The area in Qingdao with the most affordable housing prices is typically found in the city's outskirts, particularly in districts such as Huangdao, Jiaozhou, and Laoshan. These areas offer more affordable housing options due to several factors. Firstly, the cost of living in these districts is generally lower compared to the city center, which includes popular areas like Shinan and Liwan. This is due to the lower cost of land and infrastructure development in these outer districts.

According to a report by the Qingdao Housing and Urban-Rural Development Bureau, the average housing price in Huangdao, Jiaozhou, and Laoshan districts was approximately 10,000-12,000 yuan per square meter in 2021, which is significantly lower than the average price of around 20,000-25,000 yuan per square meter in Shinan and Liwan. This price difference is primarily driven by the lower cost of land and construction in these outer districts.

Additionally, the government of Qingdao has implemented various policies to promote affordable housing in these areas. For instance, the government has allocated land for public housing projects, which are specifically designed for low and middle-income families. These projects often offer discounted prices and are located in the outskirts of the city, making them more accessible to those with limited budgets.

Furthermore, the transportation infrastructure in these outer districts has been improving, making it more convenient for residents to commute to the city center for work or leisure. The expansion of the Qingdao Metro and the development of new bus routes have significantly reduced commuting times, making these areas more attractive for those seeking affordable housing.

In conclusion, the outskirts of Qingdao, particularly in districts like Huangdao, Jiaozhou, and Laoshan, offer the most affordable housing prices. This is due to the lower cost of living, government policies promoting affordable housing, and improving transportation infrastructure.
