There are four main reasons why the house is so cheap. First, the current policy allows rural collective land to enter the market, which will inevitably affect the decline of land prices and naturally affect the chain reaction of falling house prices. Secondly, the vacancy rate of houses is getting higher and higher. We often see that many properties have been handed over for several years, but only a few families have lived in them. Because many people buy houses in order to appreciate the house price in the future, it is particularly deserted at night, but these houses will be occupied one day, and these rich people in their hands have not sold their houses at this time. In fact, there is only one main reason, that is, the house price is too expensive, and they can't wait for these people to sell their houses. Third, it is only a matter of time before the real estate tax is levied in the future, which will deal a great blow to the real estate speculators who own multiple houses in the future. With the collection of real estate tax, the policy of restricting sales will be introduced, so that houses will no longer be listed and circulated, and houses will return to the residential property. Fourth, the demographic dividend has gradually disappeared. Even if the second child policy is liberalized, it will be difficult to fundamentally change the changes in housing demand, because there are already houses after 70 s and 80 s, but now there are houses after 90 s because they are only children and their parents have their own houses. The center of their life is no longer on the house, so the demand for the house will naturally decrease, so the house price will definitely fall in the future.
