"I'm calling a housing bottom tonight," an exuberant Jim Cramer told the viewers of his "Mad Money" TV show Tuesday. Cramer's call comes 14 days ahead of his original prediction, which called for a bottom in the housing market by June 30. However, after today's housing start numbers showed strength even in the nation's hardest hit areas, he amended his original call that was made back in August 2008. Cramer said the latest reports showing a rise in housing starts and permits were too large to ignore. He said it proves the glut of excess inventory is finally behind us and home builders feel they can safely get rid of the land they've been sitting on by building homes.
