The reasons are as follows: First, Huaqiao in Kunshan was developed earlier, and now the house price is relatively high, with the average price reaching more than 20,000, while some good lots have reached 25,000 to 28,000. The future value-added space is obviously insufficient and the investment value is not great; Moreover, the housing price in Jiaxing city is slightly higher, and there are not many new buildings, which is more suitable for improved self-occupation groups. Jiashan began to develop in recent years, and now it is in a low price. Its geographical location and policy orientation show great potential for future development. In particular, the strategy of "Shanghai in the same city" has tied Jiashan's future closely with Shanghai. Therefore, Jiashan of these three cities is more suitable for investment than the other two cities.
