The house and the car
Secured debt works differently.
A mortgage or a car loan is secured, meaning the lender holds a claim on the property itself. Chapter 7 can discharge your personal obligation to pay, but it does not erase that claim. In practice that means if you want to keep the collateral you generally need to be current and stay current, and there are separate mechanisms for reaffirming or redeeming.
If you are behind on a mortgage and want to keep the home, Chapter 7 is usually the wrong tool. Chapter 13 is the one built to cure arrears over time.
Tennessee also has its own set of exemptions covering a homestead interest, personal property, and tools of a trade. The amounts change, and how they apply depends on your household. Jonathan will walk through yours specifically rather than quoting you a number off a website.
