As a Realtor, I have been amazed by the arrogance of the people trying to sell you on advertising with their site. Extremely pushy and condescending. One even said if I didn't see the wisdom of signing a 12 month contract with Zillow, I must not be much of an agent. (I have closed more than $100 million).
Then when I thought I had negotiated a 6 mos contract, I discovered right at the last minute that the deal included an automatic renewal for another 6 months. Now, somebody please tell me how a 12 mos contract is different than a 6 month contract with an automatic renewal for another 6 months with the same terms? It was just their sales person doing some fast talking. Fortunately, I caught it just in time and cancelled the deal. AGENTS: Be careful with them!
