Mortgage funder RedZed Lending Solutions aims to become a more frequent user of the debt capital market, with the Melbourne-based firm in the throes of marketing its third series of mortgage-backed securities.The firm plans to sell A$200 million in non-conforming RMBS through RedZed Trust Series 2015-1.RedZed managing director Evan Dwyer said: "We've been steadily building to become a regular issuer, we would like to do one every 12 months."The firm completed its first placement of RMBS in late 2011. It last sold $150 million in bonds in May 2014.Dwyer said RedZed had originated $1 billion in loans since it started nearly a decade ago."This transaction looks like it will attract new investors and we'll get a better margin than last year," he said.In 2014, RedZed priced the senior tranche of bonds at 115 basis points over the bank bill swap rate.Dwyer said he did not care for definitions of the firm's loans as prime or otherwise, but its niche is targeting borrowers not so well served by banks."I would say in our mix, eight to ten per cent of people have got a default, so 90 per cent are self employed people," he said.
