The recently announced sale of servicing assets on more than $300 billion in unpaid principal balance may represent one of the largest chunks to move from the banking system to nondepository servicers, but executives in the specialty servicing sector emphasized that they still see plenty more coming down the pipeline.

"We're optimistic that there'll be more to do," Nationstar Mortgage Holdings Inc. CEO Jay Bray said. The CEO of competitor Walter Investment Management Corp. agreed, putting his company's own exclusive pipeline at about $60 billion.
