This is a real clever site. Great for Realtors. If you are a homeowner listing your property, your zillow zestimates, show your property worthless. But if it's a realtor listing with the same comparable, wham o, their property is zestimated for a lot more. I have sold many properties in the past, and have never seen a site like this. I have com parables, property tax estimates, recent sales, and property appraisals, to prove this. The site is a meat market for realtors. List at your own risk in the information age.
