drop) and increased total debt. If the primary borrower pays on time, it can actually help your score. If they miss payments, your credit takes the same damage as if you missed payments on your own account.

Can you remove yourself as a cosigner?

It's difficult. Some loans offer cosigner release after 12 to 24 months of on-time payments by the primary borrower. Otherwise, refinancing is usually the only option. You can't simply ask the lender to remove your name from an existing loan.

Does a cosigned loan show up on your credit report?

Yes. The full loan balance, payment history, and account status appear on your credit report as if it were your own debt. Lenders calculating your debt-to-income ratio will include the cosigned loan's monthly payment.
