ARM or the Adjustable Rate Mortgage
The Adjustable Rate Mortgage or the ARM is chosen by almost one third of mortgage applicants today. But most of the people who select the same do not understand how the ARM is calculated and how they can get benefits from selecting the same. Usually the ARM begins with a low introductory rate offer.
This rate then starts to fluctuate up and down during the tenure of the loan. There are a number of factors which determine the same and they are mentioned in the contract provided by the lenders. There are four main divisions of the ARM. These are the margin, index, adjustment period and the rate caps.
ARM and the index
Each ARM has a certain index to which it is tied. This index is usually the movement of a particular economic indicator. It can be anything which the lender wants so that your rate is tied to the same. These can be the one year Treasury note or prime rate index, cost of funds index or the COFI or any other related factor. These indexes can go up and down slowly or they can also be rapidly changing. It is best to choose an index which will be slow moving to avoid your finances from going on a roller coaster ride.
ARM and the margin
The margin is a vital part of the ARM. The total interest rate paid by the debtor is equal to the index rate plus the margin rate. The lender gives a number called the margin which will be added to the index. The margin can be 2.25% if the index is at 4%. This way the mortgage rate will be 6.25% which is derived by adding the margin and the index. It is the cost at which the lender does business and equates the necessary amount required to cover all expenses, profits and foreclosures.
The adjustment period and the rate caps
The adjustment period is determined by how frequently the lenders change the mortgage rate. This can be based on monthly, annual, six months, quarterly or any other related period. Usually the adjustment periods are 6 months and lenders check the index at the end of the period. The rate cap is the most crucial stability factor in mortgages. It shows the change of interest rates over the adjustment period. It helps the debtors from being affected by the rapid increases and decreases of rates. For example, if the debtor has a rate cap of 3% then the increased rate cannot be more than 3%. It is a tool that limits the lender from raising rates.
