What would you do in this situation?

[Paul Farley]

I am not into real estate yet. I am still doing research. I am also a beginner in investing. I have some small investment accounts.

I have 30k in student loan debts, a car loan and mortgage.

If you had 40k to either invest or pay off debt, what would you do? I am leaning towards investing so that I can pay back my debt faster than I would otherwise and be able to increase my income. 

Though, with 40k I'm not sure what the best option for an investment (whether real estate or other types of investments). I just purchased a home so getting another loan is pretty much out of the picture right now. 

What would you do in my circumstance?
