In the real estate sector, price plays an important role and can lead to an optimal allocation of resources as long as there is no price bubble. Therefore, identifying the factors that lead to a price bubble in the real estate market should always be considered by economic policy makers. In this paper, an attempt was made to examine the impact of the central bank’s monetary policy through the bank credit channel and the government’s fiscal policy through the government’s public spending channel on the occurrence of housing price bubbles using agent-based models**. The research results show that if monetary authorities apply simpler rules for measuring mortgage creditworthiness, this action can cause a significant increase in the housing price bubble and unsustainable economic growth. Enforcing more measured and soft rules that ensure that the amount of the mortgage paid covers an acceptable amount of the housing price will lead to sustainable economic growth. As for fiscal policy, fiscal deficit policy and the increase in public spending in the context of economic prosperity, along with the increase in GDP, will also significantly increase inflation. Given the central bank’s inflation target, this could lead to a price bubble in the real estate sector and trigger a recession. However, if the fiscal deficit policy is applied in times of recession, it can reduce the severity of the recession and housing price bubble and improve the situation.
