In depth and easy to understand
Format: Paperback
I am an active investor and have read quite a few books on a variety of investing and real estate topics. Accordingly I mostly skim new books and try to strengthen concepts I am already mostly comfortable with. I previously had difficulty grasping irr, npv, and dcf, and this book explained these thoroughly, simply, and with examples that will allow me to use these tools to make better investing decisions. I think this book will offer great value to those just getting started and those at a more advanced level alike.

Thinking about investing in Real Estate? READ THIS FIRST!!!
Format: Paperback, Format: Paperback
I now have a new favorite real estate investing book. Real Estate by the Numbers has now been added to my permanent investing collection of must-reads. I bought Frank's book, similar topic, 20 years ago as I began my then "casual" interest in investing. I find J & Dave's book more accessible with anecdotal stories that help deliver the content in an easy-to-grasp style for both newcomers and existing real estate pros alike. Know anybody seeking financial freedom through real estate investing? Buy them a copy of J &Dave's new book (or both)!
