Q1: How much can I save with extra payments?
A: Depending on your loan terms, extra payments can save 10-30% of total interest and reduce your loan term by several years.
Q2: Should I make extra payments or invest?
A: This depends on your interest rate vs. expected investment returns. Generally, if your mortgage rate is higher than expected investment returns, pay down the mortgage first.
Q3: Are there penalties for extra payments?
A: Most US mortgages allow extra payments without penalty, but check your loan terms as some may have restrictions.
Q4: Is it better to make one large extra payment or smaller regular ones?
A: Smaller regular payments have a slightly greater impact as they reduce principal sooner, but the difference is minimal.
Q5: How do I ensure my extra payment goes to principal?
A: Specify with your lender that the payment should be applied to principal, as some may default to applying it to future payments.
