It sure looks sticky but it could also be indicative of someting like the big “ship turning” analogy. It undocks slowly takes a while to get up to speed turns back very slowy gets up to speed and docks slowly. We will need several more years to see what happens.
Price variability in no way is proportionate to ammenities. IMO the inventory doesn’t fit the real wealth spreads in our society (there are too many (600-800k and up houses). I think that post correction a relatively small increase in price will net a substaintially improved combination of location and ammenities especially as related to size of house.
