    "The neighborhood has potential. It’s close to transit and shopping. The homes are nice sized. The garages are too small for an auto to fit in and are mainly used for storage. People just don’t clean their properties as they should. There is often trash and debris along with animal feces from pet owners that don’t pick up. That reflects on the neighborhood negatively."

    "To many vagrants. And it’s like I’m at the United nation. Neighbors are not friendly at all. It’s right next to west Philly a bad bad part of Philadelphia. Mostly every homeowner the was here when I bought my house have moved out or are in the process of doing so. Maybe some day Upper Darby will be great again until that day it is a terrible place."
