You are mixing apples and oranges here. You're telling me how much property tax revenue this land generates, but every time you post something about it there is another feature that shows up. First it was a golf course with a bunch of homes around it, then it had shopping centers added to it. Maybe there's 1.8 million square feet of office space, too.
I'm trying to get a grip on how much property tax revenue a private golf course generates. Maybe your example isn't a good one, because there may be one "owner" of all the property around the golf course. I'm talking specifically about a stand-alone golf course (Upper Montclair in New Jersey, for example -- where they have a Senior PGA Tour event every June) without any adjacent homes on the same property.
Stand alone private clubs with no homes on it are a rarity.
