Home buyers will find it easier to qualify for an adjustable rate mortgage than a fixed rate mortgage. Adjustable rate mortgages (ARMs), also known as floating-rate mortgages or variable rate mortgages, are attractive to many home buyers because of their low introductory interest rates. Know that these interest rates are tied to a fund index, which means your monthly payments will inevitably go up. It is essential to know which specific index a loan is tied to in order to properly evaluate it. Home buyers need to factor in higher payments after the initial term when determining the price range they can afford. Future payments could become so high that foreclosure may loom.

Beware of Teaser Rates

Adjustable rate mortgages often have teaser rates that lure in unwary home buyers. These unbelievably low interest rates inevitably climb. This low rate usually ends after six months or one year, and then the rate adjusts according to the mortgage's index. Generally, ARMs have monthly, yearly or lifetime caps that limit the allowable increases. Don't even consider a mortgage that does not have a cap. Caps preserve homeowners from extreme increases in monthly payments; however negative amortization can occur due to not significantly reducing the amount of principal owed.

Research a Potential Loan's Adjustment Period, Index and Margin

There are three additional items to look at with an ARM, the loan's adjustment period, index and margin. The adjustment periods of an ARM ranges from monthly adjustments to yearly adjustments and various other increments. ARMs with yearly adjustments offer more security, making certain of fixed amounts for at least a year's time, while ARMs that adjust monthly can be nerve-wracking.

The index of your floating rate mortgage determines the variance of the interest rate. Among these indexes are Certificates of Deposit, Treasury Bills and the London Interbank Offered Rate Index or even the banks' own index. Learn the index your loan is tied to and its performance as you decide whether to go with ARM or not. The margin is the amount your lender will receive as profit from your loan.

ARMs Attract Short-term Home Buyers

There are financial benefits to get this type of loan for some people. If you know that you will be receiving a promotion in the next year or so, you know you'll be able to handle the higher rates. If you'll only live there a short time, is another good reason to go with a lower ARM interest rate. If you plan to keep the property more than 5 years another type of loan would be more suitable. Possibly, a convertible or hybrid loan which begins as an ARM and changes to an Fixed Rate Mortgage or begins as an FRM and changes to an Adjustable Rate Mortgage may be the best choice.
