Step-by-step explanation:
A specific portion of a city in which a sales associate or broker becomes an expert is known as a Farming Area. This term refers to the practice where real estate professionals focus on a particular geographical area to build up their expertise, connections, and knowledge about the local market. Rather than spreading their efforts over a broad area, they 'farm' a specific community or neighborhood, often leading to a higher success rate in their transactions due to their specialized knowledge.
