Tracking existing home inventory is very important in 2022.

Inventory usually declines in the winter, and this is a new record low for this series.

As of February 18th, inventory was at 248 thousand (7-day average), compared to 334 thousand for the same week a year ago.  That is a decline of 25.8%. 

 A week ago, inventory was at 250 thousand, and was down 27.5% YoY.    

Inventory was down 0.7% from the previous week.

Compared to the same week in 2020, inventory is down 65.7% from 723 thousand.

Last year inventory bottomed seasonally in April 2021 - very late in the year - usually inventory bottoms by February. An early key in 2022 will be to watch if inventory bottoms earlier this year.

And here is a table of the year-over-year change by week since the beginning of the year. A possible early indicator might be if the YoY decline is less each week.

Week Ending	YoY Change
12/31/2021	-30.0%
1/7/2022	-26.0%
1/14/2022	-28.6%
1/21/2022	-27.1%
1/28/2022	-25.9%
2/4/2022	-27.9%
2/11/2022	-27.5%
2/18/2022	-25.8%
