So the house next to ours is up for sale. 249 days ago, it was listed at $249,000. Then it was at $235K, then $225K, then $215K. Now it's down to $208K. So my Zillow value could have been going down, but it didn't. But now they are developing the lot next to that house. That house will probably be listed at $339,000. If the same law applies, will it go down? It doesn't matter to us a ton because we aren't going to sell anytime soon, but I just love all the math that goes into a house "value!"
Of interest to me and hopefully at least one other person
