Worrying about what kind of mortgage you want to take is hard enough, without also deciding on which interest rate index is going to be the deciding factor on what your interest rates on your Adjustable Rate mortgage will be!

The index is the underlying instrument that is utilized as a basis for the adjustment of the mortgage rate. Today, banks use various indices, such as the rate on government bonds, or the Fed Fund rate or the London Interbank Offer Rate(LIBOR).

The rate on an ARM is adjusted periodically upwards, or downwards, based upon the movement in the general interest rate market, but tied to a specific instrument. For example, if you pick the CD rate as your index, when CD rates go up, your mortgage rate will increase. ARMs have rate adjustment caps, so that the rate on your mortgage will only go up at certain intervals (every three or six months, for example), so that if the CD rate goes up, you may not have an increased rate for a few months, if your rate just adjusted recently. But be aw are, however, that if you just readjusted at a higher rate, and your index rate goes down, you are stuck with the increased rate until the next adjustment period.

Your ARM may be linked with the Treasury Bill rate, which is the rate the US Government pays on its 90 day investments. The Fed Fund rate is the rate banks pay to the Federal Reserve Bank to borrow money. Many of the international banks will employ the LIBOR as the index rate for loans.

How you decide upon the right index is dependent upon your particular circumstances and how you believe interest rates will change. If you have an ARM that uses CDs as its base, you can expect it to be very responsive to market moves. On the other hand, if your ARM is based on T Bills, it will move more slowly. Fastest of all in reaction time is the LIBOR, so if you feel that rates are falling and want to take advantage of each downward move, this is the one for you.

But in addition to these standards, new products are always been introduced on the mortgage market; an example would be the option ARM, that will let a homeowner decide how much mortgage he is going to pay each month! Of course, there is a minimum, usually the amount of interest, so the lender can guarantee its return, and then the balance goes toward the loan. People using this option should be careful about negative amortization, since they may never repay any of the principal if they always choose the lowest amount.

With this dizzying choice in interest rate scenarios for your mortgage, the best idea is to meet with a mortgage consultant who can explain all of them to you and advise you best on your needs.
