Depending on how the postal service works in your country, you can locate a clump of mailboxes in a rural area and simply add your own mailbox to the clump. You can then receive mail at that mailbox and use it as a ghost address, even though you own no property near there. For example, if the current mailbox addresses are 1040, 1042, 1046, and 1050, then you can add 1044 or 1048.
Today, this is very hard to do in the U.S. because of the way that the postal service now registers all addresses, but it worked before then. If you live in a country where the government is not centralized, organized, and computerized, it just might work.
