Qu'est-ce que Jungdogeum (중도금) — interim payment ?

Jungdogeum (중도금) is an interim installment paid between the 계약금 (down payment) and the 잔금 (final balance). It is common in new-build pre-sales (분양) and larger transactions; many ordinary resale deals skip it.

Once 중도금 is paid, the contract is generally much harder to unwind, so it marks the point of firm commitment in a staged purchase.
