I am not familiar with Philly or the technical questions you pose.I am thinking of this from a purely investment aspect.  

If i were to be a billionaire, i wouldnt mind to put 1 mio in a pure speculative bet.

The time before I think I found a suitable replacement building purely by luck.

i helped my clients gettign 200 homes purely section 8 lease in dallas area. let me know if you want to invest in dallas area.

I understand that isn't what you thought initially but 15k is insane to get what you got and ended up with.There is way to much social med. crap that "get rich quick" is a pure and total smoke screen regarding real estate.

They stink - pure and simple. 

If you had a negative experience directly that would be one thing, but anything else is purely speculation from the outside looking in. 

It isn't much yearly for a pure investment property.What will it bring in as a LTR?

IT OWNS ONE OTHER PROPERTY THAT IS PURELY AN INVESTMENT PROPERTY THAT WE NEVER LIVED IN. 

House hacking and buying a pure rental are very different strategies.
