This happens on the personal side as well, where property tax rates are artificially depressed - or more accurately, subsidized - until the property changes hands. When we bought our nearly 30 year old house that had had zero improvements, additions, or renovations since initial construction, our property tax bill increased 300% and has since "stabilized" to +10% a year.
What is truly insidious about this is that it's impossible to guess or estimate until you've already purchased the home, and by then it's too late to do anything about it except complain at the courthouse, which might get you a year's abatement if you're lucky.
If we let property taxes just be whatever they "should" be without penalizing home-buying in the process you could at least know what you'd be paying rather than having to factor in a 3-5x increase.
