Background
LTV began as an internal underwriting standard. After the Asian financial crisis, low rates and easy credit sent Seoul-area apartment prices soaring. In September 2002 Korea became one of the first countries to impose LTV caps as policy, setting a 60% limit in overheated zones. Along with Hong Kong and Singapore, it has used them more actively than almost anyone since. After high-LTV lending fueled the US subprime crisis of 2008, the IMF promoted LTV caps as a core macroprudential tool.
Calculation and caps
With a 70% LTV, a home worth ₩500 million supports a loan of up to ₩350 million. In practice lenders often subtract a small-tenant deposit allowance, so the real limit is lower. In Korea, first-time-home seekers typically get about 50% in regulated areas and 70% elsewhere. First-time buyers can get 80% (up to ₩600 million) anywhere, while multi-home owners face tight limits in regulated zones. The rules change often with government housing measures.
LTV vs. DSR
LTV sets how much the collateral supports. DSR sets how much your income can service. The lower of the two is your actual limit, so a pricey home can still be capped by modest income. Research suggests LTV tightening slows credit growth faster than policy rate hikes. Critics counter that it makes it harder for genuine owner-occupiers to buy. If you're planning a balance loan after a housing subscription win, check the LTV in advance.
