United Petroleum founders Eddie Hirsch and Avi Silver have stripped down their commercial property portfolio after selling the premises of Melbourne gentleman's club Goldfingers on seedy King Street for about $50 million.

Well-placed sources confirmed the notorious strip club premises and three neighbouring buildings near the corner of King and Lonsdale Streets – held in various entities co-owned by Mr Hirsch and Mr Silver – had changed hands in a highly confidential off-market deal.
