New Home Supply Falls To 16-Year Low

New Home Supply March 2010-March 2011After posting an all-time low in February, New Home Sales rebounded strongly last month.

Based on joint research from the Census Bureau and HUD, 300,000 new, single-family homes were sold on a seasonally-adjusted, annualized basis in March. It's an 11 percent improvement from February, and right in-line with the 6-month average.

The supply of available new homes improved, too, in March, falling by close to a full month.

At the current pace of sales, the entire new home housing stock would be sold in 7.3 months. This is the second-best reading in a year, a statistic partially-supported by the relatively small number of new homes on the market.

There are now just 183,000 new homes available for sale. That's the smallest reading since the Census Bureau started to keep New Home Sales records beginning in 1995.

However, it should be noted that the March New Home Sales data is suspect. The reading's margin of error exceeds it actual measurement by almost double. It's possible that sales volume fell in March instead of rising, therefore. The Census Bureau says as much in its footnotes:

The change [in new home sales] is not statistically significant; that is, it is uncertain whether there was an increase or decrease [in March 2011].

We won't know for certain until future data revisions are made.

If you're a home buyer , though, and want to stay ahead of the market, you won't want to take chances. If the Census Bureau finds its data to be accurate after revisions are made, new home prices will already have started to rise.

You may get your best home value by buying sooner rather than later.

Housing Starts Rise In November, But With A High Margin Of Error

Housing Starts Dec 2008-October 2010The number of single-family Housing Starts increased in November, adding 30,000 units as compared to October.

The Census Bureau defines a "housing start" as a home on which construction has started.

November's starts represents a 7 percent increase from the month prior. However, if you see the Housing Starts story online or in the papers, you'll notice that the press is calling the market gain at 4 percent.

So which result is right? The answer is both.

The government's monthly Housing Starts data is published as a composite report; lumping activity among 3 separate housing types into a single, group reading.

The 3 housing types are:

  1. Single-family homes (i.e. 1-unit)
  2. Multi-unit homes (i.e. 2-4 units)
  3. Apartments (5 units or more)

The group reading is a fair description of the market and it's easy-to-understand. As a result, it's what the press tends to report. However, for home buyers in utah , it's the single-family category that's most relevant.

 

The reason why single-family homes accounted for 84% of November's Housing Starts is because that's the type of home that most buyers buy. Few purchase 2-4 unit properties, and even fewer buy entire apartment complexes.

That said, it's possible that November's Housing Starts data is wrong. Within the press release, the government placed an asterisk next to the data, indicating that the figure's margin of error exceeds its actual measurement.

Against a 7 percent gain, the reported margin of error is 13.5%. There is no statistical evidence, therefore, to prove the actual change was different from zero.

If Housing Starts did fall in November, it will help to reduce the housing inventory, which will, in turn, help keep home prices high. For home sellers, this could mean good news. Fewer homes for sale increase competition among buyers.
