Big banks are not the only lenders buying up mortgage distribution. Mortgage company Resimac has revealed in its 2013 financial report that it wants to "own distribution channels" to gain better control of its "destiny".With Commonwealth Bank, Macquarie Bank and National Australia Bank investing in brokers, aggregators and other participants in the mortgage market value chain, Resimac has decided that the best way to survive in a consolidating market is to do likewise.Resimac owns 90 per cent of State Custodians, an online home loans' distributor, and 50 per cent of Finsure Finance & Insurance, an aggregator. In September, it bought Mortgage Choice's aggregator division, Loankit. The acquisition puts the company's combined aggregator businesses into the top 10 in Australia.And, in November, it finalised a scheme of arrangement to acquire RHG's mortgage portfolio, which is worth around A$2 billion.It also re-launched its own broker channel, Resimac Financial Services.The initiatives have yet to result in growth in the company's loan portfolio. The value of Resimac's mortgage book fell from $3.3 billion in the 2011/12 financial year to $3.2 billion at June 30.Income was down a little - from $50.6 million in 2011/12 to $49.7 million in the year to June.An 11 per cent increase in operating expenses and a 38.6 per cent increase in bad debt expenses hit the bottom line. Resimac made a loss of $4.5 million for the year to June.
