Hi Chika, I am late on the scene here but I have just had a week away with friends and this is my first post back on the forum!
Sorry to hear about your damage...unfortunately sooner or later we all strike one, but don't be too disheartened, I have only struck one in 110+ hostings and I think I have learned enough not to strike another in future!
As far as your lack of bookings is concerned I notice you are not using Instant Book! Now in areas where there are not a lot of listings, profile visibility as far as search rankings goes remains good, but in an area like London preference in search rankings is given to those hosts who use Instant Book, and what is happening to your listing, it is slipping down the search rankings to the point where nobody is seeing it any more. It sometimes help lift your visibility if you refresh your page every now and then.....put in another photo or two, change a house rule! Or get some friends to submit enquiries (not booking requests) via the 'Contact Host' tab on your profile. The search ranking algorithm responds to activity, and the more activity you have on your listing page the higher you will rise in search rankings. Because you do not have a lot of hosting experience it may not perhaps be wise to enable 'Instant Book' until you understand fully how it works but, that would certainly gain you a much higher profile.
And finally, as far as setting a security deposit is concerned....this is how you do it!
This is from the official rules guide Chika!
All the best, and don't get too despondent...hosting with Airbnb is one of the best things I have done!
Cheers.....Rob
