Who Should Choose a 7/1 ARM Mortgage?
Buyers who plan to move or refinance within 7 years, or those who want a longer fixed period than a 5/1 ARM.
ARM Rate Risk: After the initial 7-year fixed period, your rate adjusts annually based on market conditions. Rates could increase by up to 2% per year (typically capped at 5% above your initial rate). Budget for potential increases when planning.
