I found myself recently in the town of Larkspur, in Marin County, just north of the Golden Gate. Looking for a shady place to park, I pulled into a side street and came to a stop in front of the house pictured here. In front of the shack-like building was a "for sale" sign. One bedroom, of less than 700 square feet, un-landscaped, old and not very well put together to begin with, this is something you might pick up for about $30,000 in many parts of the United States--say, in central Alabama. Price in Larkspur, California? $800,000. It truly is all about location.
