A more thorough explanation:

Realty

Realty is another term for real property, which refers to land and any permanent structures on it, such as houses or buildings.

• When my parents bought their house, they had to sign a lot of paperwork to transfer the realty from the previous owners to themselves.
• The realty company specializes in selling commercial properties like office buildings and warehouses.

These examples illustrate how realty refers to the ownership and transfer of land and buildings. When someone buys a house, they are not just buying the physical structure, but also the land it sits on. The realty company mentioned in the second example deals specifically with the buying and selling of commercial properties, which are often large and valuable pieces of real estate.
