This map is draggable, you can use your mouse or the directional arrows to pan left, right, up and down to see areas that are hidden offscreen. You can also use the + and - buttons to zoom in and zoom out.
To see details of listed properties, click on the orange marker. This will show summary information and allow you to access the detailed listing.
Want to see what your selected property looks like in real life? Check out the satellite view, which gives you access to satellite and aerial images of the listings that you can zoom in, zoom out, or pan in any direction. (You won't experience any long reload times when you drag images in the satellite view, either.) To access this view, click "Satellite" at the top right corner of the Google Maps page. You can also choose the hybrid view, which superimposes map data - including streets, street names, and landmarks - over satellite images.
