My parents recently moved cross country. Last summer, they contacted and met a real estate agent in the area they were planning to move to.
The property they eventually found was not due to the hard work of their agent, but due to a Zillow listing. The house had been on the market for roughly four months and owners were just about to de-list it. It was exactly what my parents were looking for, and in the price range they had given to the agent.
I’m not why you think Zillow is so evil, but for my folks, it worked to their benefit.
They way you used it is exactly how it should be used. Private owner, FISBO and Zillow put the seller and buyer together. I'm all for that.
But Zillow is demanding from the courts proprietary data, their business model is to leech/commandeer data from others- who worked for it.
