What is an adjustable-rate mortgage (ARM)?
An ARM loan is a home loan with an interest rate that adjusts throughout the life of the loan. The initial fixed-rate period is typically five, seven or 10 years. After the introductory rate term expires, the rate becomes variable for the remaining life of the loan based on an index and margin.
During the adjustable-rate period, the estimated payment and rate may change. An increase or decrease depends on the market. Market conditions at the time of conversion to the variable rate and during the adjustment period thereafter dictate your rate. A jumbo ARM loan can exceed the conforming loan limit of $832,750 and up to $1,249,125 in high-cost areas like Alaska and Hawaii.
5-year ARM loans
5-year ARMs generally provide the lowest interest rates and monthly payments during the initial rate period. These loans are ideal for borrowers who plan to move or refinance within the five-year period.
7-year ARM loans
7-year ARMs provide seven years of predictable monthly principal and interest payments at a low interest rate before any adjustments are made. If you expect to move or refinance within the seven-year period, this may be a good option.
10-year ARM loans
10-year ARMs are increasingly popular as they combine significant savings for the initial rate period with longer protection from market-based interest rate fluctuations.
