Beck never did have very good perception.
Btw, he only lowered his asking price by a bunch. Whoever was advising him on his financial affairs was probably his political consultant as well.
What can I say? It's the existing market condition here.
Beck isn't the only one who's taking less than they want for their mega mansions.
Even the smaller McMansions are going for less than what you'd expect.
Give it a few years and the market will probably turn the other way.
