It is a loan which does not require you to provide the same amount of documentation in order to get the loan as you would with a normal mortgage ie financial statements, tax returns. They may not be interested in your salary and may take your investment income into account instead/as well as. For this you pay a premium on the interest rate. I’m in the process of getting one at 7.25% to 90%LVR with no mort. insurance. Approved in 24 hours subject to valuation.
