NEW YORK CITY-Dermot Property Associates has sold a 14-building, 861-apartment portfolio here for a total of $190.5 million, says Cushman & Wakefield, which arranged the sale. A C&W spokesman declined to identify the buyer or buyers; published reports had identified the Great Neck, NY-based Parkoff Organization as the purchaser of 10 of the properties, which range in vintage from circa-1900 to the 1930s, while the other four reportedly went to Douglaston Realty.
