A real estate appraisal is simply that -- the expert opinion of a certified, state-licensed professional who determines the value of a piece of property. If your $300,000 dream home is really worth only $200,000, then the home is overpriced. A home appraisal also protects the bank from getting stuck with property that's worth less than they've invested. And it protects you from paying too much for a house simply because it was love at first sight. The home appraisal is a no-nonsense factor in a decision that is often emotional for the buyer. A home appraisal is not the same thing as an inspection.
