Update: I went back in the fall of 2021 and January of 2023 (last four photos).
I took a look around Wells-Goodfellow to see how things were doing. I had been back in 2018 to revisit places I had seen in the past, and things were looking much the same as when I had looked at the neighborhood in extensus in 2017. The Leschen Wire Works are supposed to be renovated into a medical marijuana dispensary, but I saw no evidence of renovations beginning yet.
I revisited the street again in July of 2023.
I went by the four-families I had seen years ago, and while they are still standing, they are all still abandoned, and the underbrush is starting to grow up after the March rains.
