How Refinancing Actually Works

A refinance replaces your existing mortgage with a new one - often with a different balance, amortization, lender, or rate. Homeowners refinance to consolidate debt, access equity, restructure payments, or fund major life expenses.

Before any refinance, the first calculation is the prepayment penalty on the existing mortgage. With fixed-rate mortgages this can be substantial; with variable, it is typically three months' interest. Without that number, you cannot evaluate whether a refinance makes sense.

Done well, refinancing is a strategic reset. Done poorly, it simply extends amortization without addressing the underlying issue. The numbers matter - and they need to be honest.
