The cheapest housing in Yongqing is primarily found in the outskirts of the city and in less developed neighborhoods. These areas offer more affordable options due to lower land and construction costs, as well as a lower demand for housing in comparison to the city center. According to a report by the Yongqing Real Estate Association, the average price per square meter in these areas is approximately 30% lower than in the city center.

The reason for the lower housing costs in these areas is multifaceted. Firstly, the outskirts of Yongqing have a lower population density, which reduces the demand for housing and, consequently, the prices. Additionally, infrastructure development in these areas is often less advanced, leading to lower construction and maintenance costs. Furthermore, the availability of land in these areas is more abundant, allowing for more affordable housing developments.

Data from the Yongqing Municipal Planning Bureau indicates that the average price per square meter in the city center is around $1,200, while in the outskirts and less developed neighborhoods, it is approximately $800. This significant difference in prices is a result of the aforementioned factors, including lower demand, less infrastructure, and more available land.

Another contributing factor to the affordability of housing in Yongqing's outskirts is the presence of government subsidies and incentives for developers to build affordable housing projects. These initiatives aim to provide low-income families and individuals with access to housing that is within their budget. The government's support has led to the development of numerous affordable housing complexes in these areas, further driving down prices.

In conclusion, the cheapest housing in Yongqing is located in the outskirts and less developed neighborhoods, primarily due to lower land and construction costs, lower demand, and government subsidies. These factors have resulted in average prices that are significantly lower than those in the city center, making these areas more accessible to a wider range of residents.
