Balancing affordable housing and density

When Vanderbilt polled Nashvillians in March about top priorities for city investment, there was near unanimity around one issue. Nearly 90% wanted investment in more affordable housing. But when the questioning hit closer to home, the support waned. According to this same poll, 56% of residents support allowing multifamily housing "everywhere in my city to revitalize neighborhoods and local economies."If Nashville is going to have more affordable housing, residents also have to live closer together. It's not just apartment buildings and not just in some parts of town. It’s townhomes. It’s a garage unit in the backyard. It’s density. And when that density is proposed next door, you get a lot of folks who may agree in principle but find themselves saying “not in my back yard.” What does it take to get more YIMBYs (yes in my back yard)?
