Recently, Luxury Rentals Manhattan posed a question that anyone searching for a NYC rental apartment has surely asked him or herself: "Are Manhattan rental apartments now a rich person thing?" It’s no secret that New York City is the nation’s most expensive place to rent, and although -- given how much more expensive it is to buy a Manhattan apartment -- renting in Manhattan still seems like the way to go, it's all relative: MNS’ figures show that in May 2011, rental prices increased by 6% from last year’s average. That's overall, though, and as anyone browsing Manhattan rental listings has surely noticed by now, rental prices, while high throughout Manhattan, are highly variable, even between bordering neighborhoods. Averaging studio, one-bedroom, and two-bedroom costs for each part of Manhattan shows that Tribeca is New York’s most expensive place to rent, while Harlem is the cheapest. That’s not particularly surprising, but some of their findings are. Contrary to popular belief, or common sense for that matter, renting in the Upper East Side is actually less expensive than renting in Greenwich Village, the Upper West Side, or Chelsea. So what does any of this have to do with rezoning North Tribeca and lowering housing costs?
