Market overview
South Korean mortgages are dominated by KB Kookmin Bank, Shinhan Bank, Hana Bank, Woori Bank, and NH NongHyup, with Korea Housing Finance Corporation (KHFC) acting as a state-backed guarantor and securitizer. Most mortgages use 1-5 year fixed teaser rates blending to CD-rate or COFIX-linked variable rates thereafter. The Bank of Korea cut its base rate from 3.5% to 2.75% during 2024-2025, supporting affordability but with strict DSR (Debt Service Ratio) caps capping leverage.
Why 4.85% is the typical rate
4.85% reflects a typical 5-year fixed teaser mortgage rate for a salaried borrower at 70% LTV in early 2026, after BOK's easing. KHFC-guaranteed Bogeumjari Loan offers cheaper fixed rates (3.5-4.0%) for eligible borrowers under specific home-price thresholds.
Tax & regulatory notes
Mortgage interest is partially deductible (up to KRW 18 million/year for owner-occupied homes with long-term fixed mortgages, scaled by maturity). Property acquisition tax is 1-3% based on price (4% for second-home/multi-home buyers, higher for speculative zones). LTV caps are aggressive: 70% in regulated areas, 60% in speculation-warning zones, 40% in speculation zones (most of Seoul). DSR is capped at 40% of annual income across all loans combined.
