One of the more surprising stats in the latest residential home-sales data released yesterday by the Houston Association of Realtors, Swamplot’s numbers expert is kind enough to point out, is a whopping almost 40 percent drop in the number of listings that were active last January. Whazzat mean? That there were 40 percent fewer active listings this January than in January 2010? No, it’s screwier than that: The latest HAR report says that there were almost 40 percent fewer active listings in January 2010 than their own reports told us a year ago. Revising last year’s numbers down so dramatically, of course, makes it a whole lot easier for the local real-estate organization to announce at least one piece of news in this month’s press release: Listings are up 13.7 percent over this time last year!
But the new report doesn’t mention any adjustments. And it makes similar — though less dramatic — changes to last year’s data in several other categories.
