Co-hosting means managing a short-term rental listing on behalf of another owner in exchange for a percentage of the booking revenue, typically 15% to 25% depending on how much of the work you handle. Tasks can include guest communication, calendar and pricing management, cleaning coordination and maintenance. To get started, identify owners in your area who are already listing or considering it, offer to manage one listing at a reduced rate initially, and build a track record from there. Clear written agreements covering fees, responsibilities and notice periods are essential from the outset.
