The neighborhood in Nanning with the lowest housing prices is typically found in the city's outskirts or less developed areas. These areas often include communities like Qingtongxia, Xingbin, or Longsheng. The reason for the lower prices in these neighborhoods is primarily due to their location, which is further from the city center and commercial hubs. This distance results in lower demand and, consequently, lower property values.

Data from the Nanning Real Estate Regulatory Bureau indicates that the average housing price in Qingtongxia is approximately 6,000 yuan per square meter, while in Xingbin, it is around 5,500 yuan per square meter. In contrast, the city center neighborhoods like Qingxiu and Liuzhou, which are closer to commercial areas and amenities, have average housing prices of around 10,000 yuan per square meter. The difference in prices is attributed to the infrastructure, accessibility, and amenities available in these central areas.

Several factors contribute to the lower housing prices in the outskirts. Firstly, the infrastructure in these areas is less developed, with fewer public transportation options and fewer shopping centers or entertainment facilities. This lack of amenities makes these neighborhoods less attractive to buyers who are looking for convenience and immediate access to services. Secondly, the distance from the city center means that residents in these neighborhoods may have to spend more time commuting, which can be a deterrent for some potential buyers.

Additionally, the government's urban planning and development policies play a significant role in determining housing prices. The city government often prioritizes development in the central areas, leading to an influx of investment and infrastructure improvements, which in turn drives up property values. Conversely, the outskirts may receive less attention, resulting in lower prices.

In conclusion, the neighborhoods in Nanning with the lowest housing prices are generally located in the outskirts, such as Qingtongxia, Xingbin, and Longsheng. The lower prices are due to factors like distance from the city center, less developed infrastructure, and government urban planning policies. Data from the Nanning Real Estate Regulatory Bureau supports this analysis, showing that these neighborhoods have significantly lower average housing prices compared to the city center.
