Yes, getting expensive, especially high up in the Hayward Hills with view to the bay.
Last weekend, I visited one of the builders inside the Stonebrae Country Club (top of Hayward Hills.)
I remember about one and a half years ago, when they finished/released the first house on their street, it was about $1.1 million...
Last weekend they told me the last house on that street was just finished/released, and the price (same floor plan) was $2 millions. Almost double the price.
And there is a waiting list of buyers on that house.
