Over the past 20 years, the mortgage and securitization markets grew in size and importance -- in part by relying on certain kinds of data and analytics to assess risk across the origination, ratings, securitization and servicing spectrum. But the cascading events of the past two years clearly demonstrate the significant limitations of this information and how it has been used. There are several types of underutilized data resources available to the mortgage industry. One of the major limitations of currently used loan-level data is that it does not capture changes in borrower and collateral characteristics that might happen post-origination and/or post-securitization. As for changes in property value, and beyond the use of generic home-price indexes, automated valuation tools are available, and can provide collateral valuation tailored to the property's characteristics, as well as its geographical location. As new forms of collaboration blossom, new terms find their rightful way into the business dictionary.
