NAR Investigating Its Home Sales Data

Washington, DC, Feb. 22, 2011 — The National Association of Realtors is investigating the possibility that its house sales data underestimated the extent of the housing crisis, according to the Wall Street Journal.

Earlier, CoreLogic, a California real estate analysis firm, said NAR’s estimates could be off by as much as 20%.

The Journal said the overestimates may go as far back as 2007.

An over-count of home sales may mean that there is a bigger backlog of unsold homes.
