As a renter, I hope landlords read this book. I was surprised at a few of the tips mentioned in the review - things that I know of very few landlords who follow these tips. It could reduce the liability substantially for landlords, and make the renting experience easier for the renters.
The community I live in has our states flagship University, so the idea of creating a passive income stream by owning rental properties is popular here. Passive income streams still have to be managed, though. This book sounds like a good start to understanding that.
