Starting from the current situation of rural building cost control, this paper studies the current problems of rural building cost control, analyzes the inherent elements of its generation, and expounds the application value and approach of BIM technology in this field, in order to guide rural construction investment. The investment in rural housing construction is mainly direct cost, including labor cost, material cost and part of machinery cost. Labor costs, including the wages of contractors and small workers, occupy the main part of investment. The cost of materials includes raw materials, finished products and semi-finished products, and is the largest part of rural housing investment. The cost of machinery includes purchase and hire. It is mainly the cost of small construction machinery, such as concrete mixer and steel cutting machine, bending machine. In the rural economy, the awareness of compound interest is not clear, you may have heard of "interest rolling interest", and the specific number, whether it is worth borrowing, often cannot choose, and then choose to build a house loan, always feel that it will be a loss, and dare not apply for a loan.
