I know exactly what Zillow does and there isn't much difference from them or the folks emailing you, calling, you, texting you, mailing you and haranguing you on social media, TV, Radio, streaming, and how bout those billboards. Corporations unraveling our lives. It allows most people to not make good decisions. It like you have a chest pain and simultaneously, every cardiologist is haranguing you, sending pics of them & their family, talking community family work & there support for habitat for humanity. Anything that rises them to top and fool you with fast talk. Doesn't take much to fool the public with these overly nasty marketing concepts that everyone doesn't seem to much to mind. BTW, for most people, using something like Zillow is like you need heart surgery and after watching you-tube all night, you decide you are qualified to give the cardiologist tips. AS always, your going to most likely use a Realtor for a home purchase, why not, use their professional understanding of the market and take advantage instead of letting your emotions run the game, from the start? A good Realtor levels the field of emotion and helps you make the intelligent decision you want to make. Otherwise, you get a money hunger Realtor, staring at yours & their pocketbook, aggressively looking for the next sale. Its the sale they want more than you satisfaction cause now, they get less compensation, splitting with these corporations. Hey call it how you like it, but don't call it good. Freighting is a better wordZillow allows the homeowner to make adjustments for "unseen" improvements, but there will still always be some disconnect from reality.
