Housing and cost

In South Korea, jeonse is a deposit-only lease with no monthly rent. Where both values are available, the profile's monthly comparison estimates its cost as deposit × annual conversion rate ÷ 100 ÷ 12. Wolse is a separate lease with a monthly payment and its own deposit; that deposit is not included in the monthly figure.
