Adjustable Rate Mortgages (ARMs) feature interest rates that adjust with time and may be lower initially than fixed-rate mortgages. You can choose an adjustment period of 3, 5 or 7 years.
Hybrid ARMs (3/1 ARM, 5/1 ARM, 7/1 ARM, 7/3 ARM): Get the best of both worlds, a period of stability before the loan adjustment period begins.
