Here's a LINK to the GAO site for the document. The full document is also posted vai SCRIBD after the jump. Let me know what you think in the comments. Here are a couple of interesting excerpts:
In contrast with appraisals, BPOs do not have standard requirements and are generally not considered a credible valuation method for mortgage originations. According to some mortgage industry participants, a key disadvantage of BPOs is that real estate brokers and agents who perform them are not required to obtain training or professional credentials in property valuation, and the BPO industry lacks uniform standards. At least one industry group has developed standards of practice for BPOs, which are reportedly used by some BPO providers, but adherence to these standards is voluntary. Similarly, the industry has not adopted standardized BPO forms, resulting in differences in the content and quality of BPO reports, according to some mortgage industry participants. Additionally, BPOs provide somewhat different information than appraisals—a sales price or listing price rather than the property’s market value. The enterprises do not permit lenders to use BPOs for mortgage originations, and guidelines from federal banking regulators state that BPOs do not meet the standards for an evaluation and cannot be used as the primary basis for determining property values for mortgages originated by regulated institutions.
In the section with observations about AMCs, you'll find this:
- Selecting appraisers. Appraiser groups said that some AMCs select appraisers based on who will accept the lowest fee and complete the appraisal report the fastest rather than on who is the most qualified, has the appropriate experience, and is familiar with the relevant neighborhood. They said that, with many experienced appraisers departing from the industry, less experienced appraisers, who are often willing to accept lower fees, are left to perform most of the work.
- Reviewing appraisal reports. According to some appraisal industry groups, some AMCs’ appraisal reviews overemphasize how close the appraiser’s value conclusion is to an expected value generated by an AVM, at the expense of other important elements of the appraisal, such as the appropriateness of the comparable sales. One group noted instances in which AMCs told appraisers which comparable sales to use when the appraisers’ original value conclusions were not consistent with AVM-generated values.
- Establishing qualifications for appraisal reviewers. Representatives of an appraisal industry group told us that some AMC reviewers may lack the expertise necessary to identify problems with quality. They noted that in some states appraiser licensing and certification requirements do not address qualifications for appraisal reviewers.
