But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
More than half a billion products are sold on Amazon every month, making it an incredible opportunity to make money online. But, like everything else that involves making money online, you have to do quite a bit of work to earn it. One option on Amazon is to find products that are already made and buy and sell them at a discount. For example, you could research generic products such as clocks, keychains and mugs to attach to your brand.

However, watch out for scams; check the MSPA for a list of legitimate mystery shopping companies. Earning potential: About $10 per hour
It’s one of the oldest and most proven ways to make money – buy low, sell high. The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new. In this way, you might be able to acquire an item for $5, and later sell it for $50.
