Oakland County's Apportionment of Local Tax Rates:
Cities traditionally have a much higher millage rate than townships due to their requirements to maintain public streets, and typically to have DPW's for servicing water/sewer
Page 17 out of 34 in the .pdf covers Auburn Hills. Or page 11 of the printed copy
total non homestead millage is on average in the low 50s - of that amount, 10½ mills is allocated to local city government.
as I stated, the majority of property taxes go towards other allocations than local government.
so, for each $1,000,000 in Taxable Value that is at risk/reduced due to litigation the city budget has $10,520 at risk whereas the total property tax bill at risk/reduced is ~$52,000 (a property tax mill = $1 per thousand of Taxable Value. Taxable Value can not exceed SEV, which is intended to represent 50% of True Cash Value) of the total city budget, most often public safety, code enforcement, and the like see the lion's share of budgetary allocations rather than the assessor or treasurer's office.
due to the huge case load pending at the Michigan Tax Tribunal - most full/entire tribunal cases have 3-6 years at issue in one trial. any favorable judgment for a petitioner includes a pretty decent interest allocation on top of the tax savings.
now perhaps you can see why it would be profitable to appeal those complex / high valued properties and for a local community to simply roll over when the majority of tax dollars at risk are not their own...
