Houston is often cited as being one of the most affordable cities in the nation. But is it really? Irene Vazquez, a student and writer for Rice Design Alliance's OffCite, wrote an article this summer looking at income segregation and home prices in Houston. The takeaway: The city is divided into two parts – the arrow, which covers the historically wealthy parts of town, and the horseshoe, the rest of the city. Lumping the two together can lead to a false impression about housing and affordability. Vazquez talks with Nancy and Allyn about what she learned from her research. She also sheds light on what people from her generation think about home ownership.
