In reporting on their last contract that went into settlement or was terminated over the period June–August 2016, respondents indicated that 64 percent of contracts were settled on time, 30 percent had delayed settlement, and six percent were terminated, according to the August 2016 REALTORS® Confidence Index Survey Report.
Among contracts that had a delayed settlement (30 percent), issues related to obtaining financing, appraisal, and home inspection were the primary causes of the delay. The fraction of delays due to appraisals has increased in recent months, in part due to a shortage of appraisers and other issues reported by REALTORS® (e.g., being asked to make “inspections”).
Among contracts that were terminated (six percent), issues related to home inspections, obtaining financing, and appraisals were the major causes of termination.
