<prompt> Human: Background: 27 year old single male with awesome job security US military. I currently owe 20k on a Jeep at 1.4 interest. Grandmas estate was just settled and Im receiving 20k today and another 20k in about a month. I currently dont have an issue making payments to pay off the vehicle in a year and a half before I hopefully start medical school. The vehicle is my only debt and Im maxing out my Roth IRA and contributing over 14k annually to my TSP. What ideas does Reddit have for making more than 1.4 with Grandmas money...or should I just pay off the Jeep?Edit: I dont believe is paying for my own education. The Army paid for my undergrad. I plan on being an Army doctor and having them pay for my med school in exchange for my continued service.  <response>: No. Put the max in a Roth IRA for starters. Put the rest of the money away. You dont really gain anything by paying off a 20k loan at 1.4 that only has 18 months left.
