Take a look at an actual example of a home estimate from 5 different estimation websites. IT'S THE SAME HOUSE, TAKEN ON THE SAME DAY! After over 30 people viewed the home in the first 5 days, on the 6th day we received 1 offer. The home sold for full price at $589,900. That's called "true market value". None of these online estimates were even close. Do you now see that these are absolutely worthless?
