Appraisal/Appraised Value: An opinion of the market value of a home expressed by a real estate appraiser.

Arbitration: The term used to describe a form of dispute resolution that occurs outside of the court system.

Caps: Provisions of an ARM limiting how much the interest rate can change at each adjustment period (e.g., every six months, once a year) or over the life of the loan (rate cap). A payment cap limits how much the payment due on the loan can increase or decrease.
