ARM loans have caps on how much the interest rate can shift on the initial adjustement, how much the interest rate can shift on subsequent adjustments & how much rates can rise over the duration of the loan. For a 5/1 ARM the first 5 years would charge a set rate of interest & then after the 5 year introductory period is up the rate of interest resets annually based on the performance of a referenced index like COFI or LIBOR.

Most ARM loans are hybrid loans which have an introductory period that acts similarly to a FRM in the initial portion of the loan. Fixed vs ARMĪdjustable-rate mortgages (ARMs) get their name because the rate of interest is variable and can change as economic conditions change. If interest rates fall homeowners can refinance into a lower rate loan. If interest rates rise the home buyer is protected from spiking rates. Both the 10-year and 20-year combine to have under a 10% share of the market.įRMs are a one-way bet for consumers. The 15-year is the next most popular fixed-rate loan, with loans of other durations far less common.

The most popular FRM is the 30-year loan as it enables consumers to lock in a low rate of interest for an extended period of time & have low monthly payments. This means the rate of interest & monthly payment toward principal and interest will not change throughout the duration of the loan. Fixed-rate mortages (FRMs) get their name because the rate of interest charged throughout the duration of the loan is static or fixed.
