Not to change the subject too much but do you have more info on reward.app? I'm trying to learn more about all of these amazing things and I tried entering the url(is it one?) and it's an unhosted domain.
More relevant note- feel you on the BNB thing. I live in a very overpriced area and have been caretaking a condo for the past few years. The only way I could afford it was to live in a small room with a separate entrance and do short term rentals for the rest of the unit. COVID shut that down and now I've been scrambling to pay for it without running the sub-business for the owners. I filled my room with a room mate, so it's not horrible, but I certainly would have not wanted to live here without my rental ability.. tough times for all. Hope you're making it through ok!
