There is already a search criteria for whole house, or shared house but it doesnt show if the host is actually in the shared house. In addition to home-sharers who live on site you'd need to add an in-between, maybe "entire private house with host nearby" I mention being nearby in the description of the property and in my profile. So in essence I could tick either home-sharer or not and both would essentially be correct, as I live in an old church (not shared) but have the quite separate Sunday School building on airbnb, i.e guests still have privacy - so its not just a matter of a push for differentiating home sharers from multi-unit property owners you'd need more choice, eg I am a non-sharer yet across the courtyard if needed. A lot of listings are similar, not really home-share eg "granny flats" in the garden or separate buildings but near the host....Cheers, Judy, The Sunday School, North Hobart, Tasmania, Australia.
