Hi Denni,
To become a co-host, update your Airbnb profile to highlight your passion and skills, then connect with hosts through the Airbnb Community Center, social media groups, or local events. Offer to shadow an experienced host or help friends manage their listings to gain experience. Use Airbnb resources like the Host Academy to learn best practices.
Build your reputation by letting the community know your target location/s, tracking successes, such as improved guest ratings if you already have a listing, and gradually expanding your portfolio.
I hope this helps.
All the best,
Upfish Management
