What is a lifetime adjustment cap?

A lifetime adjustment cap is the maximum total increase — or decrease — that an Adjustable-Rate Mortgage's interest rate can undergo over the entire life of the loan, regardless of how much the underlying index moves. It acts as a ceiling and a floor on how extreme your rate can become. For example, if you start with a 5% rate and your loan has a lifetime cap of 5%, your rate can never exceed 10%, even if the index rises dramatically.

The lifetime adjustment cap is a critical piece of information to obtain and understand when evaluating any ARM product. It allows you to calculate a worst-case payment scenario and decide whether that payment would still be manageable. Buyers in the Western Catskills financing vacation properties or investment homes in Delaware, Greene, Ulster, or Otsego counties on ARM products should run this worst-case calculation before committing — particularly if the property's rental income is intended to help service the debt, as rental revenues can be unpredictable.
