Airbnb
Many people have spare rooms in their homes or even own a second property. Instead of allowing it to stay empty, they could rent it to tourists. This is one of the best side hustles because it can be very lucrative. It’s important to keep the premises clean to ensure a welcoming environment for guests.

Remember that some jurisdictions ban Airbnb completely or restrict it. This opportunity may not be available to everybody but it’s worth thinking about. If somebody’s child goes to college and moves out, then think about turning their room into a financial resource. Don’t forget that ratings are everything in this world (via The Real Deal).
