Adjustable Rate Home Mortgage Loan (ARMs- Adjustable Rate Mortgages) is the type of Conventional Loan. The most important characteristic of ARMs is that its interest rate is linked to economic index. Payments are adjusted periodically as these indexes go up or down. An index is a guide used by lender to calculate the changes. Some commonly used indexes are-
* Constant Maturity Treasury (CMT)
* Treasury Bill (T-Bill)
* 12-Month Treasury Average (MTA or MAT)
* Certificate of Deposit Index (CODI)
* 11th District Cost of Funds Index (COFI)
* Cost of Savings Index (COSI)
* London Inter Bank Offering Rates (LIBOR)
* Certificates of Deposit (CD) Indexes
* Bank Prime Loan (Prime Rate)
* Fannie Mae's Required Net Yield (RNY)
* National Average Contract Mortgage Rate
A specific index is provided by different lenders. Not only this interest rate is paid by the borrower, a margin is also paid in addition to the interest according to economic index. Margin is the profit made by lender and it remains same throughout the life of the loan for Adjustable Rate Home Mortgage Loan. The result is then rounded to nearest one-eighth of the percent.
The index is 5.3% and the margin is 2.5%,
then the new interest rate = 5.3% + 2.5% = 7.8%.
The nearest to 0.8% is 0.75% = 6/8%.
The result will be 7.75%.
Now the question arises why a person should go for ARM? It can help people in many ways because the rate of interest remains same as it was on the day you signed the loan papers for Adjustment Period for some time. Adjustable Rate Home Mortgage Loan is described with figures like 1-1, 3-1, and 5-1. The first figure refers to the adjustment period and next refers how often the adjustments will be made.

Some sellers, especially new home builders pay buydown fee in order to attract buyers by making it easy for them to avail Adjustable Rate Home Mortgage Loan. Actually, by depositing buydown fee lenders decrease the initial interest rates than the sum of index and margin as well. But this rate expires and later borrower has to bear all the charges, moreover sometimes sellers increase the cost of their home to cover the amount of buydown fee.
Interest Rate Caps limit the amount you are charged, they are of two types- Periodic caps and Overall caps. Periodic caps limit the amount increased from one adjustment to another on the other hand Overall caps limit the amount increased over the life of the loan.
