I purchased this CD (and book) to listen to while I was rehabing a house to rent out. I was expecting a turn key guide - I just didn't get that from this CD or the book. This book and CD had some good info but not detailed enough for me - a lot of very high level, very basic, common sense information. I'm shocked to read so many positive reviews on both the CD and book. I have been a landlord for 10 years and own many properties. I wanted to use this CD and book to tap into the lease-options market - I will need to keep researching. I am actually a little upset I purchased the book and CD - it was too expensive for what I got - there just wasn't any substance to take the first steps.
