Frequently Asked Questions
Will I be penalized for paying off my mortgage early?
Most modern mortgages don't have prepayment penalties. Check your loan documents or ask your lender. Even with a small penalty, the interest savings usually far exceed any fees.
When is the best time to start making extra principal payments?
The sooner the better! Early in your loan, most of your payment goes to interest. Extra principal payments early on have the biggest impact on total interest saved.
Should I pay off my mortgage early or invest the money?
It depends on your risk tolerance and mortgage rate. If your mortgage rate is 6%+, paying it off is a guaranteed return. Compare to expected investment returns and consider tax implications.
