I found this book to be misleading when comparing property investment options to shares (such as saying shares can only have an LVR of 50%, which is incorrect, it can be as high as 85%), selective use of time periods and criteria to favour property over other asset classes, and basic mathematical mistakes (eg in the demonstration of compound interest). The book would benefit from referencing its statistical claims, such as that there was an average Australian salary of $100,000 in 2016 - a quick google search shows that the figure is actually $79,721.
Would not recommend if you’re looking for an unbiased comparison of different asset classes.
