I have to say that I’ve noticed some very odd moves on Zillow as well. In my neighborhood, one house “went down” by $45K over the last 30 days, while an identical house a couple of blocks away “went up” by $45K. One is now valued at $800K, while the other is valued at over $1M. The funny thing is, I know both houses, and the cheaper one is the better one (better location, upgrades, etc). It seems that the grain of salt for Zillow estimates grows larger by the day.
