The Real Estate Investor's Pocket Calculator by Mark Lewis Taylor (2005, Paperback)

This book gives you simple ways to compute cashflow, value, return, and other key financial measurements fast and easy in the investor's hands. This book gives you the same tools real estate agents use to calculate yield, values, taxable income and operating expenses.

All different types of values are revealed in chapters which cover everything from acceleration techniques and methods for reducing interest to ways of maximizing investment returns. Worksheets, tables and charts provide clarity and all the formulas needed to succeed. Very highly recommended as an essential, basic pick any real estate investor should keep at hand. I converted most of these formulas to Xcel spreadhseets that I use on my home computer.

Give yourself an unfair advantage and keep this book as a pocket reference guide that you carry with yourself at all times.
