I always laugh at suburbanites that look at a 60 floor building and claim oversupply. Yet a new subdivision or two may occur on the fringes of a suburban town and no one things anything of it.
These structures are about 300 units each. Jersey City is easily absorbing 300+ apartment units monthly due to a rising population. This one 60 story tower represents a one month supply. An average subdivision may be a couple hundred homes. Yet no issues when those are being built. It's only an oversupply if it's contained in a tall, single building.
