That's why SF houses are significantly cheaper than their equivalents in suburbs like Palo Alto, Tri-Valley, Lamoraga, Marin, etc.

Or lemme put it this way - $1.5 million buys you a single family home with a backyard in outer sunset, but only buys you a townhouse with no backyard in the Tri-Valley, but the family in outer sunset will have to send their kid to a private while the Tri-Valley household kid will attend some of the best public schools in the nation.
