I would likely first get a trustworthy financial advisor to help manage my funds. If we aren't counting tax and are assuming that we don't have to pay any other sort of fund to get the $1M then I would immediately invest 500k into specific stocks that I believe will end up becoming great investments (this would likely take weeks of planning and watching different stocks). I would then use around 350k paying off the rest of my house and my car as well as my remaining college debt. I would have 150k left after this which I would add to my savings for future issues, I could also use some of it to pay off a year of expenses. I wouldn't pay a cent on anything that isn't necessary as if I payed off a year of expenses I would have the remaining portion of my regular paycheck to spend on myself.
