I spent some time this weekend compiling a giant spreadsheet of every active listing in all of King, Snohomish, and Pierce counties, so if you don’t like the interactive Tableau maps, this probably isn’t going to be your favorite week.
First up, let’s have a look at a map of the “staleness” of listings. The map below has a circle for every zip code with at least five listings. The circles are sized according to the number of listings, and color-coded based on the “staleness” of the listings. This is based on the original listing date, not the latest time the agent pulled and re-posted the same house.
Zip codes near the market-wide median of 92 days on the market are grey, above the median is blue, and below the median is red.
Here in King County, Medina (98039) has the most stale listings, with the median days on market coming in at 149. Of the zip codes with over 100 listings, West Seattle (98116) takes the cake with 129 median days on market for its 181 listings.
The freshest listings in King County are in downtown Seattle (98101), at just 54 median days on market. The north Seattle neighborhoods of Ballard (98107), Fremont/Greenlake (98103), and U District (98105) all came in well below the median as well, at 55, 74, and 63 respectively.
King and Snohomish County both had a county-wide median days on market of 90, while Pierce was slightly higher at 95.
