Unfortunately, at these public sites, you can't tell the difference. If you are searching for farms, land, multi-unit residential, commercial property, mobile homes and business opportunities, this is the only site that is at all accurate. One drawback is that the search criteria are limited. While very similar to the California Living Network , it seems to be less accurate. You may prefer the display options, however.
Some listings have links to virtual tours.
If you have a slow connection, you can speed up your results by selecting the no photo option. For more than a year, a test search for Petaluma has produced the wrong elementary, junior high and high school. Last time I checked this site, it found only 16 of 96 possible listings in West Petaluma. This time, it said there were 114 when there were only 99. It can try to set as many as 50 cookies before it processes your search.
