This is a perfect, illustrated example of venture capital squeezing out individuals, cornering a market, and trying to extract ALL the profits from it. This sort of behavior is why housing prices have shot up nationwide. Home ownership was already under siege from underemployment, inflation, and educational loan burdens. Now we have the malfeasance of big companies trying to capture the low-hanging fruit in the housing market, which will only serve to further erode the American dream of the middle class, to the benefit of the already-wealthy. Zillow may have over-leveraged their algorithm here, but, rest assured, there are people out there doing this on a wide scale.
