Replacing an existing mortgage with a new one, usually for a better rate or term.
Refinancing pays off your current mortgage with a new loan, typically to secure a lower interest rate, shorten the term, or tap home equity. Because it involves closing costs, the key question is the break-even point — how many months of payment savings it takes to recover those costs. It pays off only if you keep the loan past that point.
If refinancing costs $6,000 and saves $180 a month, the break-even is about 33 months.
