How big real estate firms, often from abroad, are buying up apartment buildings in the Bronx

WNYC's Cindy Rodriguez has a piece today on how big real estate firms, often from abroad, are buying up apartment buildings in the Bronx and Northern Manhattan. Fueled by the weak dollar, foreign firms are purchasing properties "this cheap stock of housing that’s far from luxurious." But at the current rents these buildings are barely profitable (if at all), so they still can't be considered bargains even for someone buying with euros or pounds. The deals only work for the investor when they can raise the rents.
