There are some relatively high-risk speculative investment methods in the real estate market, but they should be treated with caution because they are often accompanied by greater uncertainty and may lead to serious losses. Here are some of them: **Speculation of pre-sale properties**: - **Operation method**: Before the building is completed, by signing a purchase agreement with the developer, agree to purchase the future property, and then when the expected house price increase reaches a certain level, transfer the pre-sale property to other buyers to earn the difference. - **Risk**: Affected by various factors such as the developer's construction progress, changes in market expectations, and policy regulation, if there are problems with the construction of the building or the market turns, it may not be possible to smoothly deliver the house or it may be difficult to find a buyer to take over, resulting in investment failure. **Short-term speculation in second-hand houses**: - **Operation method**: Quickly buy second-hand houses, simply decorate or not decorate, and wait for the house price to rise in the short term before selling quickly. - **Risk**: When the market fluctuates greatly, the house price may not rise but fall after purchase. During the holding period, you will also need to bear taxes, property fees and other costs. In addition, frequent transactions may also face high transaction costs. If the market goes down in the short term, it is difficult to find a suitable buyer to sell in time. It needs to be emphasized that real estate market regulation policies are constantly changing. High-risk speculative investments are not in line with the policy orientation of “housing for living, not for speculation” and may also cause investors to face huge economic losses. It is recommended to look at real estate investment rationally and regard it more as a means of long-term asset allocation rather than a simple way to make speculative profits.
