The latest monthly home sales and price report from the California Association of Realtors says that the median single-family home price in the Bay Area was $852,230, up 11.5 percent year over year while home sales dropped 14.2 percent from August and 4.2 percent year over year.

Once again, tight inventory is responsible for the rise in prices and the decline in sales.

Active listings continued to fall by more than 10 percent every month and declined by 11.2 percent in September.
