Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
Yet another Amazon service providing the possibility to make money online is the Audiobook Creation Exchange. You can create a standalone audiobook, or create an audio version of your eBook as complementary media. And you can narrate your audiobook yourself, or Amazon can put you in contact with a professional to help. Once sold, you can then earn up to 40% royalties per audiobook.
