A bank makes a personal loan based on your credit and financial ability to repay the debt. Because you don't put up any collateral, such as a house or car, for a personal loan, it's considered an unsecured debt.ou must pay the bank principal and interest each month until you pay off the personal loan. Interest rates for personal loans are typically much higher than home loan rates, plus, the additional monthly payment reduces your mortgage borrowing power, increasing your debt-to-income ratio.
