The U.S. Embassy put 400 Acacia Ave. up for sale last week, a historic property it's owned for 58 years. Realtor Marilyn Wilson says the sale is part of a land exchange deal she negotiated between a client and the U.S. Embassy. U.S. Deputy Chief of Mission John Dickson had been living there, but has since moved within the neighbourhood, says Ms. Wilson. Asking price is $2,850,000. Visit www.rockcliffepark.com for details.
