How Serious Are the Problems with Korea’s High-Rise Apartments? (Professor Kim Ji-ho)

An independent exercise, not a statement by the video creator or verification of every claim in the video.

Separate monthly operating charges from future repair funding

This is a hypothetical calculation, not actual project costs. Suppose 500 equally contributing households face a repair costing KRW 3 billion in 10 years, with KRW 600 million already available for that work. The remaining KRW 2.4 billion requires KRW 40,000 per household each month over 120 months. If the projected cost rises 20% to KRW 3.6 billion, the shortfall becomes KRW 3 billion and the required monthly contribution becomes KRW 50,000 per household over the same period. Low current charges alone do not establish a low long-term burden; compare repair scope, timing, reserves and actual implementation of increases separately. Adequate reserves also do not establish good outing or emergency access, so inspect the route from the door to sidewalks, transport and medical services independently.

Check for yourself

1. Do estimated costs, timing and available reserves refer to the same scope of work?
2. Are planned increases actually approved and collected, with arrears and additional repairs considered?
3. Can residents reach services and help if an elevator fails or driving stops?

Limits of application

Household counts, costs and timing are assumptions with equal contributions, no other reserve use, no interest and no arrears. Inflation, scope changes, emergency work and allocation by unit area are excluded; the monthly saving is neither total management charges nor a recommended standard. Actual costs and timing require professional inspection and project records; this calculation does not certify building safety or predict individual health.
