<prompt> Human: I am four years into a 15 year mortgage at a 3.375 interest rate. My wife recently read Dave Ramseys total money makeover and is very excited about trying to get all of our debts paid off. I am too.We could pay the entire mortgage off in the next 5 years, by paying around two grand a month more than our minimum payment, or we could invest that amount in a taxable investment account.We already have a solid emergency fund, are already maxing Roth IRA and 401K, and are contributing to a 529 for our daughter at the amount we think is necessary. So, this is really about whether it is better to invest this roughly 24K a year in a taxable investment account, or pay the mortgage off. If we pay the mortgage off early, we will be in a position to begin contributing 4K month to an investment account in roughly five years, whereas if we pay the minimums on the mortgage, it will be a closer to ten years, but we will have ten years of beating the interest rate to show for it.I guess this is the classic guaranteed 3.375 vs. gambling you will get 5-6 after taxes question. Just curious what the groups thoughts are.Thanks in advance.  <response>: I would hedge both, and go with 1kmo investment, 1kmo extra payment.
