“In most states, a dealership has a 10-day period where they can cancel a purchase order. This cancellation can be for a variety of reasons, but most commonly, it’s because of the rejection of a financing application.
Since the lender denied your application and the dealer rescinded the purchase contract, you have to either bring the car back, collect your down payment (if any), and walk away, or you can try to find a different lender.
Keep in mind that if you got rejected on your first application, you’ll probably face a higher interest rate. But since you already sold the car you had, this still might be your best option.
If you find another lender, keep making payments on time. Then, refinance the vehicle when your credit score is higher.”
