State regulators, the U.S. Consumer Financial Protection Bureau (CFPB), and some mortgage industry players have expressed concerns about the rapid growth of servicing companies such as Nationstar Mortgage Holdings, saying these companies could trigger unnecessary foreclosures by potentially taking on more mortgage loans than they can process. Housing finance giants Fannie Mae and Freddie Mac raised objections earlier this year when Nationstar tried to buy the rights to collect payments on $122 billion of mortgage loans, not long after winning the rights to collect payments on a separate $215 billion mortgage portfolio. Home loan servicing transfers are being scrutinized by state regulators and the CFPB, with the latter issuing a bulletin in February cautioning home lenders about their consumer protection obligations during the transfer. In one case involving a transfer to Ocwen Financial Corp., a homeowner in San Antonio says she did not receive the booklet of coupons to send with her monthly checks. Ocwen would not accept her checks, initiated foreclosure for non-payment, and provided conflicting information when she later tried to secure a loan modification, says the homeowner. It remains to be seen whether banks or independent payment collectors generate more complaints per borrower.
