Just weeks after a Mosman waterfront trophy home hit the market for between $17.5 million and $18.5 million it has sold.

The exclusive harbourside suburb has scored a run of top sales results this year thanks to a tight listings market, of which one set a suburb high of about $23 million in February for the home of former Foxtel chief executive Richard Freudenstein and his wife Jane.

John Blewitt, one of the pioneers of the financial-planning industry, and his wife Rana are the latest local vendors to cash in their high-end real estate.
