The price tag for being host of the Olympics just got heavier for the New York group trying to win the U.S. bid for 2012.

The New York Post reported that it obtained financial documents placing the potential facilities cost at $6.5 billion, far exceeding the $2.4 billion initially cited by NYC 2012.

Less than three weeks remain until the U.S. Olympic Committee selects San Francisco or New York as its candidate city for the 2012 race.

New York's construction costs almost lost the city a spot among the two finalists in August when the U.S. bid city list was trimmed from five. Sources said NYC 2012 officials allayed concerns by stipulating that the proposed construction would take place even without an Olympics in the city.
