content: I don't recommend this book due to many incorrect observations and information noted in the chapters. I was very surprised that this book was recommended by other readers because there were many mistakes and errors in the book. Some important topics were discussed incorrectly and others were too brief. To find out and confirm this I gave this book to several local real estate contractors and they pointed out many other errors in this book that even I was unaware of. They explained to me how many things discussed in the book were outdated or not relevant.
