One of the nation’s largest mortgage lenders, ABN AMRO has taken aim at the alternative mortgage market with a slate of new products that borrowers can access through its online Mortgage.com portal. The online site is a major part of ABN AMRO’s retail origination strategy. Through the end of September, more than $2.3 billion in new loans were originated via Mortgage.com, a figure equal to 25 percent of ABN AMRO’s total direct-to-consumer business.
