I read a news article that stated Trump chose the golf course for Ivana's grave because it exempts the location from a whole list of taxes. "Under New Jersey state tax code, any land that is dedicated to cemetery purposes is exempt from all taxes, rates, and assessments. Cemetery companies are also specifically exempt from paying any real-estate taxes, rates, and assessments or personal property taxes on their lands, as well as business taxes, sales taxes, income taxes, and inheritance taxes."
