Greenwich, NSW

Saying goodbye to your home of 50 years is always going to be tough. But when it has 180-degree views of Sydney harbour and the water is at the bottom of the garden, it's downright gut-wrenching.

But views or no views, this house has a sinister secret behind that cupboard door that sends buyers running.
