There are many things to take into consideration, All of us host have our different ways of doing things as you will learn, Please do participate in the CC there are people here with a wealth of information,
As a host you take a chance with every guest, it's up to you how you judge it, a couple of months back we had a guest who had one really bad review the rest were good, we let him book he turned out really good and he booked again.
You will learn there are Red flags, We never do self check in we always meet the guest, Thats where a lot of trouble stems from, and a lot of guest like how we meet them, with some if they need help getting here i offer a luxury minivan service, they love it.
We dont do one nights stays, we live on a party island, what I mean a guest wants to book a high end pool villa for one night you know whats happening.
All little things but can add up,
