Mr. Cooper launching mortgage-linked credit card 

Mr. Cooper, the nonbank that officially left the name Nationstar behind on Monday, is already the most unique name in the mortgage business. As part of the company’s rebranding efforts, Mr. Cooper rolled out a number of features designed to improve its customers’ experience with the nonbank. But one of the features the company is rolling out is something almost unheard of in the mortgage business – a mortgage-linked credit card.
