unexplained Zestimate decrease, changed historyWe purchased our home (6 Longwood Road, Milton, MA 02186) in Oct 2009. Through most of 2011 Zillow has valued it (Zestimate) between $630k and $670k. Very recently the Zestimate dropped in significanty to around $610k and now to $583k. The history has been adjusted too, maxing out at $630k for 2011. Other homes on our street have not seen similar activity. Also, there have been a few comparable home sold in the immediate area that should, in theory, raise the value. Can you offer any insight as to why this may be happening? We are currently doing a first floor overhaul that we would expect to push the value higher.
