CNN Money.com has a feature right now of the dumbest moments in business for 2009 and included is one real estate transaction.

The 80,000-seat Silverdome was the National Football League’s biggest venue when it was built in 1975 for $55.7 million. … In an auction back in November, an unidentified Canadian real estate company had the winning bid — of $583,000, which is about 1% of its original cost.

Ouch.  Yet it reminds me that $55 million times zero (zero attendance, zero interest, zero return) is still zero. That $583,000 bird in hand is better than two birds in the bush.  Still… ouch.
