ANN ARBOR, Mich. Ann Arbor voters will decide whether to raise millions of dollars through a new property tax to build or acquire housing for people with certain incomes. Ann Arbor, the home of the University of Michigan, has one of the strongest economies in Michigan, although that also means higher housing costs compared to other communities. Council member Zachary Ackerman, a Democrat, said the millage could keep service workers and public employees in Ann Arbor. It would get unhealthy.Council member Jack Eaton, a Democrat, said rents could increase if the millage passes and landlords pass the tax to tenants. We need to be careful not to create a community where only the very wealthy and those eligible for housing subsidies can afford to live, Eaton said.
