The interest rate is one of the most important variables in your mortgage. Remember that buying a home requires a big investment on your part. Just the smallest change in the interest rate of your mortgage could mean huge savings for you.

If you refinance, you are simply replacing your original mortgage with a new one at better rates. You have to keep an eye on the fluctuations of mortgage interest rates. Remember that rates could decrease quite quickly. Even those who are not adept in banking and finance can easily follow the trends on mortgage interest rates. In case the rates are reduced to at least 0.5 percent, then you have to seriously consider refinancing your current mortgage.

Mortgage interest rates come in three common types. These are 30 years fixed rates, 15 years fixed rates, and 5/1 adjustable rates. There are still other types of rates. Fixed mortgage rates remain the same over the lifetime of your mortgage loan. On the other hand, adjustable rate mortgage means you have to pay a fixed rate for at least 5 years and then shift to an adjustable rate on the succeeding years.
