Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub.

Insightful, funny, but a bit unforgiving
This book is an absolutely no holds barred guide for preparing a current/future Section 8 Landlord for difficult situations and tenants. The authors own over 300 rental properties and prefer to remove anything and absolutely everything not strictly required for passing a property inspection. This means ripping out things like screen doors, washing machine hookups, dishwashers, etc. Following their method, you end up with a relatively spartan property that easily passes inspection. They're a bit light on the empathy side, but overall, this is still excellent business advice. The writer is also really funny and some of the anecdotal stories are great. Definitely worth the money! The only reason I'm giving it 4 stars is the Diversified Real Estate Investor Group papers (written by James M. Bennett) in Chapter 18 are incredibly difficult to read on a kindle (see the picture). Otherwise, this is a 5 star book full of excellent advice.

Nuts and Bolts of Section 8 for Landlords
Format: Paperback
Learned so much from this book. Lots of practical information and entertaining to read. I bought all of the books by this team of do-it- your-selfers. They even include access to a rental contract they advertise as ironclad.

Very open. No BS

I normally dont give reviews unless the product is exceptionally well. I am learning and will enter into this area of real estate thanks to this book series. I have read and highlighted the hell out of book one. Because, of the plain talk this book is written in make it easier to understand. Great job. After I finish all 3 of these. I will order the other. Thank you for sharing you knowledge, expertise and experiences. You really tell people the truth and I wasn't expecting that. I was expecting some truth with alot of BS. You delivered.

Great, Practical, Real
Format: Paperback
Finally a real estate book that has real, practical tips and methods to go out and get deals done. I almost didn’t read this as in the last few months I have poured through dozens of books and got sick of the “have a solid goal and motivate yourself” or the “this is why real estate is a great investment” that plagues 99% of books in this area while providing no real context. This book should have been my first go-to book. It’s real, authentic, full of real world advice and tips. Read it and you finally get an idea of how to do it from the guys who actually do it. This isn’t a “feel good” book written by an author or journalist. It’s a practical, raw, real-world guide to Section 8 real estate from the guys who have hundreds of units. A must read
