Adjustable-rate Mortgage Information
An adjustable-rate mortgage (ARM) means that the interest rate changes over the life of the loan — according to the terms specified in advance. With ARMs:
Advantages: ARMs are usually priced lower than fixed-rate mortgages so you can increase your buying power and lower your initial monthly payments. If interest rates go down, you’ll enjoy lower payments. Usually an ARM is the best choice for homeowners who plan to relocate (for example, with their company or the military), or for those who are purchasing their first home and plan to be in the property only for three to five years. Remember that, on average, most people move or refinance within seven years.
Disadvantages: Your monthly payments can increase if interest rates go up. Keep in mind that ARMs are best for homeowners who aren't planning on staying with a property for a long period. If you’re on a fixed income, an ARM (especially a short-term ARM) may not be your best choice.
