You have a lot of choices to make in purchasing a house and deciding upon a home loan, and in today’s confusing mortgage world, you now also have to choose the index that you want for your Adjustable Rate Mortgage (ARM).

When we talk about the index for an ARM, we are talking about the standard that the adjustments to the mortgage rate will be tied to. Indices used include the CD rate, the Treasury Bill rate, the Fed Funds rate, the LIBOR rate and, the new kid on the block, the options ARM.

You must first understand that an ARM is a loan with an interest rate that moves up or down within a certain set period, and the movements are predicated upon the movements of the underlying index. If your index is CDs, and CDs go up, your mortgage rate goes up. ARMS also contain adjustment caps, so that you can limit the exposure as to how high your loan rate can go, even if your index rate continues to increase, which is good if you just had a change, and the rates go up again. Of course, the reverse can happen, and if your rate has just been readjusted at a high rate, and then the index moves down, you will not be able to take advantage of that until your next readjustment period.

The list of instruments that ARMs can be linked with reads like alphabet soup today, from CDs to LIBOR. Another index that is frequently used is the Federal Funds Rate. LIBOR is the London Interbank Offered rate, which is a rate that commercial borrowers pay each other to borrow money.

How you decide upon the right index is dependent upon your particular circumstances and how you believe interest rates will change. Adjustable rate mortgages that use CDs as the reference rate tend to adjust more quickly. ARMs that have the Tbill interest as the index do not move as often as the CD index. One of the fastest indices to move is the LIBOR, so if you want your interest rate to move frequently, because you think rates are falling, this is a good choice.

But in addition to these standards, new products are always been introduced on the market; an example would be the option ARM, that will let a borrower decide how much mortgage he is going to pay each month! The options that are offered represent interest-only payments, and a lowest possible payment that can’t be less than the interest-only payment. One of the big problems with an option mortgage is that you can end up with an increasing instead of decreasing mortgage; this is also called as negative amortization.

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