I’m assessing a 2-bed townhouse in Seoul priced at ₩1,063,000,000, with expected rent of ₩6,705,000/month. That gives a headline gross yield close to 7.6%. The building appears sound, but shared-building reserves could change the outcome materially. My conservative model already includes vacancy, management, routine maintenance and one larger repair reserve. Which local cost am I most likely underestimating—insurance, property tax, turnover, building contributions or something else? Also, what net yield would justify the risk for you?
