Real Estate Barometer San Francisco | also called “PRESTIGE HOME INDEX”. Published annually by First Republic Bank. It is showing the value of an average real estate in the San Francisco area. The Prestige Home Index got introduced in 1985. By then a house had been sold for roughly $500,000 on average. In 2013 that same house had a market value of $3,000,000 = six times as much compared to 30 years ago. Unfortunately I don’t have similar statistics available for communities such as Palo Alto or Mountain View. But numbers would match those of the San Francisco area.
