Due to the large amount of capital investment and the uniqueness of the development product itself, real estate development projects determine that the cost management of real estate companies has a huge impact on the cost of a project. For example, in the product design stage, effective optimization of design may reduce a large amount of engineering and save construction costs; an effective innovation in product sales can speed up project sales and save a lot of sales costs and financial costs. The quality of cost management has a greater impact on the development costs of real estate companies.
