Seattle real estate has been trending downward for a couple years now. It isn't a single factor but the confluence of several. Initially it was only in some market segments but seems to have spread to most of them now.
The inventory of housing currently on the market is anomalously high and there are relatively few buyers. I know a few people that will be lucky to sell for as much as they paid a decade ago. People who bought during the COVID bubble are underwater.
This feels more like the beginning of a macro trend than a temporary blip.
