Income from a family trust?

Hi, my situation is i am currently in the process of hunting down my first IP in the range of $220000-$260000. I am going halves with a partner who is full-time employed and satisfies all the loan requirements of the bank, however as I am a full-time uni student I have submitted my income details as the distributions I receive each year from a family trust. Whilst I do not receive any group certificates or tax returns from this distribution I have a signed statement from my accountant stating I receive, and will continue to receive, these distributions. However the mortgage broker I have consulted has been rejected by Suncorp and ING on the basis that they need more proof, in the way of group certificates, that I receive this money.

Without going into details of the family setup, it would cost my parents a sizeable amount of money (due to work on the accountants behalf) to draw up group certificates, tax returns etc to satisfy the ‘tick-the-box’ requirements of the lenders.

My question is does anyone know of any lenders that are particularly flexible when it comes to these sort of things. Both my friend and I can show a 5% savings history over the past six months and have all the deposit and closing costs covered- the only issue is finding a lender who will cover my half of the loan.

Thanks in advance, Joel.

PS My parents are also willing to guarantee my loan.
