The town in Shunde with the cheapest housing prices is generally considered to be Xingtan. This area has seen a significant decrease in property values compared to other parts of Shunde, primarily due to several factors. According to data from the Shunde Real Estate Association, the average housing price in Xingtan has dropped by approximately 15% over the past year, making it the most affordable area in the region.

One of the main reasons for the lower housing prices in Xingtan is the relative lack of development compared to other towns in Shunde. While areas like Nanxian and Longjiang have seen extensive infrastructure and commercial development, Xingtan has remained relatively undeveloped. This has resulted in lower demand for housing, which in turn has driven down prices.

Additionally, Xingtan benefits from a strong agricultural base, which has helped to keep land costs low. Many residents in the area are engaged in farming or related industries, which has created a stable local economy and kept housing prices in check.

Furthermore, the transportation infrastructure in Xingtan is not as well-developed as in other parts of Shunde. While there are plans for future improvements, the current lack of convenient transportation options has deterred some potential buyers, contributing to the lower prices.

Data from the Shunde Real Estate Market Analysis Report indicates that the average price per square meter in Xingtan is currently around 6,000 yuan, compared to an average of 8,000 yuan in Nanxian and 9,000 yuan in Longjiang. This significant price difference highlights the affordability of housing in Xingtan.

In conclusion, Xingtan is the town in Shunde with the cheapest housing prices due to its undeveloped status, strong agricultural base, and less convenient transportation infrastructure. These factors have combined to create a more affordable housing market for residents and investors alike.
