I'm concerned that doing so could be perceived as a threat, violation of privacy, and turn-off a prospective lead.

Quote from Rhett the Threat: One way I find that owners have success in this is through their property manager. 

I also had a lot of the height removed to make it less of a hurricane threat, even tough at its highest height it wasn't much of a threat anyway.

I would tell everyone, including the Tenant and the person you are showing the property to, that you will record audio of the showing for personal protection due to threats made by the Tenant.

Never accept ultimatums or threats.

Notify law enforcement of the threats.

Really explore the fraud angle, he very well may have done something criminal and threat of jail time usually stops the games.

As far as the STR issue - I would not want to offer that if the threat of someone from zoning may show up at the door and disturb renters.

As it is DOS is dangled out there as a sort of vague threat, which of course is counter to the banks actual financial interests.  

Anyway, hoping someone might be able to give me a little insight into the reality of the tornado threat…or even the harsh winter conditions...
