I don't think anyone owns any real property anywhere in this country. Thanks to property taxes, we are merely just renting from the government.
I read here and there about people who own land patent property. They really own it and it is not taxed. However, the catch is that the land cannot be used as collateral for loans. Reason is, it cannot be seized, so it cannot be acquired by a lender in case of load default. I have read where developers are trying to get land patent property away from the owners, how, I don't know. Also, there isn't supposed to be any land patent property in the original 13 colonies, only west of some line. I don't know much about it. But it is interesting.
