Living in Morningside Gardens

I was perusing a years old discussion of Morningside Gardens, and thought "Wow! So much has changed." While the hallways are still dingy, most apartments have been renovated, and those that aren't reflect it in prices. The "campus" was recently repaved, and while some changes were controversial, it still offers a tranquil green oasis. Maintenance costs are still reasonable, and partially deductible. With two new upscale condos nearby, and Columbia University completely reopened, the neighborhood feels like it's coming alive. I don't understand why more potential homeowners don't see it as the alternative to Brooklyn which is now actually more expensive. It certainly fits a space of affordability for people who can't afford a million dollar one-bedroom. What am I missing?
