In order to give full play to the power of social capital，meet the growing diversified demands of the elderly，and break the plight in elderly care market with a single subject，insufficient capital and limited service under the background of aging population，the State supports and encourages access of social capital to the elderly care market，which has provided an opportunity for property enterprises to conduct home-based community services for elderly. In this article，through the investigation of the property participation in the home-based community care practice in Jinsong North Community，Chaoyang District，the author suggests that the coordinated development of demand is a sustainable way for property enterprises as social capital to carry out home-based community service for the elderly. During the process of coordinated development of demand，property enterprises have taken defining the orientation of one’s own development as the root，judging the needs of the subject as the base，providing precision services as the core，strengthening resource integration as a shortcut，and cultivating aging professionals as the key. Only then can property enterprises play their own advantages in the process of property service+ elderly care service，and achieve sustainable development of this model，so as to realize a win-win situation of multiple subjects.
