A changed mortgage lending industry will emerge from the crucible of the current credit crisis. New ways of thinking will be required about everything from products to risk management and regulatory compliance. Like its Web 2.0 cousin, Mortgage 2.0 aims to facilitate greater creativity, information-sharing and -- most notably -- collaboration among users. It is made possible because it is being built on a foundation of technologies designed with just such goals in mind. Mortgage lending technology has come a long way over the last few years. The static, cumbersome loan origination systems that lenders historically deployed are being replaced with more dynamic and agile solutions such as service-oriented architecture, and with a new delivery model called software as a service. Innovation will not slow down in the face of the current crisis. If anything, history tells people that difficult situations spur more creativity and new ideas.
