The worst ones usually don't have any clear cut guidelines (a lot of the underwriters will make up their own rules if they do not like the deal), Suck at communicating (will reply days later), Push aggressive terms to get deals in and then switch them, and Not really motivated to get things done (they will adverse a loan without any hesitation). 

Specifically asking about public safety, appreciation vs. cash flow thoughts, and complexity of building a local team (agent, property manager, general contractor).

After you find the list, are investors directly contacting the owners to cut a deal and buy the home before the tax sale?

If the sample(s) that tested over the threshold were from under a window (which is the norm), you probably need to address the window frame/sill and I'd recommend just cutting to the chase and painting them. 

If you want more affordability, CUT programs, CUT tax's, REDUCE centralization. 

I was initially told there was an HOA but eventually found out it's not active and there's a lady who lives somewhere on the street that pays a lawn company to cut and trim everyone's yard. 

Also, indicate any safety nets, such as a solid W-2 income.

This is such a safety hazard it's not even funny!

Many cities allow short-term rentals of primary residences as long as certain conditions are met, such as obtaining a business license and meeting safety requirements.
