Cash can run short even when the home price is unchanged

Assume a KRW 500 million loan resets under its contract from 4% to 6% annually while monthly household net income falls from KRW 6 million to KRW 5 million. Interest alone rises from about KRW 1,666,667 to KRW 2.5 million per month, an increase of about KRW 833,333. Holding other monthly expenses at KRW 3 million changes the post-interest balance from about KRW 1,333,333 to negative KRW 500,000, producing a KRW 6 million cumulative shortfall over 12 months. The calculation shows why a stable or rising home price cannot immediately cover the gap when a sale takes longer.

Check for yourself

1. How does the shortfall change after including the actual reset date and principal repayments?
2. Have available cash during a delayed sale and any deposits due for return in the same period been calculated separately?

Limits of application

This is a hypothetical calculation, not an actual borrower’s case or a rate forecast. It compares interest alone and excludes principal repayments, taxes, one-off expenses and additional borrowing, so it is not an actual loan-payment schedule. The same reset shock does not apply to a loan fixed until maturity.
