Abstract: Currently, there is no clear legal definition of commercial housing consumer’s expectant property right in our country’s legislation, and there is no consensus in the theoretical community regarding the nature of this right. In judicial practice, there are inconsistent judgments in cases involving disputes related to this right. Therefore, this article proposes that the expected property right of commercial housing consumers should be defined as a guarantee-like property right. In terms of the structure of the right, it should be understood as a combination of priority rights and the right to purchase house payment debt. With the increasing number of disputes related to commercial housing consumer’s expectant property rights, there is an urgent need to clearly regulate this right in civil entity law and incorporate it into our country’s priority rights system, granting it the priority to receive payment ahead of construction project costs, mortgage rights, and other debts
