Thank you for your question Mr. Chambers:
As the others have pointed out, that information on those websites for REALTORS listings is taken from The Multiple Listing Service.
Are the listiongs that you are talking about REALTOR's listings or listings by for sale by owners?
If the properties that you are seeing not updated are REALTORs listings, then there may be a problem with the update from the Multiple Listing Service to the websites that you are looking at.
REALTORS update their listings on the Multiple Listing service. However there are a number of websites who take their information from the Multiple Listing Service. Those websites need to use the information they receive from The Multiple Listing Service to update their websites.
I know that some people say that we as REALTORS should play private detective and track down the 6 or 8 or more major web sites that pull their data from The Multiple Listing Service and go into each one of those sites manually, and update each one of those sites ourselves.
However many of those web sites will not even let us individually go into those sites to correct the information on our own listings. If that website does not update from The Information that they receive from The Multiple Listing Service, we have no way to even correct that information ouselves.
This is actually probably a good thing because the hackers out there would just use that as an opportunity to hack into the website and change the information in whatever manner they wanted to do so.
Once these websites take our listing information from the Multiple Listing Service, that information is out of our control. The website that took our information needs to keep their website updated with the new information that they receive from The Multiple Listing Service.
The best solution is that if these websites will not keep the Multiple Listing information updated , then they should lose the right to pull information from The Multiple Listing Service.
If the out of date listings are from For Sale by Owners, one of the best solution is for those websites to have the listing expire every 7 days, like they do on craigslist so that you do not have out of date information on the web site.
