I also want to point out that I'm sure everyone on this forum wants well built good looking structures in the city.
My only objection to survivor bias on these properties is the fact that they have many problems, and some even deadly.
I see comments saying nothing is better about new construction, lets put aside the fact that there will never be stone or brick townhomes built in that Manner like they did in the past without a lot of money going into the project, new construction brings everything to updated standards, No asbestos, no lead, no dust or gas issues in the basements, the layouts of homes are better and built to suit todays people.
I lived in, and fixed up a circa 1945 home in Oxford circle off the blvd last year, now while the home wasn't as old as many of the rowhomes in Philly and actually the last generation of rowhomes really. it had issues that cannot be addressed by a rehab, rooms were an ok size and lacking actually closets, outlets are sparse unless more are added, the living and kitchen area were ok, its only so much you can do with a rectangle, 1 bathroom in the house which in todays standards with a family is an issue, and the basement was not habitable it would have to have a full rehab and it wasn't even finished, the basements of that time were not meant to have people living in them and even with a rehab you'll have issues because it was more of a storage/celler compared to a living basement. The only plus with that property would be an alley and 2 car parking spots in the back which 95% of homes in Philadelphia do not have.
I am for saving structures and promoting history as much as the next person, but you're not gonna tell me that a home from 1800-1945 fits the need of people today.
Seriously look at these two properties
New
Old
