1. Location: Puyang City is located in the east of central Henan Province, which is relatively remote and far from many commercial cities, and may also affect housing prices.

2. Economic level: As a small and medium-sized city, Puyang's economic development and consumption level are lower than those of first-tier and some second-tier cities, which may also lead to relatively low housing prices.

3. Real estate policy: Puyang municipal government may adopt a series of preferential policies to attract population and enterprise development, such as land transfer and real estate tax policy, which will also have a certain impact on the formation of housing prices. It should be noted that the above factors are one of the possible factors that lead to the low housing prices in Puyang Tomorrow Star City, and there are other possible factors. To determine the specific reasons for housing prices, we also need to consider the specific situation of real estate, building quality, competitors, supporting facilities and other factors. I suggest you learn more from professional real estate agents or developers to get more accurate answers.
