Dina and Brian,
As you can observe, there is great confusion in the real estate professional community regarding the source of data appearing on Zillow and Trulia.
Anthony has it correct.
The data you mention DOES NOT COME FROM ANY MULTIPLE LISTING SERVICE!
As Anthony suggested the outdated source for your homes feature is ListHUB. Listhub and Trulia and ZIllow and every other website parading as a real estate website reserves the right to replace, change, suppress, alter, modify, delete and misrepresent the data in what ever manner suits their business objectives. These sites are suitable for entertainment purposes only.
If you have suffer material loss, mental anguish or other substantiated damage, contact your attorney. Maybe YOU can make them accountable.
The most likely source of your faulty data is your local tax and appraisal authorities. Be aware, if the SF is increased, so will the value...so will your taxes.
Serious buyers rely on the multiple listing service for actionable data. Don't loose sleep on what appears on entertainment websites.
However, you SHOULD go to Google Maps and blur your homes street view.
