Adjustable-Rate Mortgage Options

Unlike a fixed-rate mortgage, an ARM can change after its initial period. The loan documents identify the index, margin, adjustment schedule, caps, and any floor.

The initial ARM rate may be different from a fixed-rate option, but a lower initial rate is not guaranteed. Compare verified terms for the same complete scenario.

Review the highest possible payment and do not rely on a future sale or refinance to avoid an adjustment.

Adjustable-rate mortgage FAQs

An ARM has an initial interest-rate period and can then adjust on a schedule stated in the loan documents. After the initial period, the rate generally uses a specified index plus a lender-set margin, subject to the loan’s adjustment caps.
