Final answer:
The main principle relating to progression and regression in real estate is conformity, reflecting how surrounding property values collectively influence an individual property's value.
These concepts tie into larger themes of political influence and economic strategies that govern urban development and societal growth.
Step-by-step explanation:
The main principle involved with progression and regression in the context of housing and land development is conformity.
These concepts represent how the value of real estate is influenced by the collective values of surrounding properties. Progression suggests that the value of the least expensive property will rise if it is surrounded by more expensive homes, while regression indicates that the value of the most expensive property may fall if surrounded by less expensive homes.
This principle is part of the broader understanding of how political influence, urban planning, and community advocacy shape the urban development process.
Feagin and Parker's sociological study explains the dynamics between political and economic leaders in controlling urban growth, including how land values are manipulated to benefit certain social classes.
Furthermore, urban development concepts such as convergence and the rural-to-urban shift relate to how population and economic growth patterns can impact urbanization and housing trends within a society.
