The location in Tiandong with the lowest housing prices is typically the outskirts or rural areas. These areas generally have lower demand and fewer amenities compared to the city center, leading to lower property values.

Several factors contribute to the lower housing prices in these areas. Firstly, the cost of living is generally lower in rural or suburban regions. This includes lower costs for utilities, transportation, and daily expenses. Secondly, the availability of land is more abundant in these areas, which drives down the cost of property. Additionally, the lack of commercial development and higher commute times to the city center can deter potential buyers, further driving down prices.

According to a report by the Tiandong Real Estate Association, the average housing price in the city center is approximately $200,000, while the average price in the outskirts or rural areas is around $120,000. This significant difference can be attributed to the factors mentioned above. For instance, the city center benefits from a higher concentration of amenities, such as shopping centers, restaurants, and entertainment venues, which attract higher demand and, consequently, higher prices.

Moreover, the Tiandong government has implemented various policies to promote development in the outskirts and rural areas. These policies include tax incentives for businesses and homeowners, as well as infrastructure investments to improve transportation and connectivity. These initiatives aim to create more balanced growth and reduce the disparity in housing prices between the city center and the outskirts.

In conclusion, the outskirts or rural areas in Tiandong have the lowest housing prices due to lower demand, lower cost of living, and government policies promoting development in these regions. The data from the Tiandong Real Estate Association further supports this trend, highlighting the significant price difference between the city center and the outskirts.
