Best REI book you personally have read.

[John Pestorich]

I hate the antcipation of waiting for a new book to come in the mail and after reading through it realize it is just regurgitated material.
I love to read investing books and want to know which book was most informative, aspiring, or helped you in your REI career and why.

[Jon Holdman]

I will say there is no "best" RE (or any other topic) book. I just went and counted 30 books and thats only in the two spots where I can easily find them. Doesn't count the ones scattered around the house. Some are very specific to particular aspects of real estate investing, some are like RDPD, some are more purely investing in general, and some, like the 2006 International Residential Code, are specific to construction. All are relevant. When I go to a book store (not as much now that the wife has a Kindle) I still thumb through the RE and investing books looking for something interesting. Don't try to read just one book and think that will tell you what you need to know. Read a lot of different books. Always be looking for something new and interesting.
