You may certainly refinance an existing OU Credit Union auto loan! Please know that if the interest rate on the loan is being lowered during the refinance, the vehicle must also have at least $1,000 in available equity at the time of the refinance. The equity is determined by an OU Credit Union Representative based on the NADA Clean Trade-In value. This amount will then be added to the balance of the loan with the lower rate and can be deposited into your account for you to use for any purpose. You can apply for an internal refinance over the phone at 248-364-4708, via Live Chat, or online by selecting "Apply for a Loan" when logged into your account via ComputerLine and selecting Apply for a Loan.
