@Jason1735 I would take the "screening" with a grain of salt. There have been reports on this forum in the past by hosts who signed up for open homes and got scammers who weren't disaster victims at all. When hosts offered homes for essential medical personnel near the beginning of the pandemic, some hosts reported getting doctors who in fact arrived with their entire families and basically were vacationing, not treating Covid patients.
As an aside, providing tax info to Airbnb has nothing to do with owning the home you are listing. There are plenty of hosts who don't own the homes they list. The tax info is required so any earnings are taxed correctly. But if you are offering the space at no charge, you won't be earning anything to be taxed on.
