for everyone saying that that is a lot for what you are getting: you all are super ignorant about real estate. Location, location, location!!!
My fam moved to my neighborhood in the 70's and paid 150k for the house. nice house, but very middle class. after silicon valley blew up and all the influential people decided to settle down in the area, my house is worth millions. if you saw it, you would think 250k-300k max.
A brand new, state of the art house, with every amenity and luxury imaginable, in one of the most desirable areas in the world is going to cost a damn pretty penny.
