@April161 Obviously no one knows how long this is going to go on. And all hosts are in the same boat. I don't agree that people are cancelling out of pure panic. If we want this virus to stop spreading, people need to stay put, not travel, not sit in planes full of people. This is what the medical and scientific community are telling everyone. It makes total sense. If everyone did that for the next few weeks, it would be over.
You are among the most fortunate people on this planet to be able to afford to have a vacation home apart from your primary residence. That it's costly to maintain isn't anyone else's problem. The hosts I really feel sorry for right now are those who host in their own home and depend on the str income to pay their mortage and put food on the table for themselves and their families. Most of those people not only rent out rooms in their home but also work one or two other jobs to make ends meet.
I'm not unsympathetic to the fact that your rental income, and that of others, has dried up, but if the only way people can afford to own a vacation home is to rent it out when they aren't using it, then I guess they will just have to start living within their means and only own the home they live in. Personally I don't consider that to be a crisis situation.
