In regard to items blocking defects (furniture hiding a hole in the wall for instance). 

I also grew up pretty poor in a town run by a major gang (shout out Fresno, California), so I have a strong functioning understanding of "rough" sides of town -- I know when a street is run by a gang, or when it's just a bunch of poor but wholesome families trying to get through their day, and how that can change from block to block.

It’s 2 blocks from city hall and the police station. 

If that is not the description, then you probably have a D area (where there's a boarded up building in every block or every other block). 

Sometimes even one block can make a huge difference.

The area is about 2 blocks from the incoming Worcester Red Sox stadium coming in.

One block is run down, the next is Class B+, then back to C and back to B+ with some A class spots sprinkled in.

As you probably already know, Philly is a block by block city, and the Elmwood section certainly confirms this.

Rehab projects will run into stumbling blocks despite your best efforts.

I've also had luck during the week from the 6:00pm-8:00pm block.
