This house next door is sale for $12,000,000.

Considering that one of two townhomes left remaining directly on Rittenhouse Square Park is listed for under $6MM, it is still way overpriced for a single family home of this size. The Cerrones must be out of their mind to think they will sell it for anything close to that. On the other hand, it is perfect for Astoban or another developer to purchase the lot to build a tower.
If I had to choose between an overbuild of the Nelson Building or a tower build on this plot of land, I'd choose this plot in a heartbeat even if it meant total demolition of this house.
