There are many kinds of real estate business, each of which plays an important role in the overall process of real estate transactions. One type of real estate business, for example, would simply be an appraisal business. Appraisal real estate businesses would provide expert services in appraising pieces of real estate, including the land, buildings and improvements made on the land, so as to come to some accurate judgment of the value of that piece of land.
Another type of real estate business might be a development business, which focuses on buying up land and then selling it later for more after that land has been developed in some capacity. Development real estate businesses would likely build buildings on pieces of raw real estate, or would renovate buildings already built on such pieces of real estate.
Other types of real estate businesses include corporate real estate businesses, which are real estate businesses, or sections of larger businesses, which focus primarily on maintaining and managing pieces of real estate owned by corporations and property management businesses which perform a similar service, except likely for private owners.
As the prior example demonstrates, real estate businesses might also theoretically function either within or for other businesses. For example, a relocation real estate business might assist corporations with relocating employees as needed.
All of these forms of business fall under the overall heading of real estate business because all of them are somehow involved with real estate property.
