Tax assessment decreased in error

[Brian Johnson]

I own a quadraplex and the county just did a reassessments of tax values.  Mine just dropped from 150k to 50k.  Everyone else in the county is complaining that their assessments went up by 75%-100%.  I was expecting mine to go up to between 250k-300k.  After looking over the assessment it looks like they entered a dwelling value of $0.  The question is should I reach out to the county tax assessor and point out their error?  or should I just enjoy the good luck until the next assessment?
