To aggressively counter South Korea’s demographic headwinds, the government established the Newborn Special Mortgage & Jeonse Loan Program (신생아 특례대출) for households who welcomed or adopted a newborn child within the preceding 2 years.
This sovereign policy financing vehicle provides subsidized interest rates ranging from 1.60% to 3.30% p.a.—nearly half the prevailing commercial mortgage rate—with loans up to 500 Million KRW.
Crucially, the loan is completely exempt from Korea’s 40% Debt Service Ratio (DSR) ceiling (applying only 60% DTI and up to 80% LTV), vastly expanding borrowing capacity for Seoul metropolitan real estate purchases.
This master guide evaluates 2026 expanded income caps (250M KRW), 30-year interest savings calculations, and existing mortgage refinancing guidelines.

6. Frequently Asked Questions (FAQ)
Q1. Are unmarried mothers or cohabitating couples eligible?
Yes. Eligibility is adjudicated based on the child’s birth certificate and Family Relation Certificate rather than legal marriage status. Single parents are evaluated purely on their individual income.
Q2. Is there a mandatory physical occupancy requirement?
Yes. The borrower must move in and register their address within 1 month of loan disbursement and maintain physical residence for at least 1 full year. Failure to do so triggers immediate loan recall.
Q3. Can foreign nationals married to Korean citizens apply?
Yes. If a foreign spouse is registered on the Korean resident registration certificate and has given birth to a Korean citizen child, the household qualifies fully for the 1% mortgage loan.
