What is your relationship with the owners @Jc128 - why are you recommending they employ a cohost who's not even in the same time zone.?
the whole point of a cohost is that they are on hand to provide support locally for owners who live remotely, they understand local STR regulations, can do cleaner spot checks and go to a listing to sort out issues with problem guests or for maintenance issues .
how are the cohosts you want to employ who don't live in the US going to be able to do this @Jc128
