If you can no long afford to make the monthly payments on the mortgages the few options you have to look into would be a short sale, foreclosure, and bankruptcy.

With respect to your credit card debt you may want to look at the few different options consumers have. The first option is that you can try to consolidating the credit card debts with a personal loan from a bank. If you are unable to obtain a loan you may want to consider a consumer credit counseling or debt settlement program. In a credit counseling program the credit counseling will negotiate reductions in your interest rates with your creditors. You will still pay off the balance entirely with regular monthly payments. This typically will show up on your credit report as a third party assisting you with your unsecured debts. With a debt settlement program regular monthly payments are not disbursed to your credits. Your money is set aside and builds up to negotiate a reduction in the overall balance you owe to your creditors. Monthly payments are typically much less that what the creditors demand. This has a short term negative impact on your credit scores. If you would like to learn more about how debt relief works I recommend you read What Are My Debt Consolidation Options?.
