Hi Carl,
Thank you so much for taking the time to respond. I'm sorry but I should have explained things more clearly. My property is not in the states, but in a country in the EU, so the Airbnb income is generated abroad. Regarding the shop on the ground floor, I rent out the space personally (not through a business structure). The space is occupied by a long term tenant who has been there for years, and I do not provide anything aside from a broadband connection. But you're absolutely right about so many things and I ought to seek out a professional that specializes in US expat taxes. Many thanks again for taking the time to explain things to me!
