Break costs are a fee a lender can charge if you exit or change a fixed rate loan before the term ends. They are based on movements in wholesale rates, so they can be large or small, and they are the main reason to time a refinance around your fixed term.
Written by Ross McFarlane, Licensed Mortgage Broker (Credit Representative 526725).
