Prominent Sydney-based real estate fund manager iProsperity Group has become a casualty of COVID-19 with administrators appointed after income dried up from its hotel investments.

Barry Wight, Jeremy Nipps and Alan Walker of restructuring advisory firm Cor Cordis were appointed voluntary administrators of 13 iProsperity entities on Thursday. The entities included iProsperity Underwriting, an entity already forced into receivership by ASX-listed Agricultural Land Trust in May over a loan dispute.
