The Secret to Understanding ARMs
by Camilla D. Patterson
As if there were not enough choices to make when you are purchasing a house and getting a mortgage, lenders now have such a wide rang of ARMs (adjustable rate mortgages) and the borrower even has to decide upon the index upon which the ARM will be based!
When we speak of the “index”, we are speaking of the base financial instrument that the changing rates will be based on. Today, banks use different indices, such as the rate on government debt, or the Fed Fund rate or the London Interbank Offer Rate(LIBOR).
The basic idea of an ARM is that the interest on the loan is adjusted up or down, periodically, based on a chosen underlying interest rate that is indicative of interest rates in general. For example, if you pick the CD rate as your index, when CD rates go up, your home loan rate will go up. ARMs have rate adjustment caps, so that the rate on your home loan will only go up at certain intervals (every three or six months, for example), so that when 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 tied to the Treasury Bill rate, which is the rate the US Government pays on its 90 day investments. The Fed Funds rate is another very popular basis for ARMs. Another popular index used by a lot of lenders is the LIBOR, or the London Interbank Offered Rate, which highly rated international companies pay to borrow.
Deciding upon which index is the one for you will depend on your own situation as well as your view of interest rate movements. Adjustable rate home loans that use CDs as the reference rate tend to change more quickly. Adjustable rate mortgages that use T Bills will change more slowly alberta mortgage. LIBOR is one of the quickest moving indices, so if you want to take advantage of quickly falling interest rates, this is the one to use.
An option ARM is one where the interest rate adjusts monthly and the payment adjusts every year, and the borrower is offered an “option” on how large a payment he wants to make. The options that are offered are interest-only payments, and a lowest possible payment that can’t be less than the interest-only payment alberta mortgage brokers. One of the big issues with an option mortgage is that you can end up with an increasing instead of decreasing mortgage; this is also known as negative amortization.
There are so many choices in the home loan market today that the new home buyer should not try to cover this field by himself but should instead call a certified mortgage expert.
