Wis. Admin. Code Department of Safety and Professional Services SPS 85.500
Under federal law, a financial institution is responsible for making the final determination of whether an appraisal is complex. A financial institution may presume that appraisals of 1-to-4 family residential properties are not complex, unless the institution has readily available information that a given appraisal will be complex. If during the course of the appraisal a licensed appraiser identifies factors that would result in the property, form of ownership, or market conditions being considered atypical, the financial institution must either ask the licensed appraiser to complete the appraisal and have a certified appraiser approve and cosign the appraisal, or engage a certified appraiser to complete the appraisal. 12 CRF 225.63.
