Property Assessment- allow internal walkthrough?

[Tim LaBelle]

Hi all,

Quick back story - first time home buyer a few months ago in Milwaukee (big thanks to @Marcus Auerbach). Longer post on that process once the house projects are finished up. 

Anyway, my property assessment increased almost 40% from the last assessment (house was completely renovated), but is still $65k under the closing price. Today I received a notice stating that I should schedule a walk through with an assessor to get a more accurate assessment. Is there any benefit to me to actually going through with this? Assessments in my area definitely lag the sales prices. Any chance the assessor's process is to tack on some assumed premium without being able to verify? I find it hard to believe that my assessment would be decreased and by law I'm not required to do anything.
