Frequently Asked Questions

How do extra payments reduce my mortgage?
Extra payments go directly toward your principal balance, reducing the amount you owe faster. This means less interest accrues over time and you pay off your loan sooner.
What's the difference between monthly and bi-weekly?
Bi-weekly payments mean you make half your monthly payment every two weeks. This results in 26 half-payments per year (equal to 13 full payments), effectively making one extra monthly payment annually.
Are there penalties for extra payments?
Most conventional mortgages don't have prepayment penalties. However, check your loan documents or ask your lender to be sure.
How much should I pay extra?
Even small extra payments make a difference. Start with an amount you're comfortable with - $50, $100, or $200 monthly. Use this calculator to see the impact.
