Tree-lined streets and multi-million dollar homes characterize beautiful Los Altos. This high-end haven north of San Jose works hard to keep the area beautiful and exclusive, with everything from heavily promoted community involvement programs to tree protection regulations. Not surprisingly, the median sale price in the Los Altos real estate market is $1,507,500, narrowing the buyers market considerably. But residents who can afford homes in Los Altos enjoy 12 city parks and wilderness areas, bucolic neighborhood streets, special town events, a thriving, upscale downtown area and a selection of top Bay Area restaurants.
