Real estate refers to land, including the air above and the ground below it, along with any buildings or structures on it. It also includes rights to use and develop the land and its resources. Real estate is a significant area of investment and encompasses residential, commercial, and industrial properties. The real estate market involves the buying, selling, and renting of properties, as well as the development and management of real estate assets. Real estate is often considered a valuable asset class due to its potential for appreciation and the ability to generate rental income.
