Another way to make a refinance work for you is to refinance for more than the balance remaining on your old mortgage -- in effect, tapping your home equity, or "cashing out," in mortgage speak. Thanks to favorable rates, you may be able to do so without boosting your monthly outlay. For example, at 6.5%, the payment on a $200,000, 30-year fixed rate mortgage is $1,264. But at 5.5%, that same payment lets you borrow nearly $20,000 more.
The best use for the extra cash is to pay off any higher rate loans you may have. Let's say that you are carrying a $15,000 car loan at 10% and making minimum payments on a $10,000 credit card balance at 17%. Your monthly payments on those debts would total $680. Then assume you refinanced your mortgage, taking out an additional $25,000 to pay off your car and credit card loans.
