A good list of questions to ask prospective guests was developed by @Queenie0.
Here are some questions you could ask:
(1) What brings you to my area (eg what is your purpose for visiting this area)
(2) What attracted you to my listing? (this can help clarify for instance if they just wanted to get a cheap or conveniently located place, or they liked something in particular about your house)
(3) How do you plan to spend your time during your visit? (You may want a guest who isn't going to be at your house 24/7)
(4) What hours of the day do you plant to be at my house?
(5) What are your waking hours?
(6) Have you read my house rules and do you have any questions about them?
(7) Have you used Airbnb before? (If they say yes, you can ask them how that went)
(8) Have you stayed in someone else's home before? ( This helps make the point that they are in fact staying at someone's home,not at a hotel, a misunderstanding that some guests have).
(9) WHere do you currently reside and what is your occupation?
(10) What are the full names and contact info for all those on the reservation?
I don't use Verified ID, because I have found it creates roadblocks and obstacles to some guests being able to book. One guest was unable to provide the needed info and couldn't book. Another said it took her 6 hours to book my place, to get verified ID set up and then book. SHe said she almost gave up, it was so hard for her. So, I prefer to do my own screening of guests. However, Verified ID is particularly useful if you rent out a whole apartment/home and won't be there during the guest's stay, as it provides another level of potential security, in case something goes wrong.
