Rate Cap

Definition and meaning of Rate Cap in real estate.

A rate cap is a limit on how much the interest rate can increase or decrease on an adjustable-rate mortgage during a specific timeframe or over the life of the loan.

In more detail

These caps protect borrowers from extreme payment shocks when market interest rates rise. Typically, adjustable-rate mortgages feature three distinct types of caps, which are the initial adjustment cap, the periodic adjustment cap, and the lifetime cap. The initial cap limits the first rate change, the periodic cap restricts subsequent adjustments, and the lifetime cap sets the maximum rate the borrower will ever pay.

Understanding these limits helps home buyers budget for the worst-case scenario over the life of their home loan.

Can a rate cap cause my monthly payments to decrease?

Yes, rate caps can also apply to downward adjustments, limiting how much your interest rate and monthly payment can drop during a single adjustment period.
