While this is not strictly a foray into real estate (think hotels, executive suites, etc. instead of Google's failed real estate search), it is certainly a step in that direction... And, in New York City, the line between rentals and short-term rentals (though legally clear) has always been rather vague (i.e. most of AirBnB's vast database is "technically" illegal in NYC). So, this new Google search tool might be something interesting to watch.
