I've since increased rent, screened for better tenants and I'm currently hacking the other side.

SEC 8 requires screens and handrails, and really should should provide them for any tenant, so you should really consider that this was an accidental omission of your rehab.

Instead they have a close up of screen doors with bars on them.  

Great Idea to help keep up the unit it top order and avoid those unnecessary maintenance calls.

With so many different tenant screening services how do you guys choose who to use?

Things like screening tenant's, property management, and running the numbers to find deals. we want to be clear in our description so there will be no confusion on who should be doing what. 

The new TV's we have today (computer monitors too) actually use a lot less electricity than the old CRT screens did.

The type of work I typically do for investors can range from taking inbound lead calls and screening them based on criteria put forth by the investor, creating searchable databases with homeowner and property information from lists provided by the investor, setting up appointments with potential leads based on my clients schedule, and searching for potential deals in my clients target area.

Upwork records their screen periodically while they're working.

OST3 (On screen takeoff 3) is a good one, but requires plans to use properly.
