Don't rely on published rates. "No one's going to advertise their worst product," says Keith T. Gumbinger of HSH Associates, a Butler, NJ, firm that tracks mortgage rates. "They advertise the best possible rate, which probably gets offered to only the top 10 percent of applicants."
If you are paying private insurance on your current mortgage, refinancing may allow you to do away with this unnecessary expense.
It's better to follow the 2% Rule which suggests that you can enjoy the benefits of a home refinance if your mortgage refinance rate is 2% lower than that on your current loan. The interest savings will help you recoup the costs you've paid for the new loan provided you stay in the property for a certain period of time (break-even period). However, there are no-cost as well as low-cost refinance loans wherein the costs are included into the loan. But you can expect comparatively higher rates on such loans. Moreover, these loans are limited when the market is in a credit crunch.
Ask the lender or broker for a comparison of the up-front costs, principal, rate, and payments with and without this rate trade-off.
Don't fall for the 0% apr unless it fits in with your master plan. A lot of brokers will try to get you locked into a low interest rate that will balloon on you in a couple of years and leave you out on the street.
