I have different problems. Zillow's estimate is about 15% higher than Redfin for us. But there's also issues with the facts each have about our home. Zillow's estimate also goes up and down by tens of thousands of dollars per week. Some weeks it'll be as much as a $40,000 swing.
Keeping the data correct on the sites is also a chore, and if I don't keep on top of both sites, entire rooms or bathrooms will come and go, square footage will change and so on.
Real estate agents will claim that appraisers don't go off of these sites, but buyers will use them as pricing information so it almost becomes critical for home owners to police these sites to get as favorable an estimate as possible.
