The 160-page study — known as the DANGER report (, or the Definitive Analysis of Negative Game Changers Emerging in Real Estate — was commissioned by NAR’s “strategic thinking advisory committee” and authored by industry consultant Stefan Swanepoel of the Swanepoel /T3 Group. It is based on a survey of 7,899 Realtors and interviews with 74 top realty chief executives, plus additional research. Other problem areas it details concern multiple listing services, state Realtor associations and NAR itself.
