Zillow calls them zestimates for a reason – it is not a firm number, but a range. I agree, the zestimates are sometimes wrong, but more often they overvalue a house rather than undervalue it. As far as posting what the owner (s) have paid and how often the house has been sold, I think Zillow does a good job.
Zillow is not perfect, but combined with county records we have a better picture of what’s going on out there.
Heaven help us all if we have to go back to depending on what agents have to say. We need more transparency in RE, not the vagueness and deceit that we’ve had in years past. I wonder if this NCRC group has ties with NAR?
