It’s an old story at this point, but if you’ve been following the Manhattan rental apartment market at all, you know the drill: vacancy is down, rents are up, new construction is scarce, and concessions are rare. Among the many explanations as to how we got here - and there are plenty - one of the most prominent is that Manhattan is a small island where space is limited, hence the lack of inventory. The reality is that this real estate platitude is a lazy way of analyzing our current market, one which obscures far more accurate explanations. For instance, the tight credit market for large new construction projects, government restrictions such as historic districts, and long-standing preconceived notions about certain Manhattan neighborhoods have a far greater influence on Manhattan’s rental apartment inventory than the size of the island.
