Following the crisis, nonbank specialty servicers rapidly expanded their portfolios of distressed loans. This has contributed to a significant market change: in 2011, the 10 largest mortgage servicers were all banks; by 2013, only five of the top 10 were banks, and the other five were nonbank servicers. The rapid growth and lack of a federal regulator have contributed to significant, heated regulatory scrutiny. This commentary discusses major concerns raised about the largest nonbank servicers, focusing on the three fastest-growing large nonbank servicers. We explore the regulatory and market framework driving their striking growth, then address the major charges against them, in an effort to elevate the debate and inform sound policy.
