Garland, Mesquite, Carrollton, GP, East Plano. Any of the post WWII areas that were built on straight up suburban principals of use exclusivity. There is no land value pressure and the initial housing was cheaper, so you're left with cheaper apts and houses. No different than what happened in those areas of Dallas specifically. Its textbook urbanism. The inner-city land values eventually have too much pricing pressure to hold onto cheaper priced housing and the post WWII suburbs usually end up as the poorest parts of a given metro area. Newer suburbs try to build more nodally to avoid that, so you see your Southlake Town Centers, Las Colinases and Legacies along with higher priced homes. Its an attempt at city-like sustainability. So if Dallas continues to grow, this cat is out of the bag now. Some areas are going to see massive demographic shifts or some areas wiped out and rebuilt. That's what Uptown is. My neighborhood is already headed there.
