18 Rocky Point Rd has cut its price by $900,000, from $8.750 million to $7.850. That’s still not chump change, of course, but Old Greenwich waterfront has been flying off the shelf, and this, from its photos, looks like a gorgeous home. What gives? Was it blasted by Irene, or Sandy (I note a $4.5 million mortgage went on in 2011)? Locals in the know, please contribute here.
