공공임대주택 노후도에 따른 유지관리비용 예측

Abstract

Maintenance costs for housing shouldered by the rental business operator are continuing to increase together with the policy of expanding the supply of rental housing, while management by rental business operators is increasingly getting worse due to the restrictions on increasing rent and the lack of securing funds for rental business agents. Therefore, the study aims at enabling an optimized maintenance service by setting financing plans and budgets that are more credible by allowing the rental business operator to predict beforehand the maintenance costs. The study primarily analyzed elements that affect maintenance costs and then drew out a regression equation by forming a research model and applying regression analysis. Secondarily, the study analyzed the current status and analysis for each elapsed year based on the accounting data spanning ten years that were actually disbursed as maintenance costs and then calculating the standard price for each elapsed period, simulating a predictable future scenario. The study has proved a considerable level of linear relation between maintenance costs and elapsed years. Ten years after supply, maintenances costs have sharply increased, and assuming that the lifespan of rental housing is 40 years, it is predicted that the maintenance cost increase rate will balloon to a high increase rate of 25 fold when compared to initial supply(within 5 years on average 1,567 won).
