Lead is measured at the water system, not the house — it cannot tell you whether a specific property has a lead service line. Radon is a ZIP-level test distribution, not a prediction for any one home; the EPA recommends testing every home regardless. Screening information only.
Sylvan Township is taxed at 34.7913 mills for a homestead (principal residence) under the official 2025 Michigan Department of Treasury millage report. On a $350,000 home at the uncapped taxable value that is about $6,088 a year.
No. All of Sylvan Township sits in Chelsea School District, so the millage is 34.7913 at every address in the municipality. Your bill still changes after you buy, because it is recalculated on the uncapped taxable value rather than the seller's capped one.
About $6,088 a year at the homestead rate. Michigan taxes the taxable value, not the sale price, and after a sale that value uncaps to roughly half what you paid — so $350,000 is taxed on about $175,000.
Because the figure on the listing is the seller's. Michigan caps annual taxable-value growth while an owner keeps the property, and that cap is removed the year after it sells. The longer the seller owned it, the further their bill sits below yours.
It is the 15 lowest of 27 municipalities in Washtenaw County and 131 of 236 across the eight-county region — 0.17 mills above the county median.
