Was it the peanut butter cups that did it? Probably not. More likely the two hundred thousand dollar price reduction. Once that took place it was a mere four days before this house went under contract. The neighborhood includes the Beauregard Mansion and the German Marshall Fund Building so that helped too. Earlier today we posted another Dupont mansion, re-listed with a similarly sized pricechop. Maybe that's just what the doctor ordered (but that one is still a million more for about one thousand more square feet).
