Zestimate, CMA, or Appraisal: Your Kennesaw Home's Real Value

You pull up Zillow and see one number. Your county tax bill shows another. Then a lender orders an appraisal and a third number appears, sometimes thousands apart from the first two. If you're getting ready to sell in Kennesaw, Acworth, or Marietta, knowing why these figures disagree, and which one actually controls your closing, matters more than any single number by itself.
