The article points out the correlation between rising income and rising house prices. I suspect the real cause involves both incomes and credit availability/price. Incomes are just a proximate cause - as debt serviceability improves, people borrow close to their limit, which increases. The limit increases when income increases, but also as interest rates fall.
