Assessor: Mansion that sold for $100 million worth half that

Silicon Valley mansion was never on the market, seller financed part of deal

A 25,500-square-foot Silicon Valley mansion that sold last year for $100 million is worth only half that much, according to the Santa Clara County assessor’s office.

The home’s new owner, Russian venture capitalist Yuri Milner, can take solace in the fact that his $600,000 annual property tax bill will also be about half of what it would have been, had the home been assessed at its sale price.
