Adjustable-rate mortgages ARMs explained

A fixed-rate mortgage locks in your interest rate for the entire loan term, providing stability and predictable payments regardless of how high market rates rise. An adjustable-rate mortgage (ARM) typically starts with a lower fixed rate for an initial period (e.g., 5, 7, or 10 years), after which it adjusts periodically based on a market index. An ARM can be beneficial if you plan to sell or refinance before the adjustment period in a stable or falling rate environment, but it carries the risk of significantly higher payments if rates rise.

A fixed-rate mortgage provides predictable payments for the entire loan term, making long-term debt planning easier. An adjustable-rate mortgage (ARM) may start with lower payments, but if interest rates rise, your payments and total interest paid can increase significantly, potentially raising your overall debt load unexpectedly.

While both can have lower initial payments, they are structured differently. An ARM’s interest rate adjusts periodically after an initial fixed period, causing monthly payments to change. A balloon mortgage’s monthly payment is fixed, but the entire loan balance comes due at the end of the term, requiring a refinance or sale.

A fixed-rate mortgage has an interest rate that remains the same for the entire life of the loan, providing predictable monthly payments. An adjustable-rate mortgage (ARM) has an interest rate that can change periodically, usually after an initial fixed period, meaning your monthly payment can go up or down.
