How to Buy a Silicon Valley Mansion for $150

Do you feel lucky? Would you like to own a Silicon Valley 6,700 square foot seven bedroom mansion at a cost of only $150?

If your answer is 'Yes' to both questions, you may want to enter the Third Annual Silicon Valley Dream House Raffle. If you win and you would rather not own the Menlo Park, California home, you can accept the alternative price of $4 million.

The money that is raised from the auction benefits the Yerba Buena Center for the Arts. There are also some early-bird prizes.
