Millionaire philanthropist John Kinghorn is selling his Mosman harbourfront mansion with $16 million hopes.
The founder of RAMS Home Loan and wife Jill Kinghorn have owned their waterfront home in Mosman since 1982.
It is listed through Belle Property.
The five-bedroom Carrington Avenue home was bought in 1982 for $1.3 million having been built in 1978 with four levels.
There were renovations in 2013.
It comes with swimming pool, boat house, jetty and a pontoon.
It was briefly listed in 2011 with $9 million hopes when they planned to spend more time at their Bilgola beachfront house which was sold in 2013 for $5.35 million.
