In recent years, Americans seeking to take advantage of low interest rates have lined up to refinance their mortgages. In fact, refinancings hit an all-time high in 2003, and remained high in both 2004 and 2005, according to the Mortgage Bankers Association of America.

But while it's true that refinancing has the potential to help you reduce the costs associated with borrowing money to own a home, it is not necessarily a strategy that makes sense for every individual in every situation. So before you make a commitment to refinance your mortgage, its important to do your homework and determine whether such a move is the right one for you.

The old and arbitrary rule of thumb said that a refi only makes sense if you can lower your interest rate by at least two percentage points for example, from 9% to 7%. But what really matters is how long it will take you to break even and whether you plan to stay in your home that long. In other words, make sure you understand -- and are comfortable with -- the amount of time it will take for your overall savings to compensate for the cost of the refinancing.

Consider this: If you had a $200,000 30-year mortgage with an 8% interest rate, your monthly payment would be $1,468. If you refinanced at 6%, your new monthly payment would be $1,199, a savings of $269 per month. Assuming that your new closing costs amounted to $2,000, it would take eight months to break even. ($269 x 8 = $2,152). If you planned to stay in your home for at least eight more months, then a refi would be appropriate under these conditions. If you planned to sell the house before then, you might not want to bother refinancing. (See below for additional examples.)

Don't make the mistake of choosing a mortgage based only on its stated annual percentage rate (APR), because there are a variety of other important variables to consider, such as:

The term of the mortgage -- This describes the amount of time it will take you to pay off the loan's principal and interest. Although short-term mortgages typically offer lower interest rates than long-term mortgages, they usually involve higher monthly payments. On the other hand, they can result in significantly reduced interest costs over time.

The variability of the interest rate -- There are two basic types of mortgages: those with "fixed" (i.e., unchanging) interest rates and those with variable rates, which can change after a predetermined amount of time has passed, such as one year or five years. While an adjustable-rate mortgage (ARM) usually offers a lower introductory rate than a fixed-rate mortgage with a comparable term, the ARM's rate could jump in the future if interest rates rise. If you plan to stay in your home for a long time, it may make sense to opt for the predictability and security of a fixed rate, whereas an ARM might make sense if you plan to sell before its rate is allowed to go up. Also keep in mind that interest rates hovered near historical lows in recent years and are more likely to increase than decrease over time.

Points -- Points (also known as "origination fees" or "discount fees") are fees that you pay to a lender or broker when you close the deal. While a "no-cost" or "zero points" mortgage does not carry this up-front cost, it could prove to be more expensive if the lender charges a higher interest rate instead. So you'll need to determine whether the savings from a lower rate justify the added costs of paying points. (One point is equal to one percent of the loan's value.)

Finally, keep in mind that your current lender may make it easier and cheaper to refinance than another lender would. That's because your current lender is likely to have all of your important financial information on hand already, which reduces the time and resources necessary to process your application. But don't let that be your only consideration. To make a well-informed, confident decision you'll need to shop around, crunch the numbers, and ask plenty of questions.
