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.
Research. You need to know what others are selling before you decide what wares you will offer. Lots of people sell handmade items, but those who work hard to make their items unique in some way are the ones who truly stand out. After you’ve decided on a product, check out the other sellers on Etsy and find what they’re offering, and then figure out how you can do it differently.
