Each state offers some protection for your assets. To see your state list, google your state and bankruptcy exemptions will come up. If there is no equity
in the home, then you will be able to keep it by signing a document called a reaffirmation
agreement with both lenders.
For the cars, if they are older, they most likely won't be an issue, as the trustee
must get enough on a sale to make an equitable distribution to your creditors. Cars depreciate quickly, so unless they are new, they probably won't be an issue. Check the state exemptions though to be sure.
Bankruptcy can discharge all the consumer debt -medical, credit cards, loans etc. So it may be a good option. Some lenders will be willing to negotiate, but any discount they offer, may be taxable income to you, so be careful. There are debt consolidation companies out there, and many help, but you need to stay on top of it, and may need steady income to contribute to such plans, assuming all the creditors are willing to go this route. This hits your credit too, showing that you are paying them on a different schedule.
You should meet with a local bankruptcy attorney. They can help assure you that the assets will be protected, and help give you an idea if the bankruptcy would be your best option.
