The United Nations' housing advisor has accused one of the world's largest corporate residential landlords, Blackstone Group, along with other private equity firms, of "wreaking havoc" in their tenants' communities and "helping to fuel a global housing crisis," according to The Guardian. Advisor Leilani Farha and co-author Surya Deva, chairperson of the U.N. Working Group on Business and Human Rights, singled out Blackstone Group's business practices in a piercing critique of the role of private equity in the housing market, the Guardian said.
