Double check to see if the home is showing up as being actively for sale. That would be a problem since it's not on the market. However, if you key in just about any residential address -- for sale or not -- that property now shows up on websites like trulia, zillow, homefinder, Realtor.com, etc. because those sites pull data from various public property records databases. And since the property record is on those websites, the address will naturally show up in a Yahoo search or a Google search or a Bing search. It's a sign of the times.
