The internet is a wonderful thing that allows access to lots of information. Once that information is "out there" there appears to be no way to delete it. The information on your home was published to the internet to allow people to find the home when it was for sale. That information will continue to be there for years to come. I still get questions on homes that I had listed and sold several years ago from people that search on the internet.
I always advise my clients to have all the locks re-keyed and to change access codes for any garage they may have. This will make your home as safe as it can be from unwanted intruders.
Hope this helps.
