I have personally come across this problem a few times. Recently as well.
ABNB doesn't actually take a security deposit for you. Even if you request it. Nor
will they allow you to take one either. When you come across this problem
with guests not respecting your property, and or not following the rules, you basically
get someone from ABNB to handle it for you, and they are not host friendly.
They will 9 out of 10 times side with the guest. They also expect you to jump through hoops, prove
everything your saying with 48 hours of reporting. There are certain things they won't even
consider as proof. Basically it's a real pain. I advertize on other sites where I'm in control.
I can send a agreement out to be signed, and collect a refundable damage deposit.
I have found that ABNB guests are far more careless because of this.
