said: "According to the Commercial Observer, which first reported 107 Columbia Heights' availability, the building could go for more than $1,000 per square foot, meaning more than $154 million at minimum."
That was reported only a few days ago! Now they only got $690/square foot, not a $1,000. Watchtower must have been very desperate!
