Real estate refers to land and any permanent structures or improvements on that land, such as houses, buildings, and other tangible properties. It encompasses both residential and commercial properties, including homes, office buildings, shopping centers, vacant land, and more. Real estate can be owned, rented, or sold, and its value can appreciate or depreciate over time. It plays a crucial role in the world’s economy, often serving as a significant investment vehicle and a primary source of wealth for individuals and corporations alike.
