Ok... a rental property isn't a small investment. But putting your money in a mutual fund right now isn't a bad idea. The market has dropped significantly, so even if it drops further, it will go back up in the long term.
Alternatively, if you're willing to work, you could try growing veggies/produce on the side, and sell it locally. Where I am, blueberries are a huge thing. People literally park on the shoulder, walk off into the bush, and come out an hour later with buckets of blueberries. Then they sell them.
