19. RENT OUT PARKING

 If you live in an area where parking is in high demand, and you have your own parking spot, you may be able to earn cash by renting that space out to others! Sites like Neighbor.com and Spothero allow you to rent out parking spaces to people in your area that need parking.

Depending on the location of your parking space, you could potentially earn hundreds of dollars each month by renting out your spot. If your parking space is empty, there’s no reason to let the space go to waste. Rent it out so that you can give someone a place to park and earn extra money!
