Nestled up against the rushing rapids of Kinderhook Creek in Valatie, New York, this historic property spent a century as a cotton mill before being converted to a hydroelectric power plant. Now that the turbines are offline, what was originally the caretaker’s home is on the market for $299,900. The building features an open-plan living space with one bathroom, a loft-style bedroom and a wood-burning stove.
