As an appraiser I am very aware of poor or lcanikg data on MLS information sheets. I am in central Wisconsin and some data, such as age of a property, is only availabe from assessors who mostly work out of their homes and do not have web sites. When we get orders with short turn times we sometimes can’t find the assessor. It is such a simple process for brokers, who typically have weeks of time to get this info prior to sale but do not bother. We also have a problem with brokers referring to manufactured homes as one story and no mention that it is a manufactured home because they do not want buyers to shy away from them.
