The real problem is that the vast number of beginning investors never bother to learn their state landlord tenant codes before they invest.This is my pet peeve with new investors...trying to operate a business requiring knowing the law without having the desire to learn.They should never be allowed near tenants, they need a PM.On the other hand responsible investors that learn the laws first I would strongly advise self managing.

There was one instance discussed in the forums with a syndicator called Norada (you can search the forums for that name) where they not only stopped paying dividends, but also converted everyone’s capital to an equity position - which is code for “We don’t plan to give your money back unless we can survive to eventually sell the building.”  

Hello BP, I wanted some help with what some of the best zip codes and or Neighborhoods to invest in/around Philadelphia?

You likely have codes and code enforcement officers that will start issuing fines for the trash and unkempt yard.Keep filing complaints with the owner and city until it's resolved.

Also, I'd be very careful that tenants not wanting renovations isn't just code for "I don't want you poking around to see what I've done to this place!"
