Calumet Township was reassessed on the South Triad schedule for 2026 and is next scheduled for reassessment in 2029. Because it is among the county's smaller townships by recent sales volume, finding useful recorded sales may require a close review of the subject's assessment neighborhood. Reassessment timing does not restrict annual review: the Board of Review opens a Calumet Township window every year.
Evidence to review
- Keep the initial search inside the assessment neighborhood and record which physical feature makes each candidate sale more or less comparable.
- When few recent transfers fit, extend the sale period in measured steps and keep the dates visible in the comparison.
- Treat an older price as dated evidence that needs context, particularly if either property changed after the transfer.
- Compare the Assessor's land record and building record field by field rather than assuming that one accurate section validates the other.
- Label condition photographs with the date, viewpoint, and affected part of the property.
