I continue to be absolutely perplexed by this sort of question. You get more information by calling a Realtor. It's free.
Besides, Weesh--and others who have the same question--you don't buy property that way, anyway. RealtyTrac and similar services don't sell a single home. Not a single condo. Not a single anything. All they sell is information that you can get for free.
What part of "free" do the people who willingly pay for those services not understand?
