Your question is a little vague. Are you asking about neighborhoods or your neighbors...

My collegues have provided some great answers regarding the satellite feeds. Keep in mind that depending on the age of the neighborhood, in areas that are experiencing explosive growth like the Phoenix area, the satellite feeds are a few months behind. I would like to piggy back on Linda Jandura's answer and suggest that you enlist the service of a Realtor who is familiar with the neighborhood you are interested in seeing. They may be willing to preview the neighborhood. Many Realtors are proficient in taking digital camera shots and can send them to you via e-mail. While pictures are helpful, there is no substitute for touring the neighborhood personally, taking in all the sights, scents and sounds.

This is one of the top reasons why we say "you can't buy a house on the Internet"! You can't really tell what the neighborhood looks like, if a neighbor down the street has junk cars, etc.
Also, what you can't tell from the Internet is floor plan of the house and how the house flows. And believe it or not, there is no "scratch and sniff" to see how a house smells! We've shown what seem to be a beautiful home but once you walk in it smells like cigarette smoke or cats and the client doesn't want to go any further.
You can get a general idea of the neighborhood and other houses from satellite websites, etc, but you have to be there in person to see the neighbors house.
Best of luck

Google the address and you should be able to see the satelite pictures of your neighbors homes. This, unless the area is too remote and the pictures were not taken too closely.
