The federal government regulates appraisers indirectly because if the Appraisal Subcommittee (ASC) of the Federal Financial Institutions Examination Council (FFIEC) finds that a particular state's appraiser regulation and certification program is inadequate, then under federal regulations all appraisers in that state would no longer be eligible to conduct appraisals for federally chartered banks. The ASC oversees the TAF. Banks make widespread use of mortgage loans and mortgage-backed securities, and would be unable to do so without appraisals.
WertV's general regulations are further supported by the Wertermittlungsrichtlinie (abbr. WertR, "directive on the determination of value"). The WertR provides templates for calculations, tables (e.g., economic depreciation) and guidelines for the consideration of different influences. WertV and WertR are not binding for appraisals for nonofficial use, nonetheless, they should be regarded as best practice or Generally Accepted (German) Valuation Practice (GAVP).
