Plymouth homeowner challenges $581,400 assessment, cites misclassified details and disputed comps

A Plymouth homeowner told the Marshall County administrative hearing on Nov. 18 that the county’s $581,400 assessment for 15440 Menominee Drive is inflated and asked the board for a reassessment to $489,300 or less. The petitioner said the 2025 assessment represents a 19% single-year increase and nearly a 30% rise since she bought the home in 2023, despite no major improvements.

The petitioner, identified in the record as Miss Good, said assessor records contain errors — including an incorrect bedroom and bath count, a misidentified outbuilding and an inappropriate "grade A" classification — and that several comparables in the assessor’s report were duplicated. "The assessors have set the evaluation at $581,400," she said, and presented 15 alternate comparables she said better match her home in age, size and condition.

County assessor staff and representatives responded that assessors performed a site review and that the county uses a cyclical review every four years plus an annual sales-ratio analysis to align assessed values with market sales. Edward Leary and other county staff described driving by and photographing the property and explained that observed exterior improvements in 2024 informed a higher condition rating. The county explained the statutory sales-ratio review seeks a median assessment level between 90% and 110% of sales and that recent sales across the area have pushed valuations upward.

The petitioner cited online valuation tools and market data to argue the assessor’s number is inconsistent with local trends, saying that sites such as homes.com and Redfin show lower valuations and, in Redfin’s case, a reported 21% local decline in sale prices. She also pointed to photographs and a 2023 inspection report showing deferred maintenance — a 20‑year‑old roof, a water heater more than 30 years old and cracking sidewalks — and said exterior paint work was a repair, not an upgrade.

County staff said automated valuation models vary, but that mass-appraisal practice relies on actual sales events and a comparative grading schedule. Staff asked the petitioner to provide current interior photographs if she wanted the county to reconsider the condition grade, and they noted that individual sales do not automatically trigger a reassessment; rather, countywide market shifts and mass-appraisal techniques dictate adjustments.

The hearing record reflects testimony and documentary exhibits from the petitioner and questioning from county representatives, but the transcript does not record a final ruling or vote by the board on the appeal. The board thanked both parties for their testimony and concluded the proceedings for this case.
