Select realtors have been able to view the Massachusetts property for about a month, and the real estate has been owned by the family of Kerry's wife — Teresa Heinz Kerry — since 1982, the The Boston Globe reported.
One of Teresa Heinz Kerry's staff members told the publication to direct questions about the offering to Carolyn Duronio, a partner at the law firm Reed Smith. State Department Director of Press Operations Elizabeth Kennedy Trudeau declined to comment in an email.
The location served as a retreat for the former senator and Democratic presidential nominee. Kerry is currently traveling on the last leg of a trip that started in France and ends in the United Arab Emirates.
Duronio did not immediately respond to CNBC's request for comment.
