General terms:
* Landowner: This is the most common and neutral term.
* Proprietor: This implies ownership and control.
* Landholder: This is similar to landowner, but can also refer to someone who holds land for a specific purpose (e.g., a lease).
* Freeholder: This specifically refers to someone who owns land outright, without any leasehold obligations.
More specific terms:
* Estate owner: This refers to someone who owns a large estate, typically with a house and surrounding land.
* Rancher: This specifically refers to a landowner who raises livestock.
* Farmer: This refers to a landowner who cultivates crops.
The best word to use will depend on the context. For example, if you are talking about someone who owns a small piece of land, "landowner" would be the most appropriate term. However, if you are talking about someone who owns a large estate, "estate owner" would be more accurate.
