Can you site what you are referencing with these figures? Seems like maybe things are in the wrong fields from a feed that this site takes. 455,000 sounds like it would be a purchase price, not an amount of square footage.
Was this a short sale? A bank foreclosure? Also not sure what site you are looking at - there are some sites that record the amount of the loan the bank has forgiven, and not the list or sale price. For only $6/ sq ft anywhere sounds inaccurate to me.
