A single-story brick industrial building at 83 Seigel St. was sold in an all-cash transaction valued at $470,000. The building occupies the entire 2,500 s/f lot. The site has 3,000 s/f of air rights for potential residential development. Massey Knakal director of sales Mark Lively exclusively handled this transaction. "The sale of this site is a good example of the growing interest in East Williamsburg," said Lively who exclusively handled this transaction. "There were several users interested in this property but due to the residential nature of the block development use made the most sense to the purchaser."
