Apply your savings

Smart moves that change the math — layer them however you'd actually use the savings.

Apply skipped payments at closing
When you refi, you typically skip 1–2 mortgage payments. Apply that cash to principal.
$
Keep paying your current payment
Apply your old payment to the new loan. Savings go straight to principal each month.
Extra monthly principal
An additional fixed amount above your payment, every month.
$
Shorter loan term
Force a shorter payoff (e.g. 20 or 15 yrs). Monthly goes up; lifetime interest drops.
