Kash points to this story about political considerations as a factor in determining where to buy a house. It’s some more empirical evidence for the Great Divide thesis that Bill Bishop has been writing about.
Of course, yard signs during campaign season aren’t really necessary for this kind of self-sorting. We had some neighbors a few years back (a married couple about our age) who came to Houston to follow a job. The job was in the Woodlands, and they were set up through the employer with a real estate agent out there. They looked there, but having done some research beforehand they knew that the Woodlands was not a good match for them. So they asked the agent about Montrose and the Heights. The agent responded that in her opinion, those parts of town were crime- and drug-ridden dens of iniquity, and she refused to show them anything south of FM1960. They found their own agent, and everything worked out in the end.
