From the web blog http://www.shimonsandler.com/?p=126
we learn care of Avi Wilensky who contacted Shimon Sandler that Google has released: Google Real Estate. We are unsure whether this is it's official name. If you do a search for 'real estate', 'homes for sale', or 'apartments for rent' a new option appears as pictured. A better view is available on Shimon's web blog (link above). Begs the question as one commentator puts it:
Google Real Estate is in direct conflict to and competitive to real estate advertisers in AdWords of which we are one. If you are going to compete with advertisers we will have to discontinue paying you to steal our customers…
That sure is a serious point! I wonder if Rightmove know about this? They must, surely?
