Ally Financial Inc.'s banking subsidiary said on Friday that it was looking to sell most of its remaining mortgage business, the company's latest step toward exiting the home loan business to focus on its U.S. auto lending and banking operations, Reuters reported. Ally Bank said that it was exploring strategic alternatives for its agency mortgage servicing rights portfolio and its business lending operations. The portfolio had $122 billion of mortgage loans in the third quarter. The company, which is majority owned by the U.S. government after a series of bailouts during the financial crisis, is also selling international operations in a bid to pay back taxpayers.
