Home Values Up 0.4 Percent In August, On Average

Consistent with the most recent Case-Shiller Index, the government's Home Price Index said home prices rose between July and August. 

The Federal Home Finance Agency's data showed values up 0.4 percent nationwide, on average. Region-by-region, however, the results were scattered. Coastal states tended to perform poorly. Plains states tended to perform well.

A brief look at the regional disparity:

• West South Central : +1.5%
• East North Central : +1.2%
• Pacific : -0.2%
• South Atlantic : -0.2%

Breakdowns like this are important because they highlight the fundamental problem with national real estate data and that's that home buyers in Corona don't buy real estate in a national market, or even a regional one.

Buyers buy local.

When we look at national figures like the Home Price Index, it's important to remember that real estate is a collection of tiny markets which, when lumped together, form small markets which, in turn, lump together into larger markets and so forth.

To illustrate this point, a deeper look at August's Home Price Index data shows that, within the aforementioned Pacific Region, in which home values fell 0.2%, the state of California posted a 2.9% increase. You can be sure that within the state of California, there are cities that performed better than the 2.9 percent, and within those cities, there are neighborhoods that did the same.

Real estate is most definitely local.

That said, we can't discount the national report entirely. Broader housing statistics like the Home Price Index reflect on the economy and are often used to help shape policy in the nation's capital. When you need to know what's happening in your hometown, though, your best source of data is a knowledgeable real estate professional.

The Home Price Index Shows Some Regions Up, Some Regions Down

Earlier this week, the private-sector Case-Shiller Index showed home prices slightly lower between November and December.  Thursday, the public-sector Home Price Index showed the same.

Publishing on a 2-month lag, the Federal Home Finance Agency said home prices fell by 1.6 percent nationally in December.  And that's an average, of course.  Some regions performed well in December as compared to November, others didn't.

• Values in the Middle Atlantic states improved slightly
• Values in New England were essentially unchanged
• Values in the Mountain states sagged, down 3.5%

These aren't just footnotes. They're an important piece toward understanding what national real estate statistics really mean. In short, "national statistics" are just a compilation of a bunch of local statistics.

For example, if we dig deeper into the FHFA Home Price Index 70-page report, we find that cities like Terre Haute, IN, Buffalo, NY, and Amarillo, TX posted year-over-year home price gains. You won't see that in a "national" report.

Furthermore, it's a sure bet that those same cities, you could find neighborhoods that are thriving, and others that are not.  Just because the city shows higher home values overall, it won't necessarily be the case for every home in the city.

Every street in every neighborhood of every town in America has its own "local real estate market" and, in the end, that's what should be most important to today's buyers and sellers.  National data helps identify trends and shape government policy but, to the layperson, it's somewhat irrelevant.

So, when you need to know whether your home in Corona is gaining or losing value, you can't look at the national data.  You have to look at your block -- what's selling and not selling -- and start your valuations from there.
