Does the NAR home price include distressed (foreclosure and REO) sales?
The National Association of Realtors (NAR) data is reported by real estate agents, and is not limited to "arms-length" transactions data. It will include foreclosure sales, if the foreclosed property was listed by a real estate agent; but not all foreclosure sales are so listed.
According to the NAR, in 2008-2009 about 45-50% of the sales they recorded were foreclosure sales.
("Distressed" sales include foreclosure proceedings and REOs, or "real estate owned" by banks after foreclosures. Some state associations of Realtors now break-out distressed sales.)
