I live in a place (Bryan/College Station, TX) where the main industry is a university (Texas A&M). College students make up a huge proportion of the population.
We have a recurring problem in which developers will up-zone whole neighborhoods from single-family homes to larger, student-focused group homes. Property values will drop in those neighborhoods, and they will become "student ghettoes" or "student slums."
From a Strong Towns perspective, I feel I should approve of incremental, lot-by-lot up-zoning, since it's a better way to house people than creating sprawling apartment complexes or block-sized mid-rises. But in this case, it seems to have negative effects. The large group houses are ugly and shoddily built (especially compared to the houses they've replaced), and they encourage poor caretaking from the students, whom nobody wants to live next to as a consequence. But because few families' incomes can match the combined resources of a bunch of students, there seems to be no market recourse.
What can be done to address this that doesn't involve rigid zoning requirements or NIMBYish neighborhood associations?
