Housing Inventory Tracking

Update: Watching existing home "for sale" inventory is very helpful. As an example, the increase in inventory in late 2005 helped me call the top for housing.

And the decrease in inventory eventually helped me correctly call the bottom for house prices in early 2012, see: The Housing Bottom is Here.

And in 2015, it appeared the inventory build in several markets was ending, and that boosted price increases. 

I don't have a crystal ball, but watching inventory helps understand the housing market.

Inventory, on a national basis, was up 0.5% year-over-year (YoY) in June, the first YoY increase since June 2015!

The graph below shows the YoY change for non-contingent inventory in Houston, Las Vegas, Sacramento and also Phoenix (through June) and total existing home inventory as reported by the NAR (through June 2018).

This shows the YoY change in inventory for Houston, Las Vegas, Phoenix, and Sacramento.  The black line is the year-over-year change in inventory as reported by the NAR.

Note that inventory in Sacramento was up 26% year-over-year in June (inventory was still very low), and has increased YoY for nine consecutive months. 

Also note that inventory is still down 11% YoY in Las Vegas (red), but the YoY decline has been getting smaller - and inventory in Vegas will probably be up YoY very soon.

Houston is a special case, and inventory was up for several years due to lower oil prices, but declined YoY recently as oil prices increased.

Inventory is a key for the housing market, and I will be watching inventory for the impact of the new tax law and higher mortgage rates on housing.   Currently I expect national inventory will be up YoY at the end of 2018 (but still be low).

This is not comparable to late 2005 when inventory increased sharply signaling the end of the housing bubble, but it does appear that inventory is bottoming nationally.
