I did some research on this property and since RealtyTrac does not provide an exact address, when we see these sorts of posts in Trulia we have to do some detective work. Here's what I can tell you.
The most recently available house on the street (and the only one currently active in the MLS) is listed for slightly less than what RealtyTrac lists it as (MLS - $118,000 and RealtyTrac - $137,04). I checked a foreclosure site I use as well and I can find no record of a home on Poinciana Street, but I think it must be the home you're referring to as it looks like they were trying to sell it for awhile (since July 2008) and went through several aggressive price drops and marked the listing with terms like "motivated seller."
I can send you over the MLS data for the property that I think must be the correct one if you'd like, just send me an email or give me a call. After you've reviewed that, I'd be more than happy to discuss it further with you.
Hope that helps.
