<prompt> Human: Hi All, quick question. If someone has 110000 in savings. A mortgage of 60000. No other debt. Employed. 40yo. Should they just pay off the mortgage? Doing so would save about 15000 in interest over the remaining 10 years of the loan. Is there a better option? ThanksAssistant: The only other way of thinking is if you invest that 60,000 in say... Stocks, would you be able to get more than 15k to offset the interest that you are paying? I am thinking that is highly poasible. But it really is a gamble.Human: I dont know anything about investing. Interest rate is 4. I think ill go with the gauranteed savings of just paying off. Isnt it all supposed to crash soon?  <response>: This has been one of the longest bull markets in history, but it just illustrates the problem with timing the market. Years ago some people thought they could predict the end of the bull market and a recession because we were due. That would have been a huge mistake to stop investing or move investments to cash. The proven technique is to invest early and often in a diversified low cost portfolio and let compound interest do its work. Whether to pay off the house is a personal decision but keep in mind 60k at an average of 7 over 30 years becomes 456735. You have a range of options that includes extra principal payments.
