If you go to the dataquick.com website they have information on ordering custom reports. Alternately every month dataquick posts the sales activity by zip code for the entire county. HOWEVER, the San Diego Union actually prints it all out every single month. If you go to a local library you can most likely get the tables for each month for however many years back you want to go. The only problem is that it will be a hardcopy not a soft copy.
