Step-by-step explanation:
It is true that neighborhoods that have built community amongst themselves have found the value of their properties to increase. Residents engage in various group behaviors that protect their 'turf' and indirectly boost property value, such as maintaining tidy yards, encouraging local authorities to uphold zoning laws, and collaborating on improvements to local schools, parks, and hospitals.
