I found out today that if you want to enter more than one house for sale, Zillow is going to charge you to list them. I don't know how much they charge because I'm not going to pay for something that 20 other sites do for free, so I didn't sign up.
I entered one of my listings and everything went fine. I went to put in the second listing and it asked my to verify my account by entering in credit card information. What? It sounds like a bad internet scam. No indication of what the charge will be. No warning that multiple listings will incur charges. Nothing. If I kept going they probably would need my social security number.
But given how horribly inaccurate zillow's entire site is, I'm not surprised.
