im yet to see the logic and data behind their decision and ascertain if they have a new risk manager who studied under Some Economic Theorist, or if last weeks Seance rearranged the tea leaves in some shocking way.
The logic behind this decision is simple enough; more properties equates to more risk. Whilst it's counter intuative and most investors would disagree (myself included), here's the thinking of the people who set these policies...
1. Most property in Australia is negative geared when you consider rental yield vs purchase price plus costs. This means that with every property you purchase, the investors cashflow reduces.
2. The more properties you own the more risk you are of havings any individual property vacant or needing repairs, neutralising its cashflow for a time.
1 + 2 = 3, which is the more properties you buy, the worse your cashflow, plus the higher risk of additional cashflow reduction through vacancy. This directly translates to a higher risk of default by people with multiple properties (regardless of the value of these properties).
The investors arguement is multiple properties means multiple income streams, but given that from a risk managers criteria that a property is negative geared until it achieves a rental yield in excess of 12%, they've got a good mathematical argument that more properties equals higher risk.
And unfortuantely they're the ones who approve or decline loans...
... it would be interesting to see AMPs argument in the case of an investor who owns 10 IPs outright and wants a loan for number 11.
