Showing occupied property during Covid - when physical walk thru?

[S Harper]

I have a tenant moving and will be posting the property with extensive description and pics from the last vacancy. 
I am thinking of filming a walk through to provide when someone asks to see the property, but at what point are you having a physical walk through? It seems unlikely that they will want to wait until after they apply and I know that they qualify/are serious. Having someone walk through and tell me that they wanted something completely different - ex. with an en suite - after they have seen all of the pictures and descriptions was enough of a pain before the elevated health concerns was bad enough (and for some reason I get a lot of that with this little 1970s house every time it's on the market). 

If you are doing video tours - are you just doing Facetime? Or something more like Zoom? 

Thanks for your input!
