Refinancing
Replacing an existing loan with a new one at different terms — usually to lower the rate, the payment, or the payoff time.
Refinancing replaces an existing loan with a brand-new one — new rate, new term, new closing costs — that pays off the old balance. People refinance mortgages to capture a lower rate, to shorten or lengthen the term, to switch between adjustable and fixed rates, or to pull cash out against home equity.
The decision has one honest test: the break-even point. Refinancing costs real money up front (typically 2–6% of the loan); dividing those costs by the monthly payment savings tells you how many months until the refi pays for itself. Sell or refinance again before break-even and the deal lost money regardless of the shiny new rate.
The classic trap is the term reset. Seven years into a 30-year loan, refinancing into a fresh 30-year stretches the remaining balance over 30 more years — the payment falls, but lifetime interest can rise even at a lower rate. Comparing remaining-interest-if-you-stay against total-interest-on-the-new-loan (plus costs) catches it; matching the new term to your remaining years avoids it entirely.
“No-closing-cost” offers relocate the fee into a higher rate rather than deleting it. Run any offer through the refinance calculator — break-even, monthly savings, and the lifetime verdict, side by side.
