Opendoor and Zillow used to be the top iBuyers in the industry. In November 2021, Zillow Offers exited the iBuying industry and is no longer purchasing homes. When Zillow Offers was in operation, Opendoor was the better option of the two if you're interested in a quick sale. Both companies had similar associated fees, with an average of 1% in closing fees and 5% in services fees. Opendoor reviews also have a higher customer rating compared to Zillow reviews. To get the best idea of which one would have been best for you, getting estimates for each and comparing the purchase price would be a strategic move since neither company requires (or required) obligations.
