I’ve spent 54 days comparing an 85 m² coastal home with a similarly priced detached home in Seoul. The coastal option appears easier to maintain, while the detached house offers more control but potentially larger, irregular bills. I’m modelling transaction fees, insurance, energy use and resale liquidity. What else belongs on a practical year-two-and-beyond checklist—especially maintenance workload, vacancy risk and costs that are easy to underestimate after purchase?
