Baltimore’s flashiest developer wanted to expand nationally. Now he’s rethinking everything.

Brandon Chasen is one of most dominant players in Baltimore real estate. His namesake company has developed boutique apartment buildings in Fells Point and is overhauling historic properties like the old Meyer Seed Co. warehouse and the One Calvert Plaza skyscraper downtown. The 38-year-old Potomac native, who leads the firm with his best friend from prep school, has made waves for his embrace of a luxury lifestyle: penthouse suites, designer clothes and yachts. His ambitions grew to include what he said would be a $100 million investment in projects across the country.
