Zillow vs. Redfin
Zillow and Redfin used to have wildly different estimates on the same houses. Over the past year, I have noticed that their estimates have been converging to become very similar. What’s behind that?
One of them is just calling the other’s API
One of them (I believe redfin) reacts faster to changing market - right or wrong. When market is slower, gives time to catch up and equalize.
For on-market or off-market? Zillow at least has separate models and iirc on-market takes listing price as a fairly heavily weighted feature
Zillow has better UI and more discount
Zillow has an honest estimate history, but Redfin shifts the whole curve
Who cares. Online estimates are meaningless and only accurate plus or minus a million dollars at best lol.
The cost function was incorrect for one of them, just kidding 😂
I don’t understand why can’t Zillow Redfin modify their zestimate algorithm to look at last 30-45 days “sold” price in the zipcode for “similar” type houses rather than ridiculous zestimates which no realtor/agent anyways cares.
What do you think the Zestimate entails, if not that
Look at what happened to Zillow’s house flipping business. Their algorithms are a joke.
