When Rebecca Kornman was a student at Kenyon College, she and some of her friends picked up a voyeuristic hobby. Using the Ohio liberal arts school’s student directory, they found students’ home addresses and looked them up on Zillow to see how much their families’ homes cost. They live in a brownstone, a five-story brownstone.’”“I think it's definitely more taboo the more money you have,” Kornman says. When you look up an address on Zillow, a Zestimate—Zillow’s estimate of a given property’s current value—appears below photos of the property. Zillow does not give users the option to hide their home’s Zestimate and price history.
