Hi Diane, looking for a wealth of misinformation? If so, RealtyTrac is a fantastic source. I have actually contacted Trulia about making it more obvious to users. RealtyTrac just posts public record notices. Vary rarely is the property even listed for sale.
If you are serious about a purchase you really only have two sources for accurate information: www.Realtor.com (which pulls listings directly from all Realtor MLS systems) or a Realtor's website (tied to a valid MLS.)
If you are not going to be living in the US when you buy this will be considered an investment purchase. What is your plan for returning to the US?
