Besides, the house you mentioned is really a small property right house. Buying and selling small property houses is not allowed by law, but now there are 6 billion square meters of small property houses in China, involving more than 200 million people. Most people can't accept the current housing prices, so the phenomenon of buying and selling small property houses is still very common in society. This is a social problem and the government can't do anything about it now. For a small property right house, you can buy it if you live by yourself, but you should pay attention to the quality of the lot and the house when buying it. The better the general location, the easier it is to remove. As for the future policy, it is hard to say. . . If you are going to invest in resale, it is strongly recommended that you don't buy such a house.
Also, some irresponsible intermediary companies can be fooled, so be careful not to listen too much. He's an intermediary. Just sell the house and get the money. The after-sale dispute is a dispute between you and the original owner, so in the process of buying, some of their words may not be fulfilled, so pay attention to your rational judgment.
My humble opinion, I hope it will be useful to you.
