Realtors are exploiting a flaw in Zillow's Zestimate algorithm by listing homes at inflated prices to artificially boost the estimated value, causing market distortion and headache.
Zillow's algorithm can be gamed by listing a property at an artificially high price, which then adjusts the Zestimate upward, enabling manipulation of perceived market value.
