Refusing a Tenant Prospect Before Showing/Application

[Fareen E.]

Hi, question:

May I tell a prospective tenant he's not a good fit before showing the house to him because he's refusing to comply with my showing policy of sharing a copy of his ID with me prior to the showing? He's from Facebook. I do have a lot of interest in the home and it will rent soon. But this guy gives me the indication he will be difficult.

Note: as a realtor, I’m already used to this as a safety measure. 

Thanks in advance
