Taxes on a Mobile Home

[Kyle M.]

For tax purposes. I'm building a projection sheet for some brand new mobile homes that I'm bringing into my park. Since they will not be attached to the land, how will the county/city look at them each year for their tax value? Will they appreciate or depreciate ?  If so, how much each year? Is there a leveling off point where they can't go under or above? Any input or real world experience would be greatly appreciated.
