Zestimates Don’t Do Walk-Throughs

Automated Valuation Models (AVMs) like Zillow’s Zestimate promise instant numbers, but speed doesn’t equal accuracy. Even in well-documented markets like Phoenix, AVMs can be off by 2%–6.5% for on-market homes and nearly 10% for off-market ones—a swing of tens of thousands of dollars on a $300,000 property.
