Tracking existing home inventory will be very important this year.

As of August 27th, inventory was at 431 thousand (7 day average), compared to 592 thousand for the same week a year ago.  That is a decline of 27.1%.

Compared to the same week in 2019, inventory is down 56%.

A week ago, inventory was at 431 thousand, and was down 27.3% YoY.  

Seasonally, inventory has bottomed.   Inventory was about 40.7% above the record low in early April.

A couple of interesting points from 2019:   In 2019, inventory bottomed at 814 thousand in February (so inventory is still very low compared to normal levels).   And, in 2019, inventory peaked at 972 thousand in early August (an increase of about 19% from the low).   So inventory is less than half of what we'd normally expect, however inventory has increased (as a percentage) more than normal.

Key question: Usually inventory peaks in the Summer, and then declines into the Fall.  Will inventory follow the normal seasonal pattern, or will inventory continue to increase over the coming months?  This will be important to watch for house prices and housing activity.

Altos Research has also seen a significant pickup in price decreases - now above the level of a year ago - but still well below a normal rate for August.
