My college major was Church ministry: youth ministry which is pretty unrelated to sales for the most part, but I am confidently able to plan events, teach/speak in front of crowds, and create event calendars/documents/liability forms.

It's tenants that react like this that add some fun to being a landlord assuming of course you know what you are doing and are fully prepared for court.Make sure you document everything.

Are you other guys able to view the .jpeg document above or is it just Mark?

The autosave feature is great, and you can access the document from wherever you happen to be. 

Have a property inspection inside and outside performed and documented and start eviction immediately according to the steps outlined in the VA state statues.

If I refuse to rent to people like Billy in the future, how do I legally document when I feel like someone doesn't have the ability to take care of a property?

Provide both documents to your closing attorney.

Make sure you retain these documents and you should be fine.
