[Korea] LTV Unregulated 70%

Inputs and formula

The ratio on this page is fixed at 70%. It is the loan-to-value ratio commonly guided for ordinary no-home buyers in unregulated areas, or one-home owners on the condition that they sell the existing home.

The formula is simple. LTV limit = (market value × 0.7) − senior loan. With the 600 million KRW cap on, the smaller of that limit and 600 million KRW is the final available loan. Required own funds are market value − final available loan. Acquisition tax, brokerage fees, and moving costs are not included, so actual cash needed is more than this.

Desired-loan mode inverts the same 70%. Required market value = (desired loan + senior loan) ÷ 0.7. For example, to borrow 350 million KRW at 70% the market value must be 500 million KRW.

What this calculator shows and what it does not

What it shows is only the ratio limit versus collateral value. What it does not show is bank appraisal, income underwriting (DSR), maturity, rate, move-in, policy-mortgage eligibility, or multiple-home status. Even in an unregulated area, if income is short you will not get the full 70%. Conversely, even if the ratio limit is ample, if the monthly payment is a burden that home is hard to make yours.

The numbers are for catching your breath before a branch consultation. It is safer to get a bank pre-check before paying a deposit or interim payment.

If your situation differs, this is not the page

If the home is in Seoul or in an overheated-speculation or adjustment-target area, ordinary no-home rules are not 70%. Use Seoul/Gyeonggi LTV 40% for regulated ordinary cases, Seoul, Gwacheon, Seongnam, Dongtan etc. first-time 70% for first-time in the same areas, and Seoul, Incheon, Gyeonggi first-time 70% if you used to hear 80% in Seoul, Incheon, and Gyeonggi and that has been cut.
