Many lenders are reluctant to work with people who want to take on debt immediately after Chapter 7. And since your score may have taken a severe hit, you’re looking at lenders that have sky-high interest rates.
For example, those who have a credit score below 600, which is common among those who have filed for bankruptcy, have an average car loan interest rate of 10.36% for new cars and 16.4% for used cars. That’s some pretty significant interest. Therefore, you should shop around as much as possible to see if you can find a decent rate.
Best of luck with everything!
