How to conduct background check on mid term Airbnb guests and who pays for it

[Jin Zhang]

Hi everyone, 

I just started doing MTR on Airbnb. I have written in my rules about background check and sign a lease. I have a few groups approached and all confirmed understanding the rule. I ask them not to book since there is cancellation penalty for hosts. I want to vest them before booking. But once it reaches the stage of background check, they disappear. It seems like that they do not want to pay for the 45 dollars to go through it. Have you run into this before? Do you ask for background check? If so, do you pay for it or the guests pay for it? 

Any input would be greatly appreciated! Thanks!
