Even if you won PB, this home would be out of your budget!  I was looking up home values on Zillow and came across this blog.

I wonder what his utility bills run every month?   

Good thing I don't live in this house, however.  I'd never be able to find my keys! 

Forbes had an article on America's most expensive homes and the #1 was priced at $125 million, so I'm not sure if this house was overlooked since its estimated value is over $202 million.  Here is the Forbes article from June 2009.
