HUDSON COUNTY, NJ — In New Jersey’s geographically smallest – yet most-densely populated – county of Hudson, Gebroe-Hammer Associates has arranged the sale of 106 apartment-rental units sold for a combined $16.29 million. The firm’s Executive Vice President Niko Nicolaou exclusively represented the two separate sellers and procured the buyers of 246 Summit Ave. and 4501 Cottage St., in Jersey City and Union City, respectively. Commonly referred to as New York City’s sixth borough, Hudson County has been undergoing a two-decade population boom where the renter base is expected to swell even more in the foreseeable future.
