I am in pretty much exactly the same position. We last visited our property in February, and planned to go again in March, but that didn’t work.
Luckily I pay everything remotely and we have friends who look in from time to time to make sure the air conditioning is running and so on. There is not much else to do, at the moment. I have considered quarantining in Canada for 14 days to have access, and I may have to do that. But to be honest, people in Florida (and other states) don’t seem to take this very seriously, so I’m not sure I want to be there!
