The Jonathan Rose Cos., a national developer of mixed-income and affordable housing and other mixed-use redevelopment projects, earlier this year announced a $500 million purchase that has added one Stamford property to its presence in Fairfield County.

Headquartered in Manhattan, the real estate company acquired Forest City Realty Trust’s affordable housing business, which included 48 affordable housing communities in seven states. In Stamford, the buyer paid $24 million for Shippan Place, a 148-unit Section 8 senior housing complex at 521 Shippan Ave.
