<prompt> Human: Ive received a windfall recently and have been spending a fair amount of time researching here about how to best handle it. Emergency fund already set up for 6mos. Roth IRAs already maxed. Only debt we have is the house and my wifes remaining student loans. Her interest rate is 3.78I could wipe out the student loan entirely, or invest it hoping to get a better than 3.78 return. Thoughts?  <response>: As someone who ran into almost the same scenario last year windfall, leading to the choice of invest vs. wipe out student loans, I chose to wipe the loans, and I dont regret it one bit. The psychology of not having that payment every month is quite liberating.That, and you never know what the market is going to do. Had I invested that windfall as soon as I got it, it wouldve lost 10 practically the next day, and would only now be roughly recovering, but thats of course anecdotaltiming the market and should be taken with a grain of salt.
