Keep or Surrender your Home
Keep your Home and keep paying for it or Surrender and be done with it. So your regular house payments continue if you are keeping your house. Iowa has an unlimited homestead exemption. If you plan to surrender you can probably stay in the home without making any mortgage payments for months if you want to save some money. If you are surrendering your home in Chapter 7 you will discharge all of the mortgage debt (first mortgage, second mortgage, home equity loans, lines of credit etc.) even if the home is later sold for less than what you owe.

Keep or Surrender your Car(s)
If you own your car(s) outright, you can keep up to the $7,000 exemption amount single or two if you are filing a joint bankruptcy and are each on at least one title. Cars with little value are often fine too. If you have loans you can keep the car(s) and keep making the payments of surrender them and discharge the debt.
