Parts of Palo Alto were very blue collar post WWII. I knew one nonagenarian who bought his house new in 1949 for $10k, and it sold, unimproved, for $2.2m on his death over a year ago. Also a centenarian still living in her original 1950 $10k house that Zillow now estimates at $2.3m. So, there's 220x gains. Clearly, all the value is in the land. Property tax in 2013 was about $1k in both cases; both have new neighbors in newly-built $4m houses on same-size lots paying $40k tax.
