Make money? Here's how:
1. Rent out stuff you already own. This way, you don't need a capital because you are going to make money from stuff found inside your house.
2. Now you dont need to have a specific item to rent out. Simply identify which items you are open to letting other use.
3. Look for a platform that will let you sign up for free, put your rentals on hundreds of users and provide you an item insurance.
Why this works? People will always look for ways to save money. That's why they turn to renting instead of buying at full price.
This is called the Sharing Economy. An example? Airbnb. Uber. And a lot more. If I may suggest a platform, I'd put my best on
My Garage Rentals. They're free and they show my items to people near me. I earn through my things.
