Adjustable Rate Mortgage

An Adjustable rate mortgage consists of an index and margin combined to determine your rate. The adjustable home loan rate is when the index either increases or decreases based on interest rate changes. Your frequency of a rate adjustment is dependent on the adjustable home loan rate program and adjustment periods you choose. Adjustable Rate Mortgages (ARMs) offer a lower interest rate to start, so your monthly payments are generally lower. But, the interest rate is adjusted at times, based on an "index". Some of the more popular indices include Treasury Bills (MTA), London Interbank Offered Rate (LIBOR) and the California's 11th District Cost of Funds.

All lenders then add a margin to the index to give you their final adjustable home loan rate. It’s best to use an adjustable rate mortgage calculator when shopping rates to give you an exact payment. Adjustable home loan rate mortgages could go up or down depending on the interest rates at that time. The safest bet is to find an adjustable rate mortgage with a CAP so that you have a limit on how high the interest rate can adjust for any given period.

All adjustable rate mortgages have an index and are directly or indirectly tied to interest rates. Your best choice for an adjustable home loan rate is to find the one that has the least volatile indexes. The longer the term of the adjustment period the more the borrower is protected from short-term interest rate fluctuations. For example, an ARM with a six month adjustment would be more volatile than a one year adjustment period; an ARM with a COFI index will be far more stable than a treasury index or Libor index.
