In his Essay, Professor Korngold gives a broad overview of the subprime mortgage crisis and suggests emerging issues and questions that must be addressed in the years to come. In particular, he addresses two broad issues: the regulation of mortgage lending and markets as we go forward and the law of mortgages in the aftermath of the financial crisis. He concludes by offering some thoughts for legislators, judges, regulators, and market players on how some aspects of the crisis might be considered and resolved.
