Real estate holdings while shrinking their adversary's home turf. Football is big business and so is real estate. It is estimated that nearly two-thirds of the fixed, tangible wealth in the United States is represented by real estate holdings. Employment in real estate and the construction industry typically accounts for five to seven percent of the total U.S. labor force. New real estate construction makes up about ten percent of the nation's annual gross national product. As an industry, real estate transactions score billions of dollars every year.
