The purpose of this study is to find out the optimal amount of investment in constructing a portfolio of real estate investments in Korea. The Strategic Asset Allocation is sought when a portfolio is structured with domestic real-estate investments and bonds and short-term investments. The analysis method was derived by applying the Efficient Frontier based on the MVO model of Makowitz. As a result of the analysis, Assuming that the proportion of each asset should be invested to at least 10%, there were three possible portfolio alternatives. The ratio of Office Building to strategic asset allocation is 14%, Retail Building is 18%, corporate bond ratio is 17%, government bond ratio is 23%, and MMF is 28% etc. At this time, the optimal return range was between 3.3% and 3.7%, the risk range was between 4.57 and 4.79. In conclusion, it established asset allocation taking into account appropriate risks and return levels when constructing strategic asset allocation for domestic corporate bonds and government bonds and commercial buildings.
