Mike lived with his stepfather in the Queenstown house for about a year before moving to Invercargill to live wih his mother, Fiona [Fengjuan] Lu, in Invercargill.
The three-bedroom 271sq m house has a rateable value of $700,000 but is likely to sell for double that. It is owned by the Ozprey Trust, of which Mr Beckenridge is a trustee.
A dispute over who gets the sale proceeds is unlikely to be settled until a coroner rules on the case.
