This is a good question Kijahn ! I have honestly never found a Airbnb listing that was performing at the top of its game. If I did that host probably dosent need help. Unless a host is already a 5 star Super host with 100 % booking rate then there is always room for improvement and to drive more income for the host. The goal here when pitching to a Host is with your skill set the host will generally make more money at the end of the year after they pay you compared to if they were running the business all in their own. This happens because you will provide them optimal customer care, listing optimization via pricing and calander management, you will provide them with high quality photos and will manage the listing in a manner that generates 5 star reviews and these reviews are the back bone of this industry. You also can pitch to a host that by using you as a co-host they can focuse on other aspects of life like family or new business ideas :)
