The sellers (and agents) are still trying to keep the address under wraps but a two million dollar price cut is still enough to get everyone's attention. For a few short months this was the most expensive house in the area (until an $18M one in DC jumped ahead of it). But now its asking price is an even sixteen million dollars. The six bed, ten bath (only two of which are half baths) overlooks the Potomac River and comes with a pool and guest house. There are plenty of pictures of those parts of the house, plus the main living areas, but there are very few of the upstairs rooms.
