16. Rent Out Your Parking Spot
Parking spaces are prime real estate in big cities like New York or Chicago, and you can earn a good income if you have one to rent. Use Craigslist to list your spot for hundreds of dollars a month.
Have a driveway that sits empty? You can rent that out, too.
17. Rent Out Your Automobile
If you hardly use your car or are heading out of town for a period of time, renting out your vehicle is an easy way to make some extra cash. Apps like Turo and Getaround connect car owners to renters in their cities. Peer-to-peer car sharing is priced per vehicle on a per-day or per-hour basis.
