Good to know

Extra mortgage payment questions Southern California homeowners actually ask.
What does an extra mortgage payment estimate show?

It estimates how much interest you might save and how much sooner the loan could be paid off if you add extra principal payments.

Can I change the extra payment amount?

Yes. Change the monthly extra payment, one-time payment, and start month to see how the payoff estimate changes.

Why compare this before paying extra?

Paying extra can be smart, but it also ties up cash. The right choice depends on your rate, cash reserves, other debts, and how long you plan to keep the home.

What should I verify?

Check whether your loan has prepayment rules, how your servicer applies extra payments, whether escrow changes, and whether the cash has a better use elsewhere.
