Recent numbers are changing massively, sometimes weekly, with no basis in fact.
For example, a house across the street from me, two doors down, just dropped from $590k to $520k over the past week with the entire past history price chart revised as if the high valuation (which was consistent over many months prior) had never existed.

The strangest and most clearly defective part is that this house sold last month, just closed and the new owner moved in over the past weekend. The sale price was $588k. How could it suddenly be worth almost $70,000 less? It can't. Zillow is calculating on defective formulas, using bad data and is unreliable and dishonest in reporting past valuation and valuation trends.
