What’s the current market value of your home? 
That simple question has probably the single most effective call-to-action in real estate history. Every real estate transaction depends on accurate property valuations, and the Comparative Market Analysis (CMA) is the foundational tool agents use to create and present them.

The Art of the CMA, 2nd Edition is the practical, proven playbook top agents use to win more listings with better CMAs — written by Greg Robertson and Charles Warnock, and published by Giant Steps Publishing.
