A property of this caliber would sell [even in this market] for NO LESS than $800/SF-
Since it is being offered for lease- who knows;... the owner may be very open to listen to what you have in mind.
That is a trophy property!
Sorry to tell you that this is the rental price for a seasonal rental.
It is deceiving, they do not have a seperate area for rentals on Trulia.
Please contact me if you have any other questions.
