The choice between a fixed-rate mortgage (FRM) and an adjustable-rate mortgage (ARM) comes down to one question: how long do you plan to keep this loan?
After the fixed period, an ARM adjusts based on a market index.
Fixed-rate mortgages. Your rate, and your principal-and-interest payment, stays the same for the life of the loan. The upside is predictability. The downside is that you usually pay a slightly higher rate for that certainty.
Adjustable-rate mortgages. Typically offered as 5/1, 7/1 or 10/1 ARMs. The first number is how many years the rate is fixed. After that, it adjusts annually based on a market index. The initial rate is often lower than a comparable fixed rate.
Neither loan is inherently better. They solve different problems.
