how many could afford a 50% increase, page-4

"if they are currently at 5% and rates rise to 7.5%.. there would be major mortgagee sales..."

it went to 9% after GFC, and what happened then??
Hardly moved defaults. You are doomed to failure if you can't learn from basic recent history.

Banks have reported people paying more off mortgages, and are ahead on payments more than anytime in history. You would be surprised by the resilience of folks holding onto the PPOR.

A small minority with unusual circumstances will default at anytime. Australia remains at globally very very low rates of default.

Your claim (big claim too) there would be "major mortgagee sales" at 7.5% is tenuous at best and poorly thought through.

I'd suggest you are pandering to the bears again with this nonsense Rebel.
