Google Real Estate Search?

From the Google Friends Newsletter (April 2007):

Now when you type in queries like
[New York real estate] or [homes for rent in San Francisco], you'll
see the location you're interested in and type of listing at the top
of your search results. Clicking the "Go" button will display details
of individual homes that Google has indexed. If a certain listing
interests you, click on the provided link or image, to go straight to
the listing source.
