Its possible she sees some kind of weakness there for her to exploit and is testing the waters of what she can get. 

Running water/w showers, toilets, fire pit, sounds like fishing is possible....  

There are water stains in the ceiling, the electric needs some help in the floor two bathroom, as well as the water pressure in the shower.

We saw this happening a little bit a few years ago when many properties were getting multiple offers, but the market has been cooling rapidly to more of a buyers market lately (in my location at least YMMV).

Quote from @Taylor Waters: Hi all, I spoke with an investor via phone that I met through Reddit.

The tenant failed to mention that that was the time they were going to be filming a "home movie" in the water bed.

First invested a solid chunk of money into a flipping mentorship, listened to every BP Rookie episode ever made, more podcasts, more books, more phone calls, and finally landed a really cool position working for an investor in my area.

Lucky for you, I am knowledgable on military & investor related topics and its cool that this is a hybrid question.

I believe that the shower in the second floor bathroom is causing water damage and creating the mold in the first floor bathroom ceiling, which may require removing the first floor bathroom ceiling. 

You can lead a horse to water but you can't make him drink.Just my 2 cents.
