Mortgage Interest Rates Today are flexible due to their nature as a revolving line of credit. While making regular interest-only payments, the homeowner still retains the option to make lump-sum payments to pay down the mortgage principal. This way, monthly payments will be as small as possible, and when money is available the owner can make headway in paying off their mortgage.
