I had a similar discussion a while back and this is what was thrown around...If the property has some feature that "offends the senses" of the appraisor it is possible to get a lower appraisal due to a common trait among humans...

People are human and if they can find a house for 100 to 200 less in the same area, they're going to move.

I googled for ready-mix concrete services in my area which is Belleville - Bloomfield New Jersey but found only a couple of bigger companies with price fork 350-480 $/y3, I also tried to lookup Angieslist but still nothing..I wonder if there're smaller contractors with more human prices?

Don't forget your local Habitat For Humanity Store if you have one.  

The one thing we can control as human beings is our effort.

To get rid of things, we use Habitat for Humanity.

Think drug dealers or human trafficking, etc.

It certainly looks like it houses a wealth of information and resources... including human resources! 

I realized that we are all connected, and when I do something no matter if it's positive or negative it leaves ripples that every human being can feel.

That being said, just like humans dogs each have their own personalities and they're all different so no guarantees.
