It's no Ian Schrager penthouse, but #6D at 40 Bond is making its own bid for the record books. The 1BR-plus-library/office hit the market at the start of March asking $18,000/month, and a tipster tells us it has indeed rented for that price. Never change, Bond Street. Back in 2009, the apartment sold for $2,036,500 after asking $2.5 million?so maybe the rental market is a better choice for this pad, anyway. We're not sure who the deep-pocketed renter is; intel to the tipline or to comments.
