Quick Facts: Payoff and Liquidity

Reserves first

Home equity is harder to access than cash.

Extra principal can reduce debt and future interest. It also moves cash into home equity. Build the strategy around reserves and competing priorities, rather than the payoff date alone.

Extra mortgage principal

Reduces the outstanding balance and interest charged. It generally does not lower the required monthly P&I payment; a recast, refinance or other arrangement would need separate review.

Accessible reserves

Keep cash available for a loss of income, repairs or other needs. Access to home equity may require selling or qualifying for new credit.

What an extra $500 can change

Fixed rate, timely payments and no fees or prepayment penalty. The final payment is partial. Taxes, insurance, ownership costs and any investment returns are excluded. Your loan’s terms and payment handling apply.

Keep the option to pay later

A separate payoff fund keeps extra savings outside the required mortgage payment. You may later choose a lump-sum payoff, or keep the money available for another need.

Continue required mortgage payments.
Choose an account after reviewing risk, tax and access terms.
Review the fund alongside an updated payoff quote.
Keep the choice to repay or retain the cash.

Savings and investments are not interchangeable. Market losses, taxes or low yields can change the result; a separate fund does not guarantee an earlier payoff or better outcome.
