@Wendy214 , I hear you. So most of us hosts don't really feel safe with Airbnb, even if we have a security deposit in place, never knowing if they would actually honor it when an incident arises.
On the other hand, when I travel as an Airbnb guest, I do like the idea that the security deposit is not actively taken out of my account by Airbnb at the time of booking: Just recently I had booked a place, total was something like $450 for two nights, fine. If I had booked the same plave at vrbo, it would have been slightly higher, AND they would have taken the $500 security deposit out of my account right then, bringing that booking to over $1000. Most people, including me, simply can't afford to have that kind of chunk taken out of our accounts, even if it is temporary: my trip goes on to other places, so if each 2 night stay I book requires something like that of me, how can a plan and book a 2 weeks trip?? So as a guest, I take Airbnb iver those otger places!
And keep in mind that, at least here in the US, yes, hotels might put a hold on your credit card for incidentals, but they do NOT actively take the money out. so that is pretty much what Airbnb does. Just something to consider from the guest's perspective, which would make them favor Airbnb over the other sites - and us hosts would benefit from that with bookings.
