Home prices in California have dropped almost 42% from a year ago, November, as a glut of foreclosed homes drove first-home buyers to buy on the bottom end. Statewide, a single-family home cost a median price of $285,680. In Los Angeles County, the San Gabriel Valley housing market is in bad shape. According to the California Association of Realtors, prices around the San Gabriel Valley ranged from lows of $256,000 in La Puente to highs of $692,500 in Arcadia, which saw a slight drop of only 4.8%, compared to last year.
