Weekly Update: Existing Home Inventory down only 1.0% year-over-year on Oct 14th

Here is another weekly update on housing inventory: One of key questions for 2013 is Will Housing inventory bottom this year? Since this is a very important question, I'm tracking inventory weekly in 2013. 

There is a clear seasonal pattern for inventory, with the low point for inventory in late December or early January, and then peaking in mid-to-late summer.

The Realtor (NAR) data is monthly and released with a lag (the most recent data was for August).  However Ben at Housing Tracker (Department of Numbers) has provided me some weekly inventory data for the last several years. This is displayed on the graph below as a percentage change from the first week of the year (to normalize the data).

This graph shows the Housing Tracker reported weekly inventory for the 54 metro areas for 2010, 2011, 2012 and 2013.

In 2011 and 2012, inventory only increased slightly early in the year and then declined significantly through the end of each year.

Inventory in 2013 is increasing, although still 1.0% below the same week in 2012.

This strongly suggests inventory bottomed early this year, and I expect inventory to be up year-over-year very soon, and I also expect the seasonal decline to be less than usual at the end of the year.  Inventory is still very low, but this increase in inventory should slow house price increases.
