The aerial photos or satellite images are taken at a specific time in the past. They do not update these images. So what you are looking at in the image or topography of the area before the developer came in and flaten the land and put up the houses. At some point in the future if they update these aerial photos with the most recent pictures and these homes will show up. Until than enjoy the natural topography. It gives you appreciation for the nature!

The satellite maps are really cool, but they still don't replace the need to drive through neighborhoods once you narrow your search. I just got the deal of a lifetime in Mountain House. In fact, my neighbor moved here from San Bruno...your neck of the woods. Good luck!
