How do I back out of this screening process? PTSD

[Jason Butts]

After successfully screening a potential tenant we’ve agreed to show the apartment. 1br 1 bath.

While showing him the apartment and engaging in conversation, he revealed to me that he has 6 children that live with his fiancé and that DCS won’t allow him to live with the children because he has blackouts due to PTSD. The way things work is that my wife does the vetting, and if all goes well I meet the tenant and show the unit. Considering I was standing in front of him, I figured he’d passed all her tests to make it this far. This information was not revealed to her.

He left today with plans to meet with the VA housing authority tomorrow morning. They have a program that pays first 3 months rent plus security deposit for veterans who are trying to get back on there feet. I come from a Naval military family and being able to help a veteran that fought for all of our freedoms definitely felt like something good to do. I verbally told him I'd hold the apartment for 24 hrs or until we hear back from him to be nice. No papers were signed, no lease, no deposit to hold.

My wife has firmly told me to get rid of him. How can I do so legally? What rules do I need to know in this instance?

Thank you in advance. Stay healthy 👍🏻
