Zillow

[Rushmore]

I just poked around at Zillow for an hour or so, and while I know the "Zestimates" are a little faulty and "just a guide," my home seems to have appreciated almost $200K in the past year (no, not a veiled brag, because I am very confident it's just a screwup in their "proprietary formula").

In any event, upon further investigation, I found the Zillow discussion boards where there's talk of class action lawsuits and horrifyingly underestimated home values.

Does anyone have any experience using Zillow? I obviously don't want to call my agent to see if she can explain a 25% appreciation, as I imagine she'll smell blood in the water and talk me into listing it, which I absolutely do NOT want to do.

Any Zillow advice or testimonials or horror stories or anecdotes?
