This add-on for google maps is a little hard to find. When you open google maps, there are two search boxes. Click the second box and a drop down list appears. Select real estate. Then type in whatever address you are interested in in the first box. A map with red dots representing properties for sale near that address will pop up. Then you can use street view to zoom in and see how the neighborhood looks. Chicago magazine wrote about it recently, so it must be cool.
