Crowe, a former New Zealand captain who played 77 tests in a 13-year career, was diagnosed with the blood cancer lymphoma last October.
He is half-way through chemotherapy and was positive about the future.
"As anyone who has been through this will know, you have your good days and your bad days. We are staying positive and looking forward to a good outcome."
Crowe thought the four-level house would suit a family but was low maintenance so would also suit a corporate couple.
The bedrooms were on the upper and lower levels with the living area, and access to the pool and deck, in the middle.
"It even has a lift that goes from the carpark to the living area - it's great for bad knees," Crowe said.
The house has a valuation of $1.8 million, overlooks well-known Madills Farm and is within walking distance of the beach. Crowe's cricket caps and jerseys are proudly displayed in the large wine cellar.
Crowe and Downes share the home with Downes' teenage daughter Jasmine, by a previous marriage, and Crowe's daughter Emma, 9, also from a previous relationship.
