For secured debts, the value of the underlying collateral must be paid to those lenders, which can also increase your overall debt burden under the plan. And because the debts take several years to be discharged, the debtor is expected to maintain payments during that time. If they cannot, then they may find their filing dismissed and collections and foreclosure procedures restarting.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
