According to the study, despite all the claims by Fannie and Freddie, touting the benefits, research of the effects since implementation is nearly non-existent. The authors claim this study is the first empirical examination of the impact of the first major appraisal rule, the now sunset, Home Valuation Code of Conduct. It measure the share of "low" appraisals (as compared to the purchase price) from the first quarter of 2006 through the third quarter of 2012. There is also a chart on page 23 of the study showing the distribution of high and low appraisals pre- and post-HVCC. The study defines Significantly High Appraisals as those 5% of more above the contract price, and Significantly Low Appraisals as one which is at least 5% below the contract price.
One aspect of appraisals NOT examined pre- and post-HVCC, is appraisal quality.
