39 Edgewater Drive in Old Greenwich sat derelict and abandoned for years before it was finally put up for sale in 2013 at $780,00. A price war ensued, and the winner got it for $876,000. Those buyers completely restored and renovated it and this past March, listed it for $1.895 million and won again: they've sold it for $1.935.
In view of the previous discussion here about a lack of a garage hurting a house's chances, it's interesting to note that this house, too has no garage.
We wrote about this house back in March, when it went to contract, and there's a full discussion of both its merits and history in the comments.
