Larry brings up good points you would have to register on Reatly Trac to access the information, and there are no active listings in the Multiple Listing Service with an address on Kennesaw for a listing price of $85K.
Realty Trac publishes pre-foreclosure data, and is a subscription based company. The data they publish is usually accurate, however, in the case of pre-foreclosure documents, simply because a document has been filed does not mean the property will go through the entire foreclosure process. Many times there are properties listed for seemingly very low prices because the owners missed a payment on their 2nd mortgage, not because the house will be sold for that price.
If a home price seems too good to be true, as in this case, it usually is. If you work with a Realtor, she/he can help you find TRUE foreclosure, and preforeclosure propeties.
