<prompt> Human: I am 55 years old and I have 191,000 left on my mortgage at a 5.250 interest rate. I do not have any retirementnow starting to put money into roth ira and maxing it. I have around 390,000 in liquid assets due to an insurance payout. Should I pay off my mortgage or invest the money in a brokerage account?I am planning on selling the house next year. Even if I am selling the house next year it seems stupid to keep paying the mortgage at this interest rate.  <response>: FYI, a year of 5.25 interest on a 191,000 balance is about 10,000. Selling the house next year could mean anything from January about 850 to December the full 10,000. AprilMay is usually the big real estate season, so figure about 4000, or around 1 of your liquid amount.
