I came across this article in the Times from 1987 completely accidentally, while I was researching something else. It details the rise of gentrification in the Hill, starting around 1981, and talks of the process of converting the Clinton Hill Apartments into Co-ops. It's an interesting read to see how much has changed and how much had stayed the same all at the same time. Diverse middle class? Check. Neighborly vibe? Yup. A one-bedroom rental for $550 a month? HA! I can't believe my luck in finding this 20-year-old article!
