There may be several reasons why Jiexiu housing prices have increased so outrageously:

1. Real estate developers may exaggerate when speculating on real estate: House prices, leading to inflated house prices.

2. Population increase and accelerated urbanization: With the acceleration of urbanization, people gradually migrate to cities, resulting in an increase in urban population, thus pushing up housing prices.

3. Increased demand for home purchases: Recruitment by some large companies or mining bureaus has stopped, causing some young people to choose to go out to look for job opportunities. This has led to an increase in demand for home purchases and may also push up housing prices.

4. Relaxation of provident fund loan policies: The relaxation of provident fund loan policies has enabled more people to afford housing loans, thereby increasing the demand for home purchases and thus pushing up housing prices.

In short, there are many reasons for the outrageous increase in housing prices in Jiexiu, including speculation by real estate developers, population increase and accelerated urbanization, increased demand for home purchases, and policy factors. It should be noted that the above are only possible reasons, and the actual situation may be affected by more factors.
