County seat: Mount Clemens
Macomb carries a dense mix of industrial and flex space along the M-59 and Van Dyke corridors, retail strip along Gratiot, and a large base of post-war residential stock. Industrial and flex buildings here are frequently assessed off cost figures that have not tracked what the space actually rents for.
County seat: Pontiac
Oakland has the region’s largest concentration of suburban office, along with substantial retail and a wide residential range. Office values have moved considerably since the assessment methods behind many current figures were set, and multi-tenant buildings with real vacancy are often carried as though they are full.
County seat: Howell
Livingston mixes newer residential subdivisions with commercial and light industrial development along the I-96 and US-23 corridors. Rapid development means comparable evidence is uneven, and an assessment set against the wrong comparables can stay wrong for years.
County seat: Port Huron
St. Clair carries industrial and waterfront property alongside a broad residential base. Waterfront and special-purpose property is difficult to assess with ordinary comparables, and that difficulty shows up in the numbers.
County seat: Ann Arbor
Washtenaw has a strong income-producing base, including multi-family and mixed-use around Ann Arbor and Ypsilanti, alongside commercial along the I-94 corridor. Income-producing property is assessed on assumptions about rent and vacancy, and assumptions are exactly the kind of thing evidence can test.
County seat: Lapeer
Lapeer combines agricultural land, small-town commercial, light industrial, and rural residential. Thin comparable evidence is common, and a thin evidence base is a weak foundation for an assessed figure.
County seat: Flint
Genesee carries substantial industrial and former industrial property, commercial along the I-69 and I-75 corridors, and a wide residential range. Values differ sharply between communities within the county, which makes the choice of comparables decisive.
