Michael Galdi, an agent for Century 21 Advantage Gold in Philadelphia, is feeling some of that ripple. Commuters are buying row houses and multifamily houses in the Northwood and Castor Gardens sections of the city. From there, they can take elevated trains downtown, where they can change to Amtrak trains headed for Manhattan, or they can drive to work

Can't imagine *anyone* moving to Northwood (a lower-middle class older area in Philly) from NYC....
