Dario and Rufrano of Kalmon Dolgin arrange $1.7 million sale of retail condo unit

According to Kalmon and Neil Dolgin, co-presidents of Kalmon Dolgin Affiliates, Inc. (KDA), the firm has arranged the sale of a 4,977 s/f retail condominium unit at 500 4th Ave., a new, 12-story residential development in the Park Slope section for $1.74 million. KDA brokers James Dario, Jr. and Fred Rufrano represented the buyer, David Dosik, M.D., and the seller, Park Slope Group. Dr. Dosik, who specializes in internal medicine, will use this space for Hematology & Oncology. The property at 500 4th Ave. is a 156-unit residential property with three retail units that are new to the market. Last year, Messrs. Dario and Rufrano negotiated the $825,000 sale of one of the units to Sunflower Day Care, a day care provider. The building offers doorman service and on-site parking. Before its conversion for residential use, the property served as a warehouse for a beer distributor. 500 4th Ave. is located on 4th Ave. at 13th St. It is close to the R subway line, and is convenient to the Gowanus and Prospect Expressways.
