NWMLS: Inventory up big from 2017, sales slip

Get access to the full spreadsheets used to make the charts in this and other posts, as well as a variety of additional insider benefits by becoming a member of Seattle Bubble.

October market stats were published by the NWMLS today. Home prices were basically flat from September, and inventory dropped a bit but was up dramatically from 2017. Sales continued to slip from last year as well. September’s year-over-year listing growth was an all-time record at 68 percent, but October’s 86 percent blew that out of the water.

The NWMLS hasn’t published their press release yet so let’s just get right to the data.


NWMLS monthly reports include an undisclosed and varying number of
sales from previous months in their pending and closed sales statistics.

Here’s your King County SFH summary, with the arrows to show whether the year-over-year direction of each indicator is favorable or unfavorable news for buyers and sellers (green = favorable, red = unfavorable):

October 2018 Number MOM YOY Buyers Sellers
Active Listings 4,873 -6.5% +86.1%
Closed Sales 2,052 +11.9% -15.9%
SAAS (?) 1.29 -25.5% +24.8%
Pending Sales 2,295 +2.3% -16.8%
Months of Supply 2.37 -16.5% +121.3%
Median Price* $670,999 +0.4% +6.5%

Here’s the graph of inventory with each year overlaid on the same chart.

Here’s the chart of new listings:

New listings were up five percent from a year ago, but began the usual seasonal decline month-over-month.

Here’s your closed sales yearly comparison chart:

Closed sales rose 12 percent between September and October. Last year over the same period closed sales dropped three percent. Year-over-year closed sales were down 16 percent.

The Seattle Times hasn’t posted their story yet. I’ll probably update this post when they do.
