Real estate finance law is market-driven and therefore constantly changing. This treatise provides current, expert coverage on the law of mortgages; the necessity and nature of obligation; mortgage substitutes; foreclosure; statutory impacts; subrogation, contribution, and marshaling; government intervention; and financing real estate construction. Additional consideration is given to the potential liability for cleaning up hazardous waste and the impact of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).
