Here's my question to you Stephen. How well do you know the zip codes in the area? Not just the zip codes but the school district in those zip codes. In my previous experience with real estate agents  I have felt like they don't know their surrounding areas, not to mention the areas that they work in. Speaking to to these agents they say that they purchase Zip code maps on the internet. Do you do this. Do you find these maps helpful? I have heard of agents using http://www.zipcodeguy.com. Have you heard of this company? Let me know what you think
