In a guess....eventually, but we're talking 8+ years out. It's going to take a major player to move in to make something happen. That area is rough.

Edit to add: I grew up in East Passyunk in the 90s/2000s. It's always been shady, but has been extremely so in the last decade or so. My analysis is based on a few things. I was looking to buy a house and had been out of the area a few years, so figured why not. Every property needed extensive work. Like absolute gut jobs. I visited two properties that had been worked on - both had been broken into. The first was trashed, the second we didn't investigate because it was clear someone was already in the building with us and we noped out. The level of dilapidation there coupled with poverty makes it hard to maintain these properties, and the safety issues are a deterrent as well, especially when there are safer areas to move to that aren't ridonkulously overpriced. It's gonna be one of the last sections of South Philly to see change.
