When your property is repossessed interest stops so the total amount of your debt is fixed and wont doesn’t grow larger. You still need to pay it off or the leftover debt could be passed onto a debt collector. For example you might have $10,000 debt left on a car loan. If the repossessed car sells for $6,000, you still have to pay back $4000. The debt collector cannot add any fees or charges on the remaining debt.
