Chapter 70.32(1) Wisconsin Statutes

(1) Real property shall be valued by the assessor in the manner specified in the Wisconsin property assessment manual provided under s. 73.03(2a) from actual view or from the best information that the assessor can practicably obtain, at the full value which could ordinarily be obtained therefore at a private sale. In determining the value, the assessor shall consider recent arm's-length sales of the property to be assessed if according to professionally acceptable appraisal practices those sales conform to recent arm's-length sales of reasonable comparable property; recent arm's-length sales of reasonably comparable property; and shall all factors that, according to professionally acceptable appraisal practices, affect the value of the property to be assessed.
