When retirees in their late 50s decide to relocate to rural areas for farming, they only calculate land and housing prices while overlooking 'hidden costs' such as septic system installation (5-10 million KRW, ~$3,750-$7,500), farm road access paving (3-8 million KRW, ~$2,250-$6,000), winter heating costs (2-3x higher than urban areas), vehicle maintenance (two cars required), and hospital transportation costs. The first-year abandonment rate for rural relocators reaches 30%, with 'unexpected costs' being the primary reason.
Users enter their desired rural area (city/county/district), land type (paddy/field/forest), family size, and current urban residence on a web platform, which then displays a checklist of 50 hidden cost items beyond land and housing with auto-calculated estimates. It generates a '5-Year Total Cost Comparison: Urban vs. Rural Living' table and provides anonymous actual cost data from rural relocation predecessors in the same area as reference values.
