The Washington Post recently updated their article with the following: 

"An earlier version of this story stated Cornwell Farm was at risk of demolition. The developer now says he had no plans to raze the house." 

This is great to hear that Cornwell Farm is no longer in any imminent threat of danger. If you know of any interested parties interested in purchasing and conserving the property, please share that the Georgetown Pike Rural Preservation Trust is seeking a buyer.
