I think you misunderstand how Trulia works. The link you have is showing a previous sold record. Actually our local MLS shows this house expiring Dec 08 at $448k. Maybe you are selling as a FSBO but it is not an active listing on the MLS. Asking price of $438k in Willingboro OUCH!! Home values has faced a serious decline in Willingboro. Buyers can purchase 4bedroom 2.5 bath new construction or home less than 10 years old in Florence, Hainesport, Bordentown and Burlington for around $400k. I'd recommend a serious price reduction!!
The records show that this house is no longer actively listed. It was listed for $448,000 in 2008 but expired off the market after 184 days of being unsold. If it is for sale by the owner, that would have to be updated by the owner.
