If you are a homeowner who was lucky enough to buy when mortgage rates were low, you may have no interest in refinancing your present loan. But perhaps you bought your home when rates were higher. Or perhaps you have an adjustable-rate loan and would like to obtain different terms.

Should you refinance? This brochure will answer some questions that may help you decide. If you do refinance, the process will remind you of what you went through in obtaining the original mortgage. That's because, in reality, refinancing a mortgage is simply taking out a new mortgage. You will encounter many of the same procedures-and the same types of costs-the second time around.

Refinancing can be worthwhile, but it does not make good financial sense for everyone. A general role of thumb is that refinancing becomes worth your while if the current interest rate on your mortgage is at least 2 percentage points higher than the prevailing market rate. This figure is generally accepted as the safe margin when balancing the costs of refinancing a mortgage against the savings.

There are other considerations, too, such as how long you plan to stay in the house. Most sources say that it takes at least three years to realize fully the savings from a lower interest rate, given the costs of the refinancing. (Depending on your loan amount and the particular circumstances, however, you might choose to refinance a loan that is only 1.5 percentage points higher than the current rate. You may even find you could recoup the refinancing costs in a shorter time.)
