Reading the article and the threads below, I have to wonder if there's something unique to Detroit or other areas of the country exploring this land value taxation concept... for example, in my (WA) residential tax statement, there's already a breakdown of the value of the land from its enhancements (IE: my house). Similarly, an alfalfa field (bare land) is going to be taxed at a different rate than that same field having been rezoned as residential and ready for the construction of 200 new homes. That same lot, zoned commercial in the middle of our little town, would have still another tax rate. The state of Oregon is even so kind as to tell you both the value at which they are taxing your property, plus what they believe the market value for the property. So... does Michigan and/or the county and city do something different here? Really trying to understand whether there is an actual tax policy / structure problem, or as the quote at the bottom of the article indicates "We currently have an assessment division that’s not doing its job".
