It was predominantly the collapse of the car-dependent suburban fringe that caused the mortgage collapse.
In the late 1990s, high-end outer suburbs contained most of the expensive housing in the United States, as measured by price per square foot, according to data I analyzed from the Zillow real estate database. Today, the most expensive housing is in the high-density, pedestrian-friendly neighborhoods of the center city and inner suburbs. Some of the most expensive neighborhoods in their metropolitan areas are Capitol Hill in Seattle; Virginia Highland in Atlanta; German Village in Columbus, Ohio, and Logan Circle in Washington. Considered slums as recently as 30 years ago, they have been transformed by gentrification.
Simply put, there has been a profound structural shift — a reversal of what took place in the 1950s, when drivable suburbs boomed and flourished as center cities emptied and withered.
