The reasons are as follows: 1, wide range: the shops outside the community are distributed around the community, covering a large geographical area. This means that the property needs to spend more time and resources to inspect, maintain and manage these shops.

2. Diversity: Different stores operate different businesses, such as retail stores, restaurants and service industries. Each store has its own unique needs and problems, which brings challenges to the property to provide unified services.

3. Complex relationship: the shops outside the community are related to the owners, tenants and customers. Property needs to coordinate and deal with problems among stakeholders, such as lease disputes and customer complaints, which requires high communication and coordination skills.
