The most affordable housing prices in Xianyang are typically found in the city's outskirts and suburban areas. These locations offer more space for less money compared to the city center. According to the latest data from the Xianyang Real Estate Association, the average price per square meter in the city center is around $1,200, whereas in the outskirts, it drops to approximately $800. This significant difference is due to several factors.

Firstly, the city center is characterized by higher land costs and infrastructure development. The central areas are more developed with better access to amenities, schools, and transportation, which attracts higher demand and drives up prices. Conversely, the outskirts and suburban areas have less developed infrastructure and amenities, which makes them more affordable for buyers looking for value.

Secondly, the city's expansion has led to the development of new residential projects in the outskirts. These projects are often designed to cater to the growing population and offer more affordable housing options. Developers in these areas focus on providing basic amenities and infrastructure, which helps keep the costs down.

Additionally, the government's policies and incentives play a crucial role in making housing more affordable. The local government has implemented various programs to encourage the construction of affordable housing units, which has contributed to the availability of more affordable options in the outskirts.

In conclusion, the outskirts and suburban areas of Xianyang offer the most affordable housing prices. This is due to lower land costs, less developed infrastructure, and government policies aimed at promoting affordable housing. The data from the Xianyang Real Estate Association supports this trend, with the average price per square meter in these areas being significantly lower than in the city center.
