An extraordinary and amazingly simple book that teaches you how to save at least tens of thousands of dollars when you prepay your mortgage, The Banker's Secret offers about forty pages of simple-to-follow text and loads of helpful charts.
Quite a while ago, I used this book to figure out what I'd need to do to pay down my mortgage faster than the required time. Then I did it.
The information must be available online now. Even so, I remember how handy it was to be able to flip back and forth in the book when it came to charts and other information. I seem to do better with a physical book when it comes to things like studying a subject. I'm not sure how I would adjust to the digital world of school work these days. Probably not well.
