How does an adjustable-rate mortgage (ARM) work?

Context

ARMs can be attractive for a lower initial rate, but the structure differs meaningfully from a fixed-rate loan.

The short answer

An ARM has a fixed rate for an initial period (for example 5, 7, or 10 years), then adjusts periodically based on an index (commonly SOFR) plus a margin, within rate caps.

Things to keep in mind

ARMs can start lower than fixed rates but carry future-adjustment risk; they can fit shorter time horizons better than long-term ones.
