I live in Las Vegas which was one, if not the worst place to own real estate during this recession. On one of my own properties they state it was sold in December of 2007 for $283,000. I purchased the home in 2000 for that amount but in 2007 placed it in trust and this was not a sale. The home at that time was probably worth around 750,000. I have asked them 3 times to correct the data as it does affect values. As a retired appraiser, I have also found that they are under estimating by about 20 to 30%. Unfortunately buyers do rely on this totally inaccurate site to help them make decisions when they are making offers.
