If you want to start a cohosting business @Ash5000 start by doing your market research.
Who are your competitors?
What can you offer that is different/better than your competitors?
Have you invested in developing a marketing plan to help you understand how to reach hosts who are your target market. If you want to be a cohost you will need experience of different STR platforms - not just Airbnb.
You also need appropriate insurance, a contract etc.
By the way it's against the terms of this community to use it to advertise commercial services such as cohosting.
