1. The house you bought has become an unfinished building. If you want to claim the loss, you can apply for the real estate license first, and then keep the relevant evidence of buying a house and file a lawsuit with the court. First of all, property buyers can go to the administrative department for industry and commerce to inquire whether the house is announced. If it has been legally announced, the buyer can apply for the real estate license at the housing management department with the proof issued by the industrial and commercial department and the original commercial housing sales contract, personal ID card and other materials.

2. jointly negotiate rights protection. After dealing with the ownership of property rights, you can contact the owners of the same community and get legal support; If the house you buy is only likely to be unfinished, then you can give developers more time to raise enough funds to complete the project after completion, which can reduce the losses of buyers; If the developer is insolvent and declares bankruptcy, and the house falls into an unfinished crisis, then the developer's finance will be auctioned by the court. According to the provisions of the bankruptcy law, buyers are more likely to wait for compensation from some real estate companies than creditors.

3. Trust the government. If the house is unfinished, the local government will intervene in different ways according to different situations; If developers are short of funds, the government will ask enterprises to raise funds or introduce partners; If it is illegal, then the government will require it to make rectification within the specified time; If the lawsuit involves economic disputes, then the government will also intervene; If the developer has gone bankrupt or can't continue the construction despite his best efforts, the government will take back his project according to law.
