I believe it actually suggested you buy your own camera and learn how to use it, but it just skimmed over making sure people are out of the pictures, etc. 

Though it’s tempting to take pictures on your device — smartphone cameras are becoming undeniably sharp — use a professional camera or hire a professional.#2: Soft Skills - If your soft skills could use improvement, start working those muscles now.

There is an app called Canvas.io that can be Downloaded to an iPad or iPhone (they need the latest cameras) and you can scan each unit.

My tenants installed security cameras everywhere inside/outside.

There are a million potential problems that could exist that cameras and photos don't pick up, and that your agent and inspector may or may not convey to you (e.g.; old galvanized steel plumbing, asbestos, foundation settling, proximity to busy and loud highways, deadbeat neighbors who don't maintain their property, proximity to bad neighborhoods, signs that the HOA isn't maintaining the area and other signs that the HOA is incompetent or not functioning properly, etc., etc., etc.).

The tenant could also invest in a security camera or two, that would probably be cheaper. good luck. 

I see on security camera that she still has some things in her storage spot.

I have a $300 HD 360-degree camera that takes fantastic pictures and video.

I use Schlage encode to issue door lock codes and have a ring camera.  

Curb appeal, lighting, possibly security cameras, solid core or decorative metal doors with deadbolts and security screen doors, interior painting that is not one color on everything, accent walls in main living area and primary bedroom, cabinets and closets painted white on the interior, flooring limited to one or two designs throughout the unit, and no carpet, windows and screens fully operable and clean...all of this will elevate your unit vs. most of the others in such a neighborhood.
