CHARM Booklet

by | May 15, 2026

The Consumer Handbook on Adjustable-Rate Mortgages (“CHARM Booklet”) is a consumer disclosure document developed by federal regulatory agencies to help borrowers understand adjustable-rate mortgage (“ARM”) loans and the risks associated with them. Mortgage lenders are generally required to provide the CHARM Booklet to consumers when they apply for an ARM loan. The booklet explains how ARMs work, including how interest rates may change over time, how those changes can affect monthly payments, and the meaning of important loan terms such as adjustment periods, index rates, margins, rate caps, and payment caps. Its purpose is to ensure that consumers receive clear educational information that allows them to make informed borrowing decisions before entering into an adjustable-rate mortgage transaction.

For Mortgage Loan Originators (“MLOs”), the CHARM Booklet is significant because providing the booklet is part of the federal disclosure requirements associated with ARM loan applications under Regulation Z and related consumer protection laws. MLOs must ensure that borrowers receive the booklet within required timeframes and understand the general features and potential risks of adjustable-rate financing. Proper delivery of the CHARM Booklet helps promote transparency and consumer awareness, particularly regarding the possibility of future payment increases and interest rate adjustments. Failure to provide required disclosures, including the CHARM Booklet when applicable, may result in compliance violations, regulatory penalties, and increased legal or reputational risk for mortgage professionals and lending institutions.
