I bought a house a year and a half ago; Zenstimates are consistently ridiculously low for my area. I was looking for single family homes in Somerville, MA. There is so little supply that every home goes immediately after listing and most likely with a bidding war. If you look at the Zenstimate for my property, it looks like I over-payed by almost 30%, but I guarantee I could flip for a profit tomorrow.
