darpar If you list a home at say $800k and Zillow show's it at $620k you probably won't sell
it very quickly.
If you are using Zillow or anything else to ADVERTISE your home being for sale you are with the wrong Realtor.
Zillow doesn't give a shit about you or your home. They are never sending anyone over for a walk through. Zillow is not a tool that any Realtor uses.
Realtors on the other hand actually do advertise your property, they put it on the MLS. They alert other Realtors that they have a home that could work for their clients and they do open houses should a house ever not sell in 3 days.
Zillow is for daydreamers who want to look at pretty pictures in distant towns.
