1 - If you are new, then Airbnb sets up an initial discount yo promote your listing.
2 - Check your settings, calendar day by day and every setting
3 - Search monthly stays on this site, there are many nasty stories.
4 - Especially, keep in mind tenancy/squatter rights.
5 - Does your commercial insurance cover long term stays?
6 - Unless a home share, home insurance generally does not cover STR'S.
Personally, we do not STR beyond 14 days.
