My big picture view is that metros reach a 'critical mass' point where they can attract the 'right' kind of intellectual capital and human resources (workers etc) that build the base of a solid regional economy. 

Do you have any pictures you could post?

Luckily, I haven't been in the situation yet, hopefully never, but here are a few things I'd do to make sure you have backup:1) Written statements from all exterminator companies, along with the bill, and showing how long it took you to respond, and get them in there2)  Written statements and pictures, from all 4 other tenants, showing the quality of apartment3)  Print off all correspondence,  specifically noting when the tenant showed the issue was resolved4)  Proof of payments-- showing she continually paid rent5) If you haven't already, or if she hasn't move, I'd write her a letter,  stating if she doesn't like the place, since she hasn't signed a lease, it's M2M, that she is free to leave next month at no charge.    

If you would like to see pictures I can take some tonight and post later.

We hope that you have a fantastic stay.If you have questions prior to or during your stay please feel free to ask.The day of booking I need to receive a copy of your driver’s license Scan or take a picture.

Tell her you saw on her Facebook page pictures including several dogs. 

Yes I run a complete analysis on every property and a "high end" estimate of rehab based on pictures included online to be safe along with a safe profit to cover budget overuns or lower ARV than calculated.

Not sure if this will be of any help but here is an aerial of the property (the pool is pictured in the bottom left):Thoughts?

If it has some normal damage ( nail or screw holes from hanging pictures) it can easily be repaired.

Mainly I was trying to get a full picture from those with experience to make sure I was on the right track.
