Sharing from their own personal experience in the power of Commercial property in Australia, I found this book a very good basic foundation in Commercial property, the power of it, and understanding how you might first approach it.
It did make me consider commercial property, after others I have read have promoted residential, which I know is a more competitive market.
It was simple and clear, and the writing felt like it was promoted with a sense of wanting to share their success (able to retire at 28 years old is a pretty solid endorsement to me!). They do mention some of their services that they provide, but overall it is written to empower you to know what you need to do to do it yourself, and that their help is there is you find you need it at some point.
