There are literal mansions on dozens of acres (with landscaping, ponds, etc) 3 miles from me that have a lower property tax than my 2000sq foot suburban home. They were purchased by a trust in the 80s or early 90's, and now the kids (or grandkids) live in it. My state limits how much property tax can be raised on a home until its sold, and then that number resets. It drives me a bit crazy..
