Most of us have heard of ARM or, Adjustable Rate Mortgages, as well. They are generally called adjustable or variable loans. This type of mortgage and has received a bad reputation, because they are often not understood when they are purchased. If you are a "Rate Chaser" this may be a better option for you. You can save a little more money with this type of loan when compared to a fixed mortgage.
An adjustable rate mortgage is any mortgage that the rate changes at some point during the loan. These loans are also found in 15, 30 and sometimes 40 year loans. The majority of these loans have a fixed period during the loan; this usually ranges from the first 1 to 15 years. After this period they begin to "adjust" with the market. (The majority is 1, 5, 7, 10, and 15 years fixed but there are plenty of different types out there!!) The other portion of this mix is how often and to what index these loans follow. They can adjust every month, 6 months, or up to one year. Remember this is just a general description there are more types out there! The list of indexes these loans can follow is a long one.
