Prices for homes in Northern California are notoriously steep, with tech money contributing to a somewhat inflated real estate market. According to a recent , luxury home sales in the area continue to grow, with 2,604 homes selling for more than $2 million last year. This was a 28% jump from 2012 and the highest number ever recorded. Heres A list of some of the most expensive homes for sale in nine Silicon Valley cities: Palo Alto, Portola Valley, woodside, Sunnyvale, Cupertino, Campbell, Monte Sereno, Los Altos, San Jose, and Mountain View. Palo Alto — home to tech giants Tim Cook, Marissa Mayer, and Mark Zuckerberg — completely dominated the list with 7 of the 15 priciest homes on the market. You may be surprised to see how much these homes really cost.
