<prompt> Human: I was wondering if you could help me understand the pros and cons when paying off a mortgage early. 30 year fixed at 6 15 years into it Ive been saving until I have enough in savings equivalent to the amount I owe on the mortgageMy financial advisor is telling me that some people wait until the end of the year and then pay an extra big chunk of money -- like 10,000 -- to start to lower the interest I have to pay. Im not sure if mortgages work this way or if that would be of benefit.  <response>: Would you borrow money at 6 interest to go invest in the stock market?Heres a good article about the pros and cons of paying down your mortgage instead of investing. The math behind it can be found in this blog if you are interested in the details.Im not sure why your financial advisor is telling you to wait until the end of the year, you should pay it right now. Perhaps he gets his commission if you hold your investment for that long?Id fire your financial advisor. If you arent paying for a service, you arent the customer, you are the product being sold.
