The 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 Ohio , 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 Cincinnati 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.

The number of single-family Housing Starts rebounded in August, climbing 4 percent from July’s 14-month low.

A “Housing Start” is defined as a home on which construction has started and the August increase represents 18,000 single-family units nationwide.

If you only read the headlines, however, you would think the data was stronger. This is because the Housing Starts data is actually a composite of 3 types of homes — single-family, multi-family, and apartments — but  the press tends to lump them all three together.

As a sampling, here are a some headlines on the story:

• US Stock Futures Rise After Housing Starts Surge (WSJ)
• Housing Starts At 4-Month High, Hint At Stability (Fox)
• Housing Starts Jump 10.5% In August (Marketwatch)

Now, it’s not that the news is wrong, per se, it’s just not necessarily relevant.  Few home buyers  in Cincinnati are buying multi-family homes or entire apartment complexes. Most buy single-family and, for the first time since April, single-family starts are on the rise — just not by as much as you’d believe from the papers.

Even still, we can’t be entirely sure that the August Housing Starts data is accurate anyway.

A footnote in the Department of Commerce report shows that, although single-family starts are said to have increased 4 percent, the data’s margin of error exceeds its actual measurement, meaning the data has “zero confidence”.

In other words, starts may have dropped in August, but it’s something we won’t know for sure until revisions are made later this year.

Single-family Housing Starts eased lower last month, falling by 0.7 percent from May, or 3,000 units nationwide.

A “housing start” is a home on which construction has started.

June’s Housing Starts data is somewhat soft and may partially explain why home builder confidence dropped to its lowest level since April 2009, but for buyers and sellers in Cincinnati , the Housing Starts report is not nearly as bad as headlines say.

This is because when the press reports on Housing Starts, it doesn’t single out single-family homes. The press lumps every type of home into a single, giant reading. As a result, news outlets are reporting Housing Starts down 5 percent — a somewhat misleading figure.

The 5 percent figure is actually a combination of 3 separate housing types:

1. Single-Family Housing Starts
2. Multi-Unit Housing Starts (2-4 Units)
3. Apartment Building Housing Starts (5 or more units)

But, single-family homes are what most Americans purchase. This is why the single-family starts data is more relevant than the combined figure commonly reported by the press. 2-4 units and apartment buildings are a different realm of buyer.

That said, though, we can’t even be sure that June’s Single-Family Housing Starts report is accurate. As noted in the Department of Commerce’s press release, the data’s margin of error is 10.7 percent which means the reported results are of “no confidence”.

In other words, there is no statistical evidence to prove the actual change was different from zero.

If Housing Starts did, in fact, drop in June, it will help to reduce the Indian Hill housing inventory, which will provide support for local home values. For home sellers, this could be good news. Fewer homes for sale means less competition for buyers.
